108mm 120mm 133mm 140mm 146mm 160mm and 180mm.
Forward curved centrifugal fan design.
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.
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.
Dc forward curved centrifugal fan ø120 83mm with brushless dc motor.
All size centrifugal fans are motorized by 3 core ec brushless external rotor motor.
In the example shown below the fan rotates in a clockwise direction.
Diameter of forward curved impellers.
Many industrial processes rely on high temperature process heat.
Along with the radial paddle wheel fan the forward curved fan is one of the select designs that can take the heat.
High temperature process airstreams require specially designed centrifugal fans that can handle extremely high temperatures.
Forward curved centrifugal fans.
Centrifugal fans with forward curved blades always require a scroll housing see figure 2 16.
