0.5 Cubic Foot Portable Pressure Pot: 1/2 cubic foot capacity ASME approved pressure pot assembly complete with abrasive load hopper, air controls for portable use and 3" negative pressure abrasive load hopper dust eliminator assembly. Also available in larger 1 cubic foot pot capacity.
100% Welded: Often times less expensive machines are spot-welded using lighter gauge steel in the cabinet construction. All Media Blast machines, even the smallest, are 100% welded using 14 & 12 gauge steel for the construction of the machines. This will prevent cabinet leakage during machine operation and is a more desirable machine construction.
3-Way Valve: Often two separate valves are use to control the flow of compressed air into and out of the pot assembly. Media Blast uses one valve acting as two with one handle making operation simpler.
350 cfm / 550 cfm Blower: Radial Impeller, non-sparking, Class III dust collector blower assembly used to create a high air volume amount out of the cabinet for cabinet visibility... also moves air against static pressure resistance that takes the form of collected dust on the dust collector filter. This produces more cabinet air changes per minute for better visibility.... using the abrasive separator reclaimer prevents abrasive escape into the dust collector.
Abrasive Flow Control Valve: Most manufactures use a mechanical ball valve to regulate the flow of abrasive below the pot. Media Blast uses compressed air pressure to regulate abrasive flow eliminating valve wear.
Abrasive Mixing Valve: The abrasive mixing valve is used to meter the amount of abrasive entering the abrasive delivery hose. A properly adjusted abrasive mixing valve will eliminate all abrasive delivery surge and also allow re-adjustment when changing abrasive sizes. Machines without mixing valves or machines without quality mixing valves will never be capable of the fine adjustment required for the wide variety of abrasive sizes in the industry today.
Abrasive Separator: See Separator Reclaimer
Access Port [See Photo] : Pressure pots are used to pneumatically push the abrasive to the blast nozzle. Access ports are use to drain and clean the abrasive when abrasive change is required. Pots without access ports are hard to clean and often create problems if the abrasive gets wet. Without the access port it’s almost impossible to clean wet or nested abrasive from inside the pot assembly.
Air Requirements 15 cfm Maximum: Media Blast does not advise operation of the MicroBlast unit with abrasive delivery systems that require more than 15 cfm delivery. The MicroBlast air controls are for micro flow, 15 cfm and less.
Ambient Air Dryer: Moisture in the compressed air supply causes abrasive flow problems and dust collector filter problems. MBA’s unique inline ambient air dryer requires no floor space and mounts directly onto the blast cabinet.
Air Regulator-Filter-Water Trap [See Photo] : Any application requiring precise control during the blasting process, sandcarving and halftones, requires precise control of the compressed air. These controls make adjustment of the compressed air possible. In addition, the compressed air used should be moisture free.
Air Velocity Wing Panels: Two parallel panels close together used to create faster air inlet velocity.
ASME Approved Pressure Vessel: American Society of Mechanical Engineers Code meet city and state requirements for most commercial and industrial installations. Each unit is built, inspected and tested to meet rigid standards adopted by ASME and inspected by independent sources. Less costly pressure vessels have no such rating.
Barrel Reclaim Separator [See Photo] : This option is available with the pneumatic abrasive conveyor in lieu of the high efficiency cyclone separator reclaimer used with the finer abrasive. It is used for applications that require conveying the abrasive outside the blast cabinet when the abrasive size is large, 60-120 mesh. This option produces a longer lasting separator style when used with larger cutting abrasives.
Bar Grating [See Image] : Grating material is used because of its ability to span large unsupported distances in large abrasive blasting cabinets or is often used when high wear abrasive applications are present.
Batch Loads [See Photo] : Term used to describe small parts processing without operator contact. Batch loads are processed using a rotating basket or barrel assembly. Random part mixing coupled with directional blast permit part processing in a given time period without the need for a machine operator.
Blow-Down Controls: The addition of Blow-Down Controls allows the quick depressurization of the blasting pressure pot permitting pot re-fill. The smaller the blasting pot the more advantageous the blow-down controls.
