At present the company research and production of silicone oil clutch drive series fan only WR241-300 cooling fan. The use of silicone oil clutch drive can be based on the engine temperature automatically adjust the cooling fan speed, the engine at the best working temperature to meet the cooling fan speed requirements.
The main performance parameters : the wind turbine impeller speed at 2750r / min, static pressure 1200Pa, the cooling air flow ⥠2.1kg / s; fan wheel speed 4850r / min, static pressure 1600Pa, the cooling air flow ⥠2.5kg / s; When the input speed is 2750r / min, the impeller speed noise ⤠92dB; when the input speed is 4850r / min, the noise ⤠98dB. Main features: with compact structure, compact size, light weight, easy installation and so on, and has a low speed, air volume, low noise, vibration, low energy consumption, high efficiency, safe and reliable, stable, long life Exnt performance.
