Impeller Type


Fiberglass Radial Blade
Centrifugal Fan


The RBF fiberglass fan offers superior corrosion resistance to gases, fumes and vapors. The RBF’s fan housing features a solid FRP hand lay-up construction utilizing corrosion grade flame retardant vinyl ester resin. A glass veil is standard for airstream surfaces providing a resin rich liner to maximize chemical resistance.

The standard resin used for the RBF 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.
