The Packard 5412 is a professional-grade 9W 115V evaporator fan motor engineered for demanding commercial refrigeration applications. This unit bearing fan motor features a standard 51 frame and operates at 1550 RPM, making it a drop-in replacement for the GE 5412 and several Mars motormate equivalents. Designed for continuous air over (CAO) duty, the motor utilizes improved permanent lubrication and specialized sleeve bearings to ensure long-term reliability in walk-in coolers, display cases, and reach-in freezers. Its all-angle mounting capability provides versatility for vertical or horizontal installations, while the single-speed CCW rotation ensures precise airflow across the coil. With internal impedance or overload protection and 50/60 Hz compatibility, this cast iron refrigeration motor handles voltage fluctuations effectively, reducing field failures in high-cycle environments. This is a standard 1/4-20 threaded shaft component built for consistent performance in low-temperature and medium-temperature refrigeration systems. Direct OEM Replacement: Seamlessly replaces GE 5412 and Mars 9-watt unit bearing motors with a standard 51 frame footprint. All-Angle Operation: Durable unit sleeve bearings allow for mounting in any orientation without compromising life expectancy. Enhanced Lubrication: Improved permanent oiling system minimizes friction and extends the interval between maintenance cycles. Rugged Protection: Features impedance or thermal overload protection to prevent winding burnout during stalled rotor conditions. Quiet Performance: Optimized for low-vibration operation in customer-facing display cases and quiet walk-ins. Common Questions Is the Packard 5412 compatible with both 50Hz and 60Hz power? Yes, this unit is rated for both 50 and 60 Hz, allowing it to maintain performance across different regional power standards common in commercial refrigeration. Can this motor be used in high-moisture evaporator environments? The Packard 5412 is a cast iron unit bearing motor designed specifically for refrigeration; however, it must be installed in a continuous air over application to maintain proper operating temperatures. What rotation is required for my fan blade? This motor is fixed CCW (counter-clockwise) rotation from the lead end. Always verify your fan blade pitch to ensure proper airflow direction before installation. Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
