Visco fans

 Sale of  BWCS, BEHR Visco fans

Fans with viscous couplings utilize friction in liquids, which is dependent on temperature
 

 Transmits torque with variable skidding

 Fan operates with the use of the viscous coupling only if it is really required
 Aerodynamic flow – impact cooling is sufficient in about 90% of driving situations
 It is fixed using a union nut with a left-hand thread on the water pump shaft
 During storage, it should not be inclined at more than 45° for a lengthy period of time – especially a coupling that has already been operated
