Along with the radial paddle wheel fan the forward curved fan is one of the select designs that can take the heat.
Forward curved centrifugal fan design.
Dc forward curved centrifugal fan ΓΈ120 83mm with brushless dc motor.
Centrifugal fans with forward curved blades always require a scroll housing see figure 2 16.
High temperature process airstreams require specially designed centrifugal fans that can handle extremely high temperatures.
A forward curved centrifugal fan is characterised by its cylindrical shape and lots of small blades on the circumference of the impeller.
In the example shown below the fan rotates in a clockwise direction.
Heko forward curved centrifugal fan series is with ec and dc input.
All size centrifugal fans are motorized by 3 core ec brushless external rotor motor.
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.
108mm 120mm 133mm 140mm 146mm 160mm and 180mm.
These centrifugal fans are ideal for those companies looking for fans that can deliver medium to high airflow in their facilities.
Forward curved centrifugal fans.
Many industrial processes rely on high temperature process heat.
