Heavy-duty dry vacuum system is powered by compressed air and attaches to the included drum. It is quiet at 82 dBA (half the noise of electric vacuums). Surrounding air is kept clean by the 0.1 µm filter bag that traps particles when vacuuming dusty materials. It does not have any motors or impellers that could clog or wear out. It is supplied with a 10' (3 m) static resistant hose; 20' (6 m) compressed air hose; shutoff valve; pressure gauge; heavy-duty tools; drum dolly and 30, 55 or 110 gal drum.
