Perma Vent®


RPC’s Glass Reinforced Plastic (GRP) Vent Shafts – Perma Vent® are chemically and structurally engineered with the optimal balance of resin and glass fibre for resistance to a wide range of acids, alkalis, solvents and corrosive fumes.

In addition to their resistance to corrosion, pitting and scaling, Perma Vent® is immune to virtually all bacteriological corrosion, will not rust and does not require any form of cathodic protection. A surface coating applied during manufacture ensures a long life, even in Australia’s most demanding climatic conditions. Once installed Perma Vent™ is virtually maintenance free.
