Lennox 70W42 Blower Housing
The Lennox 70W42 Blower Housing is a critical OEM replacement part engineered for precise airflow management in high-efficiency furnace and air handler assemblies. Built to fit a flat-sided 11-inch by 11-inch configuration, this housing ensures the proper static pressure required for optimal heat exchange and cooling performance. As a veteran technician knows, maintaining the integrity of the centrifugal fan enclosure is vital to preventing surging and excessive vibration, which can lead to premature motor or wheel failure. This structural component is crucial for Lennox HVAC systems like the EL195 and EL296 series, providing the rigid mount needed for blower motor alignment and blower wheel centering.
When performing a swap, this Lennox 70W42 housing provides a direct fit for the LB-94726X series, reducing labor time during HVAC repair by eliminating the need for field modifications. Replacing a rusted or warped furnace blower housing restores factory-spec CFM across the evaporator coil or heat exchanger, protecting the internal components from overheating. This housing is designed to meet the rigorous demands of residential and commercial HVAC environments, ensuring reliable air distribution and quiet operation throughout the system's service life.
Key Benefits:- OEM Compatibility: Specifically designed for Lennox EL195, EL296, and EL180UH series units to ensure a perfect mechanical fit.
- Heavy-Duty Construction: High-grade galvanized steel resists corrosion and maintains structural rigidity under high static pressure.
- System Efficiency: Restores factory-designed airflow patterns, which is essential for maintaining SEER and AFUE ratings.
- Vibration Reduction: Precision-stamped housing minimizes turbulence and mechanical noise during the blower motor cycle.
Does this housing include the blower wheel or motor?
No, the Lennox 70W42 is the housing assembly only. You must transfer your existing blower wheel, motor, and cut-off plate, or purchase them separately if they are damaged.
How do I ensure the blower wheel is correctly balanced after installation?
Always center the wheel within the housing before tightening the set screw. Ensure the flat portion of the motor shaft aligns perfectly with the set screw to prevent slipping and rotational imbalance.
Will this fit 80% AFUE Lennox furnaces?
This housing is compatible with several 80% models, including the EL180 series, but you should verify your specific cabinet size and LB-94726X cross-reference before installation.
