Fan Type: DC Centrifugal Fan Backward Curved 24VDC 48VDC

DC centrifugal fans with backward-curved blades are used primarily for intake suction. Since most of the pressure build-up takes place in the impeller, there is generally no need for a scroll housing. The centrifugal fans have very good hydraulic efficiency and are ideally suited for high pressures. The centrifugal fans are used in applications such as central air conditioning units or building ventilation systems.
