Suction Type Blasting Units
“Venturi” or suction type blasting units provide an appealing and lightweight pistol grip blast gun. The abrasive media used for the process is contained in a storage hopper for use. Line air pressure moves through the air hose and an orifice toward the blast gun or nozzle, which creates the venturi or siphoning effect. This picks up the media from the storage area, moves it through the hose and out of the blasting nozzle for impact against the work surface of the part.
Normal blasting pressures range from 80 to 100 psi.
There are many different standard size suction type cabinets available. Advanced Deburring & Finishing can recommend small units all the way up to very large machines depending on your needs. Custom units are not uncommon in applications that require the entire part to be placed inside the cabinet.
Turntables are a great addition to suction type units that help to move or turn parts as the operator reaches through the two armholes to blast the workpiece.
Reclaim units and dust collectors are sized for the working blast cabinet open area inside. If the reclaim unit is undersized or dirty, the dust will stay in the cabinet and make it hard to see and complete the blasting function. Or, if it’s oversized, it will suck out all of the abrasive after just a cycle or two.
