NON-METALLIC VENTS
Fiberglass Reinforced Plastic (FRP) Thermoplastic Resin Vents (PVC, Polyethylene, Polypropylene, and PVDF)

 

For those instances when chemicals being stored are particularly aggressive or corrosive to vents of metal construction, Protectoseal offers a full line of pressure and/or vacuum relief devices manufactured from nonmetallic materials. These vents often provide superior service life and may be considered as an alternative to the use of vents protected by coatings, or vents manufactured from exotic metals.

FIBERGLASS REINFORCED PLASTIC (FRP) vents are exceptionally rugged. The unique one-piece housing and hand lay-up construction eliminates seams, insuring integrity of the vent throughout a long service life. Glass reinforcing fibers, coupled with careful choice of plastic resin, provides maximum resistance to the effects of strong corrosive media. Standard resins of construction include Derakane 470®, Derakane 411® and Furan.
