NRF 47326 Fan, radiator

Overview of the NRF 47326 Radiator Fan

The NRF 47326 is a high‑performance radiator fan designed to keep automotive engines operating within optimal temperature ranges. Originally engineered for use in compact and mid‑size vehicles, this fan delivers reliable airflow while maintaining low noise levels and energy efficiency.

Key Design Features

• Durable Construction: The fan housing is made from reinforced aluminum alloy, providing resistance to corrosion and mechanical stress. The internal impeller blades are forged from high‑strength steel, ensuring longevity even under continuous operation.
• Optimized Blade Geometry: Each blade features a precisely calculated pitch that maximizes airflow while minimizing turbulence. This design reduces the fan’s acoustic signature, making it suitable for vehicles where cabin noise is a concern.
• Compact Footprint: With dimensions of approximately 120 mm × 120 mm × 60 mm, the NRF 47326 fits easily into tight engine bay spaces without compromising cooling performance.
• Low‑Voltage Compatibility: The fan operates on a standard automotive 12 V DC supply, making it compatible with most vehicle electrical systems without requiring additional voltage regulation.

Performance Specifications

Installation Guide

Installing the NRF 47326 is straightforward, but attention to detail ensures optimal performance and longevity.

1. Remove Existing Fan: Disconnect the power connector, unscrew mounting bolts, and carefully detach the old fan from the radiator assembly.
2. Prepare Mounting Surface: Clean the mounting area to remove debris or corrosion. Verify that the surface is level; if necessary, use a shim to correct any misalignment.
3. Mount the Fan: Align the fan’s mounting holes with the prepared surface and secure it using the supplied bolts. Tighten evenly to avoid warping.
4. Connect Power: Attach the fan’s wiring harness to the vehicle’s cooling system controller or directly to a suitable power source, ensuring correct polarity.
5. Test Operation: Start the engine and observe the fan’s operation. Verify that it spins smoothly, reaches the expected speed range, and does not produce excessive vibration.