Blow-Off Gun Assembly: All production cabinets manufactured by Media Blast include inside cabinet blow-off gun assembly. This feature is also available as an option on the Light Duty and General Purpose blasting cabinets.
Boron Carbide: A material used for blast nozzles when a cutting abrasive is used. Boron Carbide will outlast tungsten carbide 4-6 times with only double the cost.
Brown Fused Aluminum Oxide: Cutting abrasive 9.0 hardness on the Moe’s Scale of mineral hardness, diamond equals 10. Particle for the most part retains size, dull out loosing cutting ability and reduces cleaning speed.
Cartridge Filter [See Photo] : Unlike other filtering materials, (cloth), used in dust collectors, the filter cartridge has a certified nearly HEPA quality. Cloth filters consist of a woven material that stretches during the cleaning process reducing the filter efficiency. Filter cartridges also produce greater filter collection surface in a smaller required filter area. Replacement time and cost is reduced significantly by purchasing a machine that uses filter type cartridges.
Cartridge Style Shop Vacuum: All shop vacuums are not created equal…because price is not the issue look to the performance of the vacuum. Filter collection surface area is greater when you choose one with the filter cartridge. This permits longer operation before filter cleaning. Look for the unit with the largest blower cfm rating. The normal cfm range is 80-150 cfm, 150 cfm being best.
Choke Plate: Device used to create increased air velocity into the blast cabinet.
Clearview Window [See Photo] : Oversized operator’s view window.
Clearview Window Sweeps: Air inlet locations are used to reduce the dust build-up on the inside view window surface.
Collapsible Side Table: Bolts to the side of the cabinet and produces a collapsible shelf.
Contained Dust Discharge Assembly [See Photo] : MBA expands upon its popular hopper style dust collector by offering a contained dust discharge assembly (standard with HEPA filtration). This assembly incorporates a slide gate on the bottom of the dust collector hopper. When the slide gate is opened, the dust is released through a duct and into a dust collection vessel. If the dust collection vessel is lined with a bag, the vessel top can be removed and disposed without the operator ever being exposed to the dust. This option is recommended for operations blasting with hazardous abrasives or on materials that may release hazardous material dust. Slide gates and taller hopper heights are available to accommodate drum waste disposal. Dust collection systems that allow the use of a full size steel drum are also available.
Cutting Abrasive Package [See Image] : Should be included on machines operating with high wear or cutting abrasives types. Consists of window protector, boron nozzle, white polyethylene cabinet wear plate, heavy-duty bar work grates and steel hopper wear plate. Some machine models already include some of these items.
Cyclone [See Photo] : A pneumatic centrifuge used to separate and retain abrasive sizes 150 mesh and smaller. Cyclone Separators also help keep the abrasive dry and introduce air into the abrasive to permit more uniform abrasive delivery of finer sizes.
Directional Blasting: A term used to describe abrasive blast machinery equipped with handheld or fixture held blast guns. Allows certain part areas to be processed while preventing other areas from being processed. Always operated using compressed air to convey the abrasive media to the part surface.
Direct Pressure [See Photo] : Direct Pressure machines use a pressure vessel to pneumatically push the blast media through a single abrasive hose and out the blast nozzle. Direct Pressure machine are capable of operation with heavy abrasive, steel shot or steel grit, in addition to most other abrasive blast types and sizes.
Door Interlock: See safety door interlock
Double Skinned, No Spill Door with Heavy Duty Appliance Style Latch [See Photo] : MBA uses a heavy duty latch attached to a double wall, 14 gauge steel door. An MBA door will not warp or flex. MBA may build the only blast cabinets that do not leak abrasive when the doors are opened.
Downdraft: Term used to describe the direction and speed of air flow. Commonly used to describe the speed of air just above the work surface of a pollution control workbench.
