Centrifugal Fans (SWSI & DWDI Type)

Centrifugal Fans SWSI Type

SWSI Type

These are single width single inlet and limit load type centrifugal fans suitable for high volumetric flow rate, low pressure, low speed & low level noise applications viz. ventilation, air conditioning, air pressurization and evaporative cooling/air washer systems. For higher impeller dia, fan speed recommended is less for better performance.

These centrifugal fans are supplied in direct drive or V-belt drive arrangement along with reputed make motors and various accessories to suit the operating conditions.

These fans generally operate at ambient temperature and pressure. Their MOC is CS or Aluminum coated with standard or epoxy paint depending on the corrosive conditions in the surroundings.
