Description
The Carrier LA21RB552 is an Inducer Blower Wheel, which is a spare part used in most heating and cooling systems but mostly in furnaces. This essential component is a fan located inside the inducer housing assembly, a small fan blade that rotates at high speed. Constructed from high-strength steel this component is turned on in an anti-clockwise direction directing combustion gases and air to be drawn into the furnace. Ventilation is a factor that helps in the efficiency and safety of operation in the Carrier HVAC system to keep the airflow properly. The blower wheel has a diameter of 6-1/4″ and a width of 6-3/10″ with a bore diameter of 5/16″ to fit the motor shaft.
