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.
Forward curved centrifugal fan design.
Diameter of forward curved impellers.
Centrifugal fans with forward curved blades always require a scroll housing see figure 2 16.
Heko forward curved centrifugal fan series is with ec and dc input.
A forward curved centrifugal fan is characterised by its cylindrical shape and lots of small blades on the circumference of the impeller.
Many industrial processes rely on high temperature process heat.
These centrifugal fans are ideal for those companies looking for fans that can deliver medium to high airflow in their facilities.
