AXIAL FLOW FANS

  • To achieve high efficiency, fans have a defined hub ratio 71 to 25 for given capacity, pressure and speed.

  • Impeller blades are adjustable type and can rest at designed angle to suit the system resistance.

  • Fan can run in parallel to suit capacity and in series for higher pressure.
  • Impeller is made of aerofoil profile from cast aluminium alloys.
  • Bifuracated type fans are available .
  • Capacity          : Upto 3,00,000 m3 /hr
  • Pressure          : Upto 100 mm of WG.


The Axial Fans are aero-dynamically designed to cover wide range of capacity and pressure. Hub ratio is varied from propeller type low pressure to tube axial medium pressure to vane axial high pressure. The pitch angle of the blades are varied at rest to suit system resistance.
