Reznor 170085 Fan Guard

The Reznor 170085 Fan Guard is a critical genuine OEM safety component specifically engineered for Reznor HVAC equipment. This 20-inch fan guard is designed to meet factory airflow specifications while providing a rigid barrier for the fan assembly. In the field, using a unit heater fan guard that exactly matches original equipment dimensions is essential for maintaining both OSHA compliance and system efficiency. A loose or non-spec guard can lead to harmonic vibration or restricted static pressure, which prematurely wears the motor. This direct-fit replacement ensures the propeller is shielded without causing the turbulence often associated with universal aftermarket cages. For contractors performing preventative maintenance or repairs on gas-fired unit heaters or air handlers, installing this OEM 170085 part ensures that the motor's cooling capacity is unhindered and the safety perimeter remains intact.

Key Benefits for the Contractor

• Direct OEM Compatibility: Eliminates field modifications and ensures mounting holes align perfectly with the fan shroud.
• Optimized Static Pressure: Precision-gauged wire spacing allows maximum cubic feet per minute (CFM) while maintaining unit heater safety standards.
• Industrial Durability: The heavy-duty construction is built to withstand the thermal expansion and contraction cycles of commercial heating environments.
• Simplified Installation: Standard 20-inch sizing fits specific Reznor F, FE, B, and BE series models reliably.

Common Questions

Is the Reznor 170085 a universal part?
No, this is a genuine Reznor 170085 replacement tailored for their 20-inch fan configurations. Always verify your model and serial number to ensure the fan diameter and mounting pattern match your specific unit heater.

What happens if I operate the unit without this fan guard?
Operating without a fan assembly guard creates a significant safety hazard and may violate local mechanical codes. Additionally, the guard can provide structural integrity to the rear of the fan assembly on certain models.

Can this guard be used on other 20-inch fans?
While it is a 20-inch diameter guard, the mounting bracket locations are specific to Reznor HVAC equipment. We recommend using it only for professional HVAC replacement parts servicing on compatible Reznor units.