Dual Feed Pressure Pot [See Photo] : This pressure pot assembly, 2.8 cubic foot capacity, allows continuous operation of the pressure pot assembly during part processing. This feature consists of two integrated pressure vessels on a timed circuit that allows collection pot refill during machine operation and also blast pot refill during machine operation. Includes all required solenoids and timers, also includes the special pressurized abrasive flow control valve for proper operation and abrasive flow adjustment. Adjustable timers permit proper circuit setting for nozzle orifice size used during blasting process.
Easy Load and Fill Pot Assembly: Because the pot is always pressurized during operation and the CrystalBlast machine permits single valve pot depressurization, you can depressurize the pot and push the easy load handle to open the pot for abrasive reload.
Ergonomic Sit Down System [See Photo] : This option is available as a bolt-on padded shelf that attaches to the CrystalBlast and PrecisionBlast Micro Direct Pressure Blast Machines. It is also available as a system that can be incorporated into a complete Custom blast cabinet; the custom option includes a different window slope and the window is lowered to improve visibility into the blast cabinet. The blast cabinet hopper has been redesigned so that the operator can sit comfortably while blasting. An adjustable armrest and shrouded foot pedal completes the package.
Exhaust Blower: The machine exhaust blower is used to create cabinet visibility and is necessary for efficient operation of abrasive separator reclaimers. Separator reclaimers remove unwanted dust and spent abrasive from the cabinet. To establish the number of cabinet air changes per minute made possible by the exhaust blower, take the cabinet blast chamber area in cubic feet and divide it into the exhaust blower cfm rating. Never count the machine hopper when calculating the cabinet volume.
Exhaust Silencer [See Photo] : The Exhaust Silencer is used to reduce the noise level created by any class III dust collector exhaust blower. Larger blowers used to creating better cabinet visibility also create noise levels unacceptable for continuous machine operation.
Expanded Cabinet Heights [See Photo] : MBA offers two cabinet heights on the most popular cabinet sizes (3636, 4836). The standard height production blast cabinet has a 30” working height and a view window angle of 40º. This allows ergonomic blasting of smaller parts without putting your nose against the view window. Our expanded height cabinet offers 36” of working height with a view window angle of 17º. This window angle is more efficient for taller parts that won’t fit in the standard height cabinet. If the normal cabinet heights will not suffice, MBA offers extended heights as an optional feature.
Expanded Two Cartridge Dust Collector Upgrade [See Photo] : This option provides more filter surface area (440 sq. ft.) when dusty abrasives are used or when the cabinet usage is three + hours per day.
Filter Cycle Cleaning Gauge [See Photo] : This feature is standard on all MBA production cabinets and an option or unavailable on the other manufacturers’ cabinets. Clean filters are an important part of the maintenance process. Neglect will result in significant repair costs and lower productivity (due to poor visibility), so it is critical to know when to change the filters. The MBA filter cycle cleaning gauge helps remind the operator when critical maintenance is due.
Fine or Ultra Fine Abrasive: Any material pneumatically propelled through a blast nozzle is commonly known as abrasive or blasting media. Fine and Ultra Fine abrasive measures 150-325 mesh in abrasive particle size.
Flexible 3/8” OD Long Life Blast Hose: Detailed work is impossible using large unruly blast hose. Media Blast has installed a high wear hose with an outside diameter of only 3/8” and calls this assembly the flexible whip hose assembly. Great of small jobs that require exact detail and control.
Flexible Pot Valve: Most CrystalBlast and PrecisionBlast machines include the flexible pot valve. This permits low pressure On-Off blasting without pot valve leakage. Critical for low pressure blasting and half tone processing in the sandcarving industry.
Foot Operated Blast Valve: Foot operated blast control allows the machine operator maximum mobility inside the blast cabinet by permitting control of the blast cycle using on-off foot operated pedal. This is important when operating inside smaller cabinet sizes. This also creates a smaller more compact blast gun size. Trigger controlled guns are large and troublesome when installed inside a blast cabinet.
Frictional Heat [See Photo] : Dry abrasive blasting generates surface heat on the part being processed. This frictional heat can damage thin parts or parts made of certain materials such as plastics or composites. Frictional heat increases when the compressed air being used is increased and this is the single most important factor that reduces part-processing time when using larger gun sizes.
