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.

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. Centrifugal fans with forward curved blades always require a spiral housing. Many industrial processes rely on high temperature process heat. In the example shown below the fan rotates in a clockwise direction.

High temperature process airstreams require specially designed centrifugal fans that can handle extremely high temperatures. 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. 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. Along with the radial paddle wheel fan the forward curved fan is one of the select designs that can take the heat.

Backward curved centrifugal fans. A forward curved centrifugal fan is characterised by its cylindrical shape and lots of small blades on the circumference of the impeller. They re also a lot more energy efficient.
