Forward Curved Centrifugal Fan Design

Centrifugal fans with forward curved blades centrifugal blowers are used in all sorts of applications demanding a low noise level a relatively low air flow with high static pressure increase and a space saving design.

Forward curved centrifugal fan design.

High temperature process airstreams require specially designed centrifugal fans that can handle extremely high temperatures. In the example shown below the fan rotates in a clockwise direction. Along with the radial paddle wheel fan the forward curved fan is one of the select designs that can take the heat. A forward curved centrifugal fan is characterised by its cylindrical shape and lots of small blades on the circumference of the impeller.

108mm 120mm 133mm 140mm 146mm 160mm and 180mm. Centrifugal fans with forward curved blades always require a scroll housing see figure 2 16. They utilize a much higher rpm than the rpm found in backward curved centrifugal fans but it s worth noting that they also usually have a lower efficiency. Their characteristic features are a low noise level relatively small air flow with a high increase in static pressure and space saving application.

Many industrial processes rely on high temperature process heat. Diameter of forward curved impellers. Heko forward curved centrifugal fan series is with ec and dc input. Forward curved centrifugal fans.
