AC Backward Curved Centrifugal Fan BMF400

1.Centrifugal fan with backward curved blades is mainly used for air intake. Since most of the pressure buildup occurs in the impeller, a vortex housing is generally not required. Centrifugal fans have excellent hydraulic efficiency and low noise levels, making them ideal for high pressures.

2.Application: centrifugal fans are used in applications such as central air conditioning installation or ventilation systems of buildings.

3.Customized manufacturing available
