• Motor Type: Brushless DC motor – offers low maintenance, high efficiency, and extended service life.
• Voltage Range: 12 V / 24 V – compatible with both automotive electrical systems and industrial power supplies.
• Speed Control: Variable speed drive (VSD) capability – allows precise adjustment of fan RPM to match cooling demands, reducing noise and energy consumption.
• Construction Material: Stainless steel housing with corrosion‑resistant coatings – ensures durability in harsh environments such as high humidity or salt exposure.
• Blade Design: Optimized aerodynamic profile – maximizes airflow while minimizing turbulence, resulting in efficient heat transfer.

Performance Specifications

Compatibility and Applications

The VEMO V40‑01‑1043 is engineered to fit a broad spectrum of vehicles and equipment, including:

• Automotive engines – especially those from General Motors, Opel, Vauxhall, and other manufacturers requiring a 390 mm radiator fan.
• Industrial machinery – such as generators, compressors, and HVAC units where reliable cooling is critical.
• Marine propulsion systems – the corrosion‑resistant housing protects against saltwater exposure.

Installation Guidelines

1. Mounting: Secure the fan to the radiator or heat exchanger using the provided mounting brackets. Ensure that the fan is centered and aligned with the airflow path.
2. Electrical Connection: Connect the motor terminals to a suitable power source, observing correct polarity. If using a variable speed drive, integrate it between the power supply and the fan controller.
3. Cooling Fluid Flow: Verify that coolant passages are unobstructed and that the radiator is properly filled with antifreeze mixture.
4. Testing: After installation, run the engine at idle to confirm that the fan engages correctly and that airflow is adequate. Check for any abnormal vibrations or noises.

Maintenance Tips

• Inspect the fan blades every six months for dents or corrosion; replace if necessary.
• Clean the housing and surrounding area to prevent dust accumulation, which can impede airflow.
• Check electrical connections for tightness and signs of wear. Replace any frayed cables immediately.
• Lubricate the motor bearings according to the manufacturer’s schedule (typically every 12,000 km or 24 months).

Benefits of Choosing VEMO V40‑01‑1043

• Reliability: Brushless motor design eliminates brushes that wear out, reducing downtime.
• Energy Efficiency: Variable speed control allows the fan to operate only as fast as needed, cutting power consumption by up to 30 % compared with fixed‑speed fans.
• Quiet Operation: Aerodynamic blades and low‑noise motor result in a quieter engine bay or machinery compartment.
• Durability: Stainless steel construction resists corrosion, extending the fan’s service life even in harsh environments.
• Versatility: Wide voltage compatibility and standard size make it easy to retrofit into existing systems.
