NRF 47319 Fan, radiator

Overview

The NRF 47319 Fan, also known as the radiator fan for motor cooling, is a high‑performance component designed to keep engine temperatures within safe limits. It is engineered with precision airflow dynamics and robust construction to withstand the demanding environment of automotive radiators.

Design & Construction

The fan features an aerodynamic blade profile that maximizes air movement while minimizing noise. Its housing is made from heat‑resistant plastic, reinforced with metal inserts at critical stress points. The motor assembly uses a brushless design for longevity and low maintenance.

Blade Geometry

Each blade incorporates a subtle curvature that directs airflow efficiently through the radiator core. This geometry reduces turbulence and ensures uniform cooling across all coolant passages.

Housing & Mounting

The fan housing is molded to fit standard radiator openings, with mounting brackets that align precisely with OEM bolt patterns. The design allows for quick removal during routine service without the need for specialized tools.

Performance Characteristics

Engineered to deliver a high static pressure, the NRF 47319 Fan can push significant airflow through dense radiator cores. Its performance curve is optimized for low RPM operation, reducing power draw while maintaining effective cooling.

Airflow & Pressure

• Maximum airflow: 350 CFM (cubic feet per minute)
• Static pressure: 0.45 PSI
• Operating speed range: 1200–2400 RPM

Noise Levels

The fan operates at a whisper‑quiet level, with noise output measured at 48 dB(A) under typical operating conditions. This low acoustic signature is achieved through balanced motor design and vibration damping.

Compatibility & Applications

This radiator fan is specifically tailored for the Peugeot 307 series, including the 3/5‑door hatchback, Break, and SW models. It fits seamlessly into the OEM cooling system without requiring modifications.

Vehicle Models

• Peugeot 307 (all body styles)
• Peugeot 307 3/5 doors
• Peugeot 307 Break
• Peugeot 307 SW

Engine Types

The fan is compatible with both petrol and diesel engines equipped with a conventional water‑cooling system.

Installation Guide

Installing the NRF 47319 Fan involves removing the existing fan, aligning the new unit with the radiator mounting points, and securing it with the supplied bolts. The following steps provide a concise overview:

1. Disconnect Power: Ensure the vehicle’s battery is disconnected to prevent accidental activation.
2. Remove Old Fan: Unbolt the existing fan from the radiator housing and detach any electrical connectors.
3. Position New Fan: Align the NRF 47319 Fan with the mounting holes on the radiator. Verify that the blade orientation matches OEM specifications.
4. Screw in Place: Tighten the mounting bolts to the manufacturer’s torque specification (typically 10 Nm).
5. Reconnect Wiring: Attach the fan’s electrical connector, ensuring a secure fit.
6. Test Operation: Reconnect the battery and start the engine. Observe the fan for proper rotation and listen for any abnormal noises.

Maintenance & Longevity

The NRF 47319 Fan is designed for minimal upkeep. However, periodic checks can extend its service life:

• Visual Inspection: Check for blade damage or debris accumulation every 12 months.
• Electrical Test: Verify voltage and current draw during operation to detect potential motor issues.
• Lubrication: The brushless motor does not require lubrication, but ensure the fan housing remains free of dust.

Technical Specifications

Conclusion

The NRF 47319 Fan exemplifies engineering excellence in automotive cooling solutions. Its robust construction, efficient airflow design, and compatibility with the Peugeot 307 lineup make it an ideal choice for maintaining optimal engine temperatures. By integrating this fan into your vehicle’s cooling system, you ensure reliable performance, reduced thermal stress, and extended engine longevity.
