The Reznor 170086 Fan Guard is a critical industrial safety component engineered specifically for high-capacity Reznor UDAP 300 and UDAP 400 unit heaters. Designed to meet rigid HVAC replacement parts standards, this 24-inch OEM fan guard provides a secondary barrier that protects the fan blade and motor assembly from external debris while preventing accidental contact in high-traffic mechanical spaces. Constructed from heavy-gauge steel with a durable black powder-coat finish, the Reznor 170086 ensures structural integrity under the high thermal cycles typical of industrial heating applications. As a gas-fired unit heater part, it is precision-formed to maintain optimal airflow velocities across the heat exchanger, preventing static pressure drops that can trigger high-limit switches. For contractors, this industrial heater safety guard offers a direct-fit solution, utilizing standard mounting points to secure the assembly without vibration or rattling, ensuring your equipment stays compliant with OSHA safety protocols and factory specifications during routine maintenance or unit heater repair. Key Benefits Optimized Airflow Dynamics: Engineered with precise wire spacing to ensure maximum CFM output without restricting the heater's performance. Industrial-Grade Durability: Heavy-duty steel construction with a corrosion-resistant finish designed for long-term exposure to heat and humidity. Direct OEM Compatibility: Specifically indexed for the Reznor UDAP series, ensuring exact bolt-hole alignment and a secure fit on 24-inch fan assemblies. Enhanced Safety Compliance: Reduces the risk of workplace injuries and protects expensive internal components from foreign object damage. Common Questions Is this guard compatible with models other than the UDAP 300/400? While primarily designed for the 300 and 400 series, it fits most Reznor units requiring a 24-inch diameter guard; always verify your unit's fan diameter before installation. Does the 170086 fan guard include mounting hardware? This part typically covers the guard itself; you should reuse existing factory fasteners or source appropriate grade-5 hardware for a secure mount. Can this be installed on the blower side or the discharge side? This guard is specifically designed for the intake side of the fan motor assembly to protect the rotating blades and motor from debris.
