6.      COOLING SYSTEM 
 
6.1. GENERAL 
 
 

Cooling of the oil-less compressor is twice as efficient because of their mode of operation: 

 
 

The compressor  is equipped with a flywheel which draws the cooling air through the flywheel cover from the 

 

surroundings and thus cools the cylinder, both intercoolers and the after-cooler.  The fan blades are mounted on 

 

the flywheel and are powered by the driving motor. 

 
 

Additional cooling of all mechanic parts such as crankcase, connecting rods and pistons is effected by drawing 

 

the air in, which has to be compressed for the first stages, via the crankcase. 

 
 

Refer to chapter 8 for proper installation and cooling air supply.
