Carrier KR52BH615 Blower Pulley

The Carrier KR52BH615 Blower Pulley is an essential part of Carrier HVAC systems which is mainly used to transfer rotational torque from the motor to the blower fan. This is normally manufactured utilizing cast iron or steel material and the part contains a machined groove to accommodate the blower fan belt. The position of this part is to change the fan speed through changing the belt tension. In the case of a variable diameter pulley, this translates as an increase or decrease of the circumference of the belt in contact and directly affecting the fans rotation. This speed control is desirable when controlling the air flow and regulating the established temperature in the conditioned zone space.
