Description
The York S1-3L220 Fractional Drive V-Belt HP 3L220 is used to transmit rotational power between motor and blower pulleys. It operates as part of the drive assembly in air handling units, where it connects the motor shaft to the fan or blower shaft to maintain controlled airflow. The belt is specified for light-duty HVAC systems equipment and supports stable mechanical coupling under continuous operation. It is installed in commercial heating and cooling systems, particularly in air handlers and rooftop units, where it ensures consistent blower performance and system efficiency through mechanical power transfer.
