Portable Air Scrubbers are ideal for high-production cutting of metal drywall studs, pipe and other metal components. Portable air scrubbers utilize four stages of progressively efficient filters to remove particulate and gaseous contaminants & odors from the air: These portable air scrubbers can be utilized to continuously filter and recirculate air within a local area to provide general air cleaning. These scrubbers filter the air inside the containment area and exhausts filtered air outside the containment area through flexible ducting. They provide high performance filtration of airborne contaminants in a wide range of applications, including mold abatement & disaster restoration as well as construction, renovation and industrial operations. Portable air scrubbers are also utilized for filtering contaminated air and preventing the spread of airborne contaminants such as mold spores. Portable air scrubbers carry air filtration to an even higher level than negative air machines by utilizing more powerful blowers that pull high volumes of air through four stages of filtration. They can be operated using three different methods such as recirculation, negative pressure and air cleaning in remote areas.
