Replacing air dryer cartridge
Fig. 50: Air dryer cartridge
The air dryer serves to withdraw the moisture from the
compressed air. This is done by directing all the compressed
air through a cartridge filled with drying agent. The drying
agent has the capacity to absorb the moisture.
We recommend changing the air dryer cartridge at least
once a year.
