The RFE and FPB are resistant to attack from most chemicals and are ideally suited to applications in the chemical, pulp and paper, wastewater-treatment, fertilizer, pharmaceutical, and metal plating industries. Specifically, the RFE is designed for exhausting moderate volumes of highly corrosive fumes at moderate pressures.

Typical applications include laboratory fume hoods, small plating and pickling operations, etching processes, and chemical-fume scrubbers. The FPB is designed for low volumes at high pressures. Typical applications include pulp and paper processes, chemical-fume scrubbers, and soil remediation.
