FAQ of Industrial Cooling Fans
What makes a fan suitable for radiator cooling instead of general ventilation?
Radiator cooling requires high static pressure, not just high airflow (CFM). Dense fin arrays create significant resistance (backpressure). Standard fans experience dramatic airflow drop under pressure, while LINKWELL fans are engineered with steep PQ curves to maintain airflow even at 150-300 Pa backpressure. Look for fans that publish full static pressure vs. airflow charts.
AC, DC, or EC fan – which one is best for my radiator application?
| Fan Type | Best For | Key Advantage |
|---|---|---|
| AC Fans | Industrial generators, stationary equipment, cost-sensitive projects | Direct mains connection, rugged, simple, 50,000h+ life |
| DC Fans | Mobile equipment, EVs, off-highway vehicles, battery-powered systems | Low voltage safety (12V/24V/48V), PWM speed control, IP68 available |
| EC Fans | Data center liquid cooling auxiliary radiators, premium energy-efficient systems | Up to 75% energy saving, PMBus communication, ultra-quiet |
What IP rating do I need for outdoor or dusty environments?
IP54: Protection against dust ingress and splashing water – suitable for sheltered outdoor installations.
IP55-IP56: Heavy dust resistance and powerful water jets – ideal for construction equipment, mining.
IP68: Continuous immersion protection (up to 1.5m for 30+ minutes) – required for off-highway vehicles, marine applications, or fans mounted low on mobile radiators.
How do I determine the correct fan size for my radiator?
Measure the available mounting footprint and core thickness. Common radiator fan sizes include:
Small radiators (ATV, motorcycle, small gensets): 92mm, 120mm fans
Medium radiators (automotive, compact equipment): 220mm, 250mm, 280mm fans
Large radiators (heavy trucks, industrial gensets, harvesters): 400mm, 500mm, 560mm fans or multiple fan arrays
Can you customize connectors, wiring length, and mounting brackets?
Yes – 100%. LINKWELL specializes in OEM/ODM customization:
Connectors: JST, Molex, Deutsch, TE, waterproof IP68 connectors, or bare wires
Cable length: Custom from 150mm to 2000mm
Mounting: Custom flanges, brackets, or rubber isolation mounts
