Reznor 106938 Blower Housing & Wheel

For service professionals maintaining industrial heating equipment, the Reznor 106938 Blower Housing & Wheel is the essential OEM replacement part required to restore localized airflow and thermal transfer efficiency. This assembly is specifically engineered for high-demand environments, featuring a precision-balanced 15" x 11" blower wheel with a critical 1-7/16" bore diameter. As a structural centrifugal blower assembly, it serves as the primary air-moving component for large-scale Reznor unit heaters, ensuring the heat exchanger is properly cleared of thermal energy to prevent high-limit tripping.

A failing blower housing often manifests through excessive vibration or resonant rattling, which can lead to premature motor bearing wear. Replacing the entire Reznor blower housing and wheel assembly ensures optimal static pressure and prevents the airflow imbalances common with individual component swaps. This industrial HVAC blower part is built from heavy-gauge galvanized steel to resist corrosion and maintain structural integrity during continuous high-temperature operation. Contractors should verify the shaft diameter and cabinet clearance to ensure a seamless drop-in fit for specific gas-fired unit heater models.

Key Benefits

• Precision Airflow Delivery: The balanced 15-inch wheel maintains consistent CFM, crucial for maintaining optimal combustion and heat exchange cycles.
• Heavy-Duty Construction: Reinforced steel housing resists warping under thermal stress, protecting the internal wheel from housing contact.
• OEM Compatibility: Designed as a direct-fit Reznor unit heater replacement part, reducing field modification time for 1-7/16" shaft configurations.
• Operational Quietness: Factory-balanced components minimize mechanical resonance and ductwork vibration.

Common Questions

What causes a blower wheel to go out of balance?
Accumulated particulate matter or bypass air debris can build up on the vanes, causing uneven centrifugal force. This often leads to the vibration that necessitates a full assembly replacement.

Does this assembly include the blower motor?
No, this part is the housing and wheel assembly only. It is designed to be mounted to an existing motor and shaft with a 1-7/16-inch diameter.

How do I verify if this fits my specific Reznor unit?
Confirm the bore size matches your motor shaft and cross-reference the 106938 part number with the data plate on your unit heater cabinet.
