CFM A15 compressed-air vacuum is made to safely collect toxic and nuisance materials, including ultra-fine powders, dust, and debris, without electricity. The compact vacuum is ideal for metalworking, automotive, woodworking, fabrication, and other manufacturing applications where electricity is either unsafe or unavailable. The vacuum's main filter has a large surface area, which helps prevent premature filter clogging and the associated maintenance. An external handle enables users to shake the main filter free of clogging dust without opening the vacuum. Additionally, the vacuum's 6.6-gal wheeled collection container is easy to remove, lift, carry and empty for swift waste disposal.
