Pressure regulator and moisture separator for compressor
The gauge indicates the operating pressure of the airbrush.
To adjust the pressure, pull the knob upwards, then it can be turned. Turn clockwise to increase pressure; turn counterclockwise to decrease pressure.
Water can be removed from the moisture separator by pressing the button on the bottom (first remove pressure from the compressor).
The pressure gauge goes up to max. 7 bar.

When mounting it is recommended to use Teflon tape to seal the couplings.
