Vacuum with no moving parts or electricity
February 2006
Pneumatics & Hydraulics
Exair's Chip Vac picks up wet or dry chips and delivers them into an ordinary 210 litre drum. The Chip Vac is used to clean chips from fixtures, floors and work surfaces of machine centres, lathes, saws, mills and other industrial equipment. A 30% increase in vacuum makes it Exair's most powerful Chip Vac ever.
The compressed air operated Chip Vac is an industrial duty vacuum designed specifically for vacuuming chips. It creates a cyclonic action that lifts metal, wood or plastic chips into a 210 litre drum. The 0,1 micron filter bag to keep surrounding air clean traps dusty materials such as absorbents.
Electrically operated 'all purpose' vacuums are not designed for use in industrial environments and as a result motors wear out quickly and impellers clog. Chip Vac has no moving parts to wear out or break ensuring long life. Sound levels are half of what electric vacuum is.
Chip Vac's lever lock drum lid fits an ordinary open top 210 litre drum. In less than a minute, the Chip Vac can be removed and easily placed onto another drum to keep different material separate for re-cycling. Constant heavy lifting and dumping of vacuum cleaner tanks is eliminated since all chips are vacuumed directly into the 210 litre drum.
How the Chip Vac Works
Compressed air, normally at 550 to 690 kPa, flows through the inlet (1) into an annular plenum chamber (2). It is then injected into the throat through directed nozzles (3). These jets of air create a vacuum at the intake (4), which draws material in and accelerates it through the unit (5). An elbow at the exhaust (6) directs the air in a cyclonic motion against the side of the drum. Chips and other particulate drop to the bottom of the drum. The air flow exhausts through the port in the drum lid (7). Airborne particulates are trapped by the filter bag.
