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.
