Impeller type


Backward Curved High Volume /
Pressure Fan SWSI


The BCS Backward Curved High Volume/Pressure Fan is designed for handling relatively clean air in high pressure applications. Typical applications include combustion air, product cooling, moisture blow-off, forced draft on fluid bed boilers and induced draft after baghouse process blowers.

The BCS impeller features heavy-gauge steel construction and a non-overloading impeller design, suitable for applications requiring large volumes of air at moderate to high pressures. All impeller are statically and dynamically balanced to grade G6.3 per ANSI S2.19 for smooth operation prior to assembly of the fan, followed by a final balance of the entire rotating assembly.
