Impeller type


Backward Curved High Pressure Composite Fans, SWSI


The BCSF Centrifugal Composite Fan is a backward curved industrial fan designed for handling particulate-free, corrosive or caustic air in high pressure applications where conventional steel and stainless steel fans would corrode. Typical industries that utilize this style of fan include pulp and paper, steel processing, petrochemical plants and wastewater treatment facilities. All of the parts that are exposed to the airstream are constructed of high-quality corrosion resistant materials to avoid material breakdown from most chemicals. The BCSF also features a wide impeller and housing, producing a high volume of air at a lower velocity.

Sizes (impeller diameters)

  • 16.5 to 60 inches (420 mm to 1,525 mm)


  • Airflow to 151,000 CFM (256,500 m3/hour)
  • Static pressure to 34 inches w.g. (8,450 Pa)


**Note : BCSF model will be imported from Twin City Fan & Blower.
