Exhaust hoods serve a wide variety of industrial processes where toxic contaminants are present. Hoods are designed to capture fumes and funnel them into an exhaust system where they can be removed from human and environmental contact. These tapered rear exhaust fume hoods are fabricated of corrosion resistant polypropylene which offers excellent resistant to a wide range of chemicals. Hoods are made to rest on the rear edge of tanks from which harmful fumes may emanate. When connected to an exhaust blower system, the hoods direct a stream of air across the top of the tank away from the operator. Temperature range: 40°F to 200°F. Prices are for single slots in hood.