General Purpose: A term used to describe a “hybrid” between light duty and production machinery. The cabinet is large, but the dust collector capacity is limited. General Purpose or non-production machines are ideal for infrequent use on larger parts.
Glass Window Protector: Commonly called “Window Protectors” are used to protect the operator view window during machine operation using cutting abrasives. Cutting abrasive are capable of window etch and using a sealed secondary window assembly located inside the machine to protects the normal view window from etch. Using softer material, plastic sheets, is undesirable due to the soft nature of the protector.
Gun Holding Fixture [See Photo] : Enables the operator to hold and manipulate the part to be blasted with both hands because the nozzle is fixed in position. This option is recommended for operations that blast small or difficult to hold parts.
HD Kit : Media Blast offers two models of some Light Duty machines. Standard models use a smaller gun size and HD models use a larger blast gun assembly. Using a larger gun is possible when the machine includes the HD Kit. All HD Kits include the larger 350 cfm - 1/2 hp radial blower, abrasive separator reclaimer and tubular dust collector. The smaller cfm Shop Vacuum is no longer used for the dust collector on and HD model. The HD Kit can be added to any Standard model at any time allowing better cabinet visibility with a blower that produces 30 air changes per minute and a separator reclaimer that removes the dust and dirt from the abrasive. Vacuum blowers are brushed motors for intermittent use only and they can be damaged if in operation for too long a time period. The HD Kit includes a blower with 115% Duty Cycle Rating.
HEPA Filter [See Photo] : This filter should be installed when hazardous materials are being blasted (e.g. chromium, cadmium, nickel, zinc, lead, asbestos, or radioactive materials). HEPA is an acronym for High Efficiency Particulate Air Filter, which was used in U.S. military specifications beginning around World War II.
High Limit Pressure Control: Often blast machine controls have a 125-psi operating rating. Installation of the High Limit Pressure Control prevents damage created by two stage air compressors that create line pressure up to 175 psi.
Hopper Bottom Dust Collector [See Photo] : For ease of cleaning always look for machinery using a hopper bottom dust collector. All Production type machines manufactured by Media Blast are equipped with dust collector dust storage hoppers. This also allows removal of collected dust into plastic storage bags preventing unwanted dust escape during machine service.
Hopper-Less Construction: Elimination of the machine hopper can be accomplished using an air swept floor section to include pneumatic abrasive conveyor. The normal air swept height is 12-13 inches resulting in more area for blast workspace and a lower machine height.
Hopper Scalper Screen: Removes large material and debris from the abrasive and protects the abrasive mixing valve from unwanted debris nesting around the valve.
Installation Kit: Fitting…Clamps and Hoses necessary for machine installation. Used on the smaller cfm rated blast machine, 25 cfm and less.
Laminated Safety Plate Glass Window: Many types of materials are used to meet the safety requirements for viewing windows for blast machinery. Safety plate, the glass used for front automobile windshields, is the best. The bonding of two sheets of glass together with plastic prevents glass shards from occurring during breakage. Other manufacturers use Plexiglas to meet the safety standards but Plexiglas scratches very easily and creates static electricity which can cause the abrasive to stick to the view window creating poor visibility. This is an inferior substitute for safety plate glass.
Light Duty Blaster: Light duty describes machinery used on a non-daily basis. One feature missing from light duty machinery is the production style dust collector with large filter surface area. Light duty machines are the least costly to purchase and usually have cabinets measuring 24 inches by 24, 30 or 36 inches. These cabinets are generally of spot welded construction, however all Media Blast machines are 100% welded construction. Most light duty machines operate with no more than 20 cfm of compressed air.
Long Life Gauntlet Sleeves: Permits operation of the machine without the gloves attached or allows attachment of operator gloves.
Long Wear Abrasive Hose: A hose material used when high wear cutting abrasives are being used. This type of hose eliminates the frictional wear created on normal abrasive hoses.
