Backward Curved Centrifugal Fan. Longwell is a manufacturer of ac / dc / ec backward curved centrifugal fan in china. These compact and rugged fans are ip20/23/44 rated with an operating life of 40,000 hours.

The benefit of using a single inlet forward curved motorized impeller is that it has a steep fan characteristic. Diameter of backward curved impeller is 133mm, 175mm, 190mm, 220mm, 225mm, 250mm, 280mm, 310mm, 355mm and 400mm. Two of the most common types of blades are forward curved (also known as.

Blades Are Represented In Fig.7.
For a given rotational speed, an impeller with curved shroud plate allows to extend the fan’s ability to work at higher inlet volume flow rate. Udci offers the backward curved centrifugal fans in multiple sizes, arrangements, construction classes, impeller, and housing widths. Backward curved centrifugal fans typically have fewer impeller blades which are facing away from the direction of rotation of the impeller.
The Series 41P Fan Has The Same Airstream Components As The Series 41 Fan, In A Compact Packaged Class Ii Design.
Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; Each wheel type has its own application range and limits. The series 41u fan is a utility set version of the series.
Two Of The Most Common Types Of Blades Are Forward Curved (Also Known As.
Another important design feature is the position of the motor. They will sometimes cost a little more than other options on the front end. A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid.
