Airfoil Impellers Wall Fans are designed and built around our standard panel fan, providing near maintenance-free operation. Available in both direct-drive and belt-drive configurations, our wall fans come standard with three phase high efficiency motors. Rain hoods are available for supply fans, and optional aluminum back draft dampers -- both gravity- and motor-actuated -- will provide rain-tight protection for exhaust fans.
Standard housings are fabricated using steel, but are also available in aluminum and stainless steel construction. Additionally, steel housings come standard with an enamel finish, with optional epoxy and hot dip galvanized finishes available.
