Carrier KR11AZ712 Blower Pulley

The Carrier KR11AZ712 Blower Pulley is a crucial part for normal airflow in Carrier HVAC system. This 6.5-" diameter pulley is made of durable nylon plastic with a 1-" bore diameter to fit on motor shaft. The motor shaft of the KR11AZ712 pulley is either mechanically coupled to a compatible 4L, A, or B type belt, or connected directly to the blower fan with a similar 4L, A, or B type belt, in order to transmit rotational motion from the motor to the blower fan. This transfer of power creates airflow throughout the HVAC system, and distributes conditioned air throughout your home.
