Centrifugal HAVC Fan Blower Wheel
The HVAC blower wheel is a component of the blower motor, and its job is to move large volumes of air through the duct system. If the blower wheel gets dirt or grease built up, it can slow down the wheels rotation and reduce the amount of air your blower motor is capable of moving through your home.
Centrifugal fans are used when airflow is needed for aspirating, cooling, ventilating and conveying. They are constructed as a fixed drum shape with a number of fan blades that rotate and blow the air or gas from one place to another. We stock a range of centrifugal fan wheels in case you need to replace your current one.