Low-Pressure Cycle: Using a Sandcarver at low pressures, 5-20 psi, can be difficult when not using a flexible pot valve. When the unit includes low pressure cycling the pot valve is flexible and on-off cycling at low pressures is possible.
Low-Pressure Processing: Thinner mask material, 2 mil, requires low pressure processing. Pressure pots that require capping are cumbersome to operate. Pots attached to machine often require 30 psi for pot valve closure. Media Blast with its unique design permits low-pressure On-Off cycle with pressures as low a 5-10 psi.
Maintenance Meter or Hour Meter [See Photo] : This feature can simplify the maintenance of your new MBA blast cabinet. Use the non-resetable hour meter to create a logbook indicating basic machine maintenance schedules including abrasive changeout.
Magnahelic Gauge [See Photo] : The magnahelic gauge monitors the condition of the dust collector filters (or HEPA filters) by monitoring the differential pressure between the clean and dirty side of the filter. The magnahelic gauges are available with or without setpoint indicators and with and without indicator light. The setpoint indicator can triggers a red light when the factory preset differential pressure has been reached indicating that it is time to change the filters.
Magnetic Separator: Often used to remove undesirable metals from plastic abrasive during operation.
Manual Reverse Pulse: Description of an assembly used to reverse the airflow direction inside a machine dust collector to allow the removal of collected dust from the filter surface.
Manually Operated Hopper Vibrator: Used to vibrate the abrasive through a smaller scalper screen size.
Micro Hoses: The CrystalBlast line of sandcarving equipment uses the smallest abrasive hoses in the industry. Ease of use is what sandcarving is all about and all CrystalBlast units come standard with the flexible 3/8” OD abrasive hose.
Micron: Unit of measurement, 25 microns equals .0012 or 1/25,000 of an inch.
Mixing Valve: The mixing valve or abrasive mixing valve is use to regulate the flow of abrasive to the gun.
Mobile Workcarts and Track [See Photo] : For large, heavy and awkward objects that need to be blasted, the mobile work carts and track allow the objects to easily be loaded and unloaded from the cabinet. This eliminates the need for potentially dangerous clamshell style cabinets. All mobile workcarts are equipped standard with internal cabinet track, locking turntables and 300 pound capacity. Various lengths of external track extensions and powered operation are available.
Padded Arm Rest [See Photo] : The padded armrest permits the old familiar “elbows on the table”. Feels good not only on your arms but the back as well. This options bolts to most Media Blast machines and is listed in the available option section.
Pinch Valve: Pneumatic valve used to control the on-off abrasive flow.
Pneumatic Cleaning Button: Permits one button cleaning of reverse pulse cleaning dust collectors. Always located in an easy to use operator friendly location.
Pneumatic Conveyor [See Photo] : A pneumatic conveyor is a device used to convey abrasive pneumatically during operation of the blast cabinet. Used with the cyclone separator for separation of fine and ultra-fine abrasive. Also used during operations with larger cabinet or multiple cabinets requiring standard operator heights. Commonly includes abrasive conveyor ducts.
Pneumatically Controlled Abrasive Circuit: Media Blast uses pneumatic controls to start and stop the blast cycle. This eliminates the requirement of cumbersome ball valves operated in a confusing pattern. In addition this also eliminates the large On-Off valve located behind less expensive pressure pot nozzle assemblies. All circuits are foot pedal controlled.
Polyester Filter: Filter cartridge that is washable. Also used for applications to permit faster cartridge cleaning.
Pop-Up Work Grate: Normal machine work surface that collapses to permit passage of larger parts through the machine during operation. Allows the machine to be used for two separate operations, small parts and large panels.
Pressure Pot [See Photo] : Used with direct pressure blast machines to pneumatically push the abrasive. Pressure pots will produce a fastest abrasive velocity, the most concentrated abrasive patterns and also operate with the heaviest of abrasives.
