Forward Curved Blades Centrifugal Fan

Centrifugal fans single inlet the scroll housing of single inlet centrifugal fans is open on one side.

Forward curved blades centrifugal fan.

They re also a lot more energy efficient. One of the first things you ll notice when you compare backward curved centrifugal fans to forward curved ones is that they re a lot heavier than their counterparts. Centrifugal fans with forward curved blades always require a spiral housing. 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.

Backward curved centrifugal fans. Many industrial processes rely on high temperature process heat. The centrifugal fans with forward curved blades 2l 90 o are designed due to the small dimensions and good static pressure characteristics of fans and such a recommendation refers to the fans. Their characteristic features are a low noise level relatively small air flow with a high increase in static pressure and space saving application.

Forward curved centrifugal fans are more cost effective than backward curved centrifugal fans though and have become popular in industries like the medicinal industries since they don t accumulate chemicals and other debris on their blades. 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.
