Description
The Lennox 31K74 is an essential part of the blower motor in HVAC systems. It is simply an 18-inch long and 1-inch diameter metallic structure made from 1045 or C45 steel. This shaft is essential in that it transmits rotational force from the motor to the blower wheel. The blower wheel then transmits this amount of power to blow air within the heating and cooling system thereby circulating well-conditioned air within the house. It uses a standard 24V power source and can be used with systems that have 50 or 60 Hz frequency.