Production: Production blasting machinery is machinery used on a daily basis. The defining factor in production machinery is the dust collector. Production machines require large amounts of dust collector filter surface area. The greater the surface area, the greater the capacity for storing collected dust during operation. Dust collectors with dust storage hoppers are easier to clean and therefore cleaner to operate. Production cabinets are usually of heavier, 100% welded construction, with the greatest variation of cabinet sizing.
Protector Glass: The protector glass is installed under the safety plate view window. It prevents view window etch and allows protector window replacement for a durable inexpensive way to protect the machine sight window.
Quick Change Nozzle: Permits nozzle changing in seconds without the use of tools.
QwikStrip Nozzle: Long high velocity nozzle used to maintain high abrasive velocity, high impact velocity and dense abrasive particle concentration. Longer than usual nozzles and possible for use on direct pressure machines only.
Raised Operator Platform [See Photo] : Raising the operator height and supplying the operator platform allows placement of the pressure pot below the machine hopper and produces a better machine hopper slope for hopper to pot feed. This allows a larger cabinet without the need to supply a pneumatic conveyor that greatly increases the operating cost of the machine.
Replaceable Hopper: MBA has the only truly modular blast cabinet. If the hopper wears out after many years of use, it can easily be replaced because it is not welded to the cabinet. If a client’s blasting requirements change, MBA’s production blast cabinets can be easily converted from one style to another simply by changing the hopper or adding accessories. For example, a production siphon cyclone cabinet can easily be converted to a pressure cyclone, a siphon or a pressure blast cabinet. While many manufacturers can convert between siphon cyclone and pressure cyclone, no other manufacturer can measure up to MBA’s flexibility. MBA is the only manufacturer that offers an advertised optional system that allows the user to automatically dispose of the abrasive after one cycle or use the system as a normal abrasive blast system that automatically recycles the abrasive.
Random Part Mix: Method used to describe part mix during tumble blast. The faster the random part mix, the faster the tumble cycle and the greater the machine production.
Reverse Pulse or Timed Reverse Pulse Cleaning [See Photo] : A device used to clean the dust collector filter surface using a pulse of compressed air. This type of assembly is advised when high humidity conditions exist. Can be automatic or manual pulse, multiple or single cartridge application.
Roll Up Side Access Doors [See Photo] : In years past some side access doors were vertical lift doors. Today’s technology allows construction of the side access door as a contained roll-up door assembly. This permits the addition of powered gearmotor assembly and rubber inside door lining. Closing the door inside the machine hopper is an advantage when using this type of access door.
Rubber Dipped Baskets and Barrels [See Photo] : Tumble Basket and Barrel machines require the parts to be rotated inside the barrel assembly. The parts offer the required protection for the baskets and barrels during the blasting process. Often the steel basket or barrel requires rubber dipping to prevent part damage during the process when the parts rub against the steel barrel surface.
Safety Door Interlocks: Standard on all production blast cabinets and optional on all light duty cabinet styles. A safety door interlock shuts off the air to the blast nozzle while the door is open or if the door is opened while blasting is in progress.
Safety Plate View Window: Glass view windows are best because unlike Plexiglas or plastic, which attracts abrasive dust via static electricity, glass is a more durable static free material. Safety plate glass is one of the safest material because unlike tempered glass safety glass it has 2 piece of glass bonded together with a single clear plastic sheet between.
Secondary collection hopper: Not all applications require the same scalper screen size and this secondary hopper permits scalper screen change.
Separator Reclaimer: Separator Reclaimer or Abrasive Separator Reclaimer prevents the loss of usable abrasive when the exhaust blower exchanges inside for outside cabinet air creating the negative cabinet air pressure. Abrasive separator reclaimers are pneumatic centrifuges capable of separating usable abrasive from dust and unwanted, worn abrasive. This device allows usable abrasive to circulate over and over inside the abrasive cabinet while removing unwanted dust a spent abrasive. Abrasive separator reclaimers are available in different efficiency ranges, which should be matched to the abrasive size in use. Some separators operate with media sizes 0-150 mesh and others are intended for finer material of 180 –400 mesh. In addition, separator reclaimers are available in different cfm ratings, with larger separators for larger exhaust blowers.
