Impeller Type


Fiberglass SW Airfoil Fan, BIA Impeller


The SWCBF fiberglass fan is constructed for durability and resistance to most chemicals. All airstream parts are constructed of fiberglass reinforced plastic and mounted on an all-welded, heavy-gauge steel base. Features Aerovent’s BIA backward inclined airfoil blades offering a power limiting characteristic, high operating efficiency and low noise levels.

The standard FRP resin used for the SWCBF is resistant to a large variety of alkalis and other chemical agents. When a corrosion resistant fan is required to withstand chemicals that attack glass or polyester resin, special plastic and reinforcing material can be supplied.
