Bifurcated Fans

Also known as ‘bif’ fans are inline axial flow fans where the motor has been taken out of the airstream which allows the fan to operate at higher temperatures. They are suitable for medium to high volume applications with low-pressure development. Various makes and sizes available upon request.


Bifurcated fans are ideal for exhausting or recirculating fumes, gases and hot air up to 80°C (NT) or 200°C (HT) continuous operation. Compared to direct drive axial types, bifurcated fans have the following advantages:

  • Higher temperature ratings
  • Isolation of motor from heat or contaminants in the airstream
  • Easier maintenance

Bifurcated axial fans are used in situations where it is important that the motor is kept out of the airstream (though with suitable access to ambient air) due to the type or temperature of the gases/fumes involved.
