Centrifugal Extraction Fans for Corrosive Applications
December 30, 2023

The SEAT fan range incorporates cowls with centrifugal impellers that are made of polypropylene which is resistant to most chemicals used in laboratories. These chemicals include strong mineral acids, caustic and ammoniac solutions, inorganic saline solutions and organic and detergent products. Where metallic fans are prone to corrosion, the long-lasting, SEAT fan product will continue to function flawlessly.

There are 3 types of SEAT fans with a range of sizes and mounting arrangements to suit most applications and installation types.

Suitable applications

  • Laboratories
  • Water treatment plants
  • Hospitals
  • Electroplating facilities
  • Colleges and universities

SEAT Series

Designed to exhaust fumes from corrosive environments such as laboratories, fume cupboards, battery rooms and chemical plants. Includes a high density, UV treated polypropylene housing and impeller to ensure maximum protection against acids and corrosion.

  • Cowl rotates to 8 discharge positions by 45° increments
  • Stainless steel hardware
  • Forward curved centrifugal impeller
  • Direct drive, asynchronous motor, single or three phase, IP55
  • Explosion proof motors available
  • Five models available with air flows from 50 to 9000 m3 /h
  • 10 to 1400Pa total pressure

JET Series

The roof mounted Jet Series fans with vertical discharge are suitable for highly corrosive applications such as laboratory exhaust or the chemical industry. JET fans generate a high plume to ensure maximum dilution of gases in the environment. They include a high performance centrifugal impeller and a fully enclosed motor that is protected from the corrosive airstream.

  • High density, UV treated polypropylene housing and impeller
  • Stainless steel hardware
  • Forward curved centrifugal
  • Direct drive, asynchronous motor, single or three phase,
  • Explosion proof motors available
  • Three models with air flows from 300 to 3500 m3 /h
  • 80 to 800 Pa total pressure

STORM Series

The STORM Series is a centrifugal type medium pressure fan suitable for operation in corrosive applications such as fume capture arms, gas scrubbers or chemical cabinets.

  • Cowl rotates to 8 discharge positions by 45° increments
  • High density, UV treated polypropylene housing and impeller (STORM 10 Polyethylene)
  • Stainless steel hardware
  • Forward curved centrifugal impeller
  • Direct drive, asynchronous motor, single or three phase, IP55
  • Explosion proof motors available on request.
  • Four models with air flows from 25 to 1800 m3 /h
  • Up to 3000 Pa total pressure
