How The Heavy Duty HEPA Vac™ Works
Compressed air, normally 80-100 PSIG (5.5 - 6.9 BAR), 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, accelerates it through the unit (5), and directs it to the bottom of the drum. The airflow passes first through the pre-filter and then through the 0.3 micron HEPA filter, trapping airborne particles. It then exhausts through the vent in the drum lid (6). The Heavy Duty Dry Vac unit (5) and vacuum tools (7) are built to resist wear.
