Maintain peak airflow and system static pressure with the Reznor 222465 Fan Blade, an OEM replacement part specifically engineered for high-performance Reznor unit heaters. Designed for industrial HVAC performance, this high-grade metal alloy fan blade is a critical component for Model MAPS III and IV Modular Air Processing Systems, typically utilized in 248 through 482 MBH configurations including RDB, REDB, and RDDC models. As a veteran-grade Reznor heating unit part, it features an enhanced aerodynamic pitch to maximize CFM output while reducing motor torque load, ensuring efficient heat exchange across the coil. This HVAC ventilation fan blade is precision-balanced to eliminate vibration and bearing wear on the motor shaft, making it the standard choice for professional contractors during seasonal maintenance or emergency repairs. Its corrosion-resistant finish is built to withstand the rigors of commercial air handling environments, providing reliable service life in commercial heating applications without the noise issues associated with aftermarket alternatives. Key Benefits OEM Compatibility: Specifically engineered for Reznor MAPS III/IV Modular Air Processing Systems and MBH series heaters for a drop-in fit. Optimized Airflow: Precision-balanced blade design enhances airflow efficiency and manages static pressure across the heat exchanger. Durable Construction: Fabricated from high-grade corrosion-resistant metal to handle high-demand industrial environments. Reduced Vibration: Precision manufacturing ensures smooth operation, protecting the fan motor from premature bearing failure. Common Questions Which Reznor models use the 222465 fan blade? This blade is primarily used on the MAPS III and IV Modular Air Processing Systems, including 248, 262, 272, 288, 354, 370, 468, and 482 MBH units (RDB, REDB, RDDB, RDC, REDC, RDDC). Is professional installation required for this part? Yes, for safety and technical accuracy, it is highly recommended that a licensed HVAC technician performs the replacement to ensure proper balancing and motor alignment. Can I use an aftermarket blade instead of the 222465? While universal blades exist, the 222465 is a precision OEM replacement. Using non-specified blades can lead to insufficient airflow, higher energy costs, and potential unit overheating. This item is not eligible for free shipping.
