With this fume hood, exhaust air volume is equal to the auxiliary supply air—therefore there is no required air from the laboratory space. This can be achieved with the sash half-open and a face velocity of 100 feet per minute. Auxiliary air fume hoods are available in 4′, 5′, and 6′ widths. All electrical components and services are UL and CSA listed. Supply air ducting and remote blower are required. Shown with optional service fixtures, plumbing and electrical, airflow monitor, and work surface.