Shrouded Foot Pedal Assembly [See Photo] : An OSHA approved shrouded foot pedal assembly is available as an option to MBA’s standard foot treadle. To accommodate the shrouded foot pedal assembly, the front leg brace is moved 8” back from the front of the cabinet.
Sifting Screen: Fine stainless steel wire cloth attached to pressure pot assembly to eliminate abrasive debris during pot refill.
Silencer: A blower silencer is used to reduce the noise level created by any dust collector blower assembly. The smaller the room the more critical the noise level becomes making silencers very desirable.
Silicon Carbide: Cutting abrasive 9.5 hardness on the Moe’s scale of mineral hardness, diamond equals 10. Extremely sharp particles but due to the hardness is prone to breaking into smaller sharp pieces. Looses its cutting speed because it continually breaks into smaller pieces with less mass.
Single Pot Blow-Down Control: Media Blast designed a system to permit single valve operation of the pressure pot assembly. Open the valve to pressurize the pot and permit blasting when the foot pedal is activated. Close the valve to depressurize the pot permitting pot refill. One valve does it all on the CrystalBlast and PrecisionBlast models.
Single Power Source [See Photo] : Machines with fractional motors operate from 120-volt power source. Machines with increased motor horse power,1 hp and above, are available with electrical box, transformer for low-voltage operator control, magnetic starter, heater and low-voltage fuse protection. This option allows supply voltage and phase choice by the customer.
Single Valve Blow-Down Control: Often multiple valve are required to depressurize the pot and fill with abrasive. Media Blast uses a special valve to do all functions permitting easy understandable pot control.
Siphon Blast: A term used to describe the type of abrasive delivery system used on an abrasive blasting cabinet. A siphon machine uses an injection gun to create suction on the abrasive supply hose. The abrasive hose then conveys the abrasive, using suction or siphon, to the gun where the compressed air hose is used to accelerate the abrasive. All siphon type machines include two hoses on the abrasive blast gun assembly. Siphon machines are the most common type of blast machine. All siphon gun assemblies include an air jet used to create the siphoning effect and also establish the amount of compressed air required to operate the machine.
Sight Window: Unlike the operator view window the sight window is used to permit outside light entering inside the cabinet. Commonly used on wet blast machine to allow outside light installation.
Soda: Soda or baking soda is a blast abrasive used to for one shot applications that require disposal of abrasive due to part contamination. Also used to prevent part damage during the cleaning process.
Soda Delivery System [See Photo] : Optional Direct Pressure system used to deliver soda in the Blizzard model blast cabinet.
Stainless Steel Sifting Screen: Located between the machine hopper and pot to prevent foreign debris from entering the pot assembly.
Stand up or Sit down Operation: Media Blast manufactures ergonomically designed machines for sit down operation... Some models are offered with longer leg assemblies offering choice. Many of the CrystalBlast units are available in two styles, ergonomically designed sit-down units or taller stand-up models.
Static Discharge Kit: Static electricity is generated when two dissimilar materials are rubbed together. This is a condition that is exaggerated by climate. The static ground kit prevents the cabinet from acting as a condenser when the abrasive comes into contact with the steel cabinet walls, this prevents the static charge build up inside the cabinet.
The Kit: Some parts are best kept on the shelf and not in the mail…”The Kit” includes high wear spare parts that can be less costly on the shelf than the overnight delivery charge. Classified as wear items, these are the special parts that would keep any CrystalBlast from operating and you from meeting that important delivery date.
Timed Window Wash: Clearwater rinsing assembly, timed, to provide a momentary pulse jet of clean water against the operator view window…all water used is removed from the cabinet to prevent reduced slurry concentrations. May be used for cabinet water make-up.
Tool Free Maintenance: Change windows, nozzles and hoses without the need for tools.
