Instruction Manual Oil-Less Compressors
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.
