Lennox 87A62 Blower Wheel

The Lennox 87A62 Blower Wheel is a precision-engineered direct drive blower wheel designed for high-performance airflow in Lennox residential and commercial furnaces. Featuring a 12 5/8-inch diameter and a 1/2-inch bore, this clockwise (CW) rotation wheel is constructed with 43 individual blades to maintain static pressure and balanced air distribution across your heat exchanger. As an OEM Lennox replacement part, it ensures a perfect fit on the motor shaft, reducing vibration that typically leads to premature motor bearing failure. This HVAC blower wheel is a critical component for restoring system efficiency and quiet operation. Whether you are performing a routine maintenance overhaul or emergency repair, utilizing a genuine Lennox 87A62 ensures that the CFM output matches the original factory specifications for models like the G20, G17, and G12 series. Its concave hub design provides a secure mechanical connection to the 1/2" motor shaft for dependable high-speed rotation.

• OEM Precision: Specifically balanced to eliminate "thumping" and excessive vibration during high-speed operation.
• Optimized Airflow: The 43-blade configuration is designed to maximize CFM while maintaining low decibel levels.
• Engineered Durability: Robust construction to withstand the high-torque demands of direct-drive blower motors.
• Multi-Model Compatibility: Replaces several older part numbers, including 31G66, 62A41, 71L57, and 87H81.

What is the correct rotation for this wheel?
The 87A62 is a clockwise (CW) rotation wheel when viewed from the hub side. Always verify rotation before installation to prevent airflow reversal.

Does this include the set screw?
Yes, this blower wheel comes equipped with a set screw to secure the concave hub to the 1/2-inch motor shaft.

What happens if I use an imbalanced blower wheel?
An imbalanced wheel causes shaft oscillation, which will quickly destroy the bearings in your blower motor and significantly increase noise throughout the ductwork.
