The Industrial Downdraft Bench effectively captures and extracts fumes, dust, and smoke at the work surface level. This safety engineering control helps protect the operator’s breathing zone and surrounding environment from hazardous airborne contaminants. Within the perforated workspace of 40” width by 22” deep, the powerful industrial air cleaner pulls fumes and particulate into the filtration chamber. The Industrial Downdraft Bench comes standard with HEPA filtration offering up to 99.97% efficiency on particles 0.3 microns and larger. The air cleaner provides up to 700 CFM of air volume. Other filtration options include ASHRAE filtration (up to 95% efficiency on particles 0.5 microns and larger) for particulate removal, and heavy-duty Activated Carbon and Specialty Blended Filter Media (acid gas, ammonia, aldehyde, and mercury) for chemical fume control.
