Fiberglass Tubeaxial Roof Ventilator


The PRVF fiberglass roof ventilator is designed for roof mounted exhaust applications where corrosion resistance is a primary consideration. The standard FRP resin used for the PRVF 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.
