Medium pressure centrifugal fans with reinforced housing

Suitable for Category 3 Corrosive Applications

The PREXTUR range of medium pressure centrifugal fans feature carbon laminated steel housing and offer enhanced corrosion protection with its powder coating polyester resin. With a corrosive rating of C3, the PREXTUR range are suitable for indoor applications with high humidity and some air pollution, exterior urban and industrial atmosphers, areas with moderate sulphur dioxide pollution or coastal areas with low salinity. Enhanced paint protection options are also available on request. 

Ideal for Moving Clean or Dusty Air in Medium Pressure Applications

PREXTUR fans are designed for the transportation of clean or dusty air in medium pressure applications such as paint booths, food processing, incineration, odour control, extraction of smoke and the manufacture and treatment of chemical products.

Available Fan Types
