The Porta Air™ cartridge system from Air Quality Engineering Inc. is the perfect portable air cleaner for welding smoke grinding dust, plastics machining and other fine particulate matter generating applications. The Porta Air™ media air cleaner doesn’t include reverse pulse jet capabilities and is ideal for applications where the user doesn’t want the possibility of re-entraining hazardous particulate back into the clean air stream or is interested in the most economical cartridge system solution for their air quality needs. Porta Air™ units may be outfitted with post-HEPA filters, lighted capture arm hoods and specialty cartridge media filters.
