Centrifugal Fan

Pasko Centrifugal fans are widely used in the Heating, Ventilation & Air-conditioning fields. Our products are designed to meet customers' individual specification. Whatever the requirement, be it high efficiency, low noise, clean air, handling light dust or large solid particles; a suitable centrifugal fan can be found from our range.

• Applications

  • General HVAC & R
  • Material Handling
  • Chemical Process
  • Induced Draft
  • Dust Collection
  • Dust Control
  • Pressure Blower
  • Painting plants
  • Rotogravure
  • Food industry
  • Incinerators
  • Industrial processing, etc.

The fan casings are fabricated out of continuously welded heavy gauge steel sheets with smooth exterior & interior to equalize the flow of air over the entire outlet area. Stationary vanes are used to increase efficiency with reduced turbulence & noise.


The impellers with deep, wide blades are very rigid and efficient. All impellers are precisely balanced both statically & dynamically to offer balanced rotor whirl. Centrifugal fan impeller designed by us include: backward curved, backward aerofoil, backward inclined, forward curved, radial blade etc. Standard impellers are made of mild steel. Stainless steel / FRP coated impellers can also be provided.


The shafts are liberally sized to run well below critical speed and made of high quality hot rolled steel or alloy steel depending on application.


Correct bearing design ensures long life and trouble free operation. For standard fans heavy duty double row self aligning ball bearings are used. Roller or Sleeve bearings can also be provided if needed.

Fan Drive Systems :

The fan assembly could be mounted on a wide range of driving systems to meet the desired range of performances and applications. These includes direct drive, belt drive, gear drive etc.

Fan Performance

The way Pasko fan impellers (blades or rotors) are designed, the amount of air they can move decreases as the pressure they are working against increases. The airflow vs. pressure information for a particular fan is called the fan performance data. The performance of a fan depends on the size, shape & speed of the impeller. The fan performance data is essential for selecting fans as per the desired airflow and system pressure.
