Forward Curved Centrifugal Fan Definition

Applications of fan types.

Forward curved centrifugal fan definition. Along with the radial paddle wheel fan the forward curved fan is one of the select designs that can take the heat. These fans are for low to medium static applications. A double outlet centrifugal fan has a volute with two outlets. Forward curved centrifugal fans.

Each fan system has different types of wheels or impeller types. These fans increase the speed and volume of an air stream with the rotating impellers. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink. Backward curved centrifugal fans are uncommonly shaped blades which can be curved or straight make these fans excellent for high volumes of airflow and variable resistance.

A central unit in such industries supplies conditioned air to various enclosures through different ports. Centrifugal impeller styles forward curve sometimes referred to as a squirrel cage fan forward curve fans are used in most residential and light commercial hvac equipment. Forward curved squirrel cage fans are the prime candidates for such applications. Automobile ventilation is an example where such fans serve both right and left sides of the cabin.

A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Many industrial processes rely on high temperature process heat. Centrifugal fans use the kinetic energy of the impellers to increase the volume of the air strea. Such a fan is also called a blower fan biscuit blower or squirrel cage fan.

In the example shown below the fan rotates in a clockwise direction. 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. High temperature process airstreams require specially designed centrifugal fans that can handle extremely high temperatures. These centrifugal fans are ideal for those companies looking for fans that can deliver medium to high airflow in their facilities.

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.
