The Auxiliary-Air Fume Hood reduces the loss of expensive tempered air from the laboratory. Ideal for laboratories with inadequate make-up air supply.
Recommended when there is insufficient air available in the lab to support the volume of air required to maintain a desired face velocity. Auxiliary-Air Hoods have a supply plenum to which ducting connects to a supply blower.
In addition to supplementing air to fume hoods when there is less than sufficient air available in the lab, Auxiliary Air fume hoods reduce the amount of expensive air-conditioned or heated air that exhausted to the outside. Between 50% to 70% of the exhaust can be supplied from outside the lab.
