Cleanfix radiator fans use a thermo-mechanical servo on each blade to keep the pitch at the proper angle to conserve fuel when a diesel engine's temperature requires less than maximum pitch, but will engage the fan fully when temperatures rise.
In addition, the company's design includes a pneumatically-operated reversing system to give the fan a maximum "blowing" capacity when it is reversed to clean radiators and air intake screens. The reversing feature can be accessed by a pre-set timer, or by manually switching to the "reverse" mode.
Research on the fan in Germany shows more than 6% fuel savings through more precise engine temperature control and free-flowing air-intake systems.
Cleanfix comes as a standard or as a factory option on many major OEM diesels, but the fan can be easily retrofitted to existing engines with an available mounting kit.
