Environmental control booths, sometimes known as ECB, dust booths, dust control booths or clean air booths, provide containment of dust and particles and other contaminants that can be harmful to workers and to equipment. They offer controlled air circulation and a dust collector to remove contaminants and they offer optimal environmental conditions inside and outside the working area. Dust booths with wet filter dust collection systems provide safe collection of potentially explosive dusts such as aluminum and titanium. Air Purification, Inc. offers NFPA and OSHA approved environmental control booths.