Touch-Up Paint Kit: 8 oz. paint and disposable aerosol sprayer…
Track Extensions: See Mobile Workcart and Track
Tumble Barrel or Basket [See Photo] : While most applications today using cabinets require operator directional blasting, some parts because of their size and quantity can be finished in batch loads using a machine equipped with a rotation device usually described as a tumble barrel. The term barrel usually signifies a horizontally mounted barrel with the rotation axis horizontal. Tumble barrel machines process parts up to 5 inches in length.
Tumble basket machines usually describe an open top basket mounted with the rotation axis at 45 degrees from horizontal. Basket machines allow processing of longer parts and usually require hand unloading of the parts being processed. Tumble barrel machines are self-unloading because of the horizontal rotation axis of the barrel permits jog rotation and unload.
Tumble Basket: See Tumble Barrel Above
Tungsten Carbide Nozzle: Heavy metal powder compressed under pressure to from a very hard and durable blast nozzle material.
Turntable [See Photo] : Heavy or awkward parts are more easily moved inside a blast cabinet with a turntable. The turntable can increase productivity significantly. Choose from manual or powered turntable models available in many sizes (up to 48” diameter) with standard capacity of 500 pounds (heavier capacities available). The turntable tops all ride on double sealed bearings. All MBA turntables are slotted for installing fixtures and are equipped to lock in position if desired.
Urethane Pot Valve: Most pressure pot assemblies use the standard steel pot valve assembly for high volume high pressure blasting. All CrystalBlast units use a flexible pot valve material or urethane for low pressure low volume processing. This is important when considering sandcarving machines.
Vaccuum Cleanup Assembly [See Photo] : MBA is the only manufacturer in the industry that offers this unique option. MBA converts the dust collector into a shop vacuum capable of cleaning up the work area around or cleaning the abrasive out of the blast cabinet. This option requires the dual cartridge dust collector and the 1,160 cfm exhaust blower.
Vac-U-Clean Abrasive Separator Reclaimer: See Vacuum Separator Reclaimer Below
Vacuum Separator Reclaimer: Separator Reclaimer or Abrasive Separator Reclaimer prevents the loss of usable abrasive when the exhaust blower exchanges inside for outside cabinet air creating a negative cabinet air pressure. Abrasive separator reclaimers are pneumatic centrifuges capable of separating usable abrasive from dust and unwanted worn abrasive. This device allows usable abrasive to circulate over and over inside the abrasive cabinet while removing unwanted dust a spent abrasive.
Vertical Top Loading Access Door [See Photo] : Low cost blast machines often have poor quality side access doors. This type of door construction permits abrasive dropout when the door is opened. Having a Top Loading Access Door eliminates this condition. This type of door configuration is desirable when smaller cabinets are being considered.
Wet Blaster: While most applications today require dry blasting, some remain that are truly jobs for wet machinery. The frictional heat generated by dry machines can destroy some parts. Using the wet type of equipment can eliminate the frictional heat generated during part processing. Another plus with wet machinery is the ability to produce a chemically clean part surface with minimal surface remove. Using 4000 to 5000 mesh abrasive is not an option when using a dry type machine but operation of this abrasive size is possible when using a wet type blast cabinet.
Wheel Kit [See Photo] : This option included 4 locking steel casters allowing the movement of smaller more compact blast cabinets.
White Aluminum Oxide: Cutting abrasive 9.0 hardness on the Moe’s scale of mineral hardness, diamond equals 10. Iron free and used often for medical processing. Particle breaks into smaller sharp particles similar to silicon carbide and looses cutting speed because particle has less mass.
Window Molding Tool Kit: Media Blast uses positive sealing window molding to produce a 100% sealed view window installation. Using the window molding tool kit allows easy installation of the operator view window if replacement is required.
Window Protector Assembly [See Image] : Commonly called “Window Protectors” are used to protect the operator view window during machine operation with cutting abrasives. Cutting abrasive are capable of window etch and using a sealed secondary window assembly located inside the machine protects the normal view window from etch. Using softer material, plastic sheets, is undesirable due to the soft nature of the protector.
