6. Operating description
6.1. Air circuit
The air supplied to the head passes through the head chamber and suction valve to the
cylinder. Once compressed in the cylinder, the air is forced through the pressure valve to
the end cooler.
After being cooled, the air passes through filters (option) and is supplied to the air tank.
As water condenses during the cooling and compressing process, the KOMPBERG
BKB22 TWIN booster cooler is provided with a valve for draining the condensate.
6.2. Lubrication system
Oil sucked by the gear pump is initially purified in the suction filter. Oil is forced through
the fine filter to the hole in the crankshaft, and further on through gaps in the crank pin to
the crank bearing bushings and pins.
