The pressure gauge
of the pressure regulator with a specially-shaped seal.

Before initial operation check, the setting knob
unlocked and the compression spring is fully relaxed by
turning to the left. With pressure pre-sent on the primary
side, the setting knob is now turned to the right until the
pressure gauge indicates the desired secondary pressure.
Subsequent locking
pressure setting constant.
2 Filter with water trap
Draining the condensate
Manuel:
The collected condensate should be drained regularly and
promptly by turning the manual drain screw
Fully automatic:
The fully automatic drain valve is open when exhausted.
The valve closes when a pressure of > 2 bar is present
and there is an air flow of > 160 l/min. If the condensate
level rises so far that the float
briefly opened and the collected condensate is drained to
a certain level. Manual draining of condensate is possible
by turning the knurled screw
condensate can be caught by means of a sleeve LW 4.
Cleaning the sintered bronze filter
cartridge
After removing the reservoir, the filter cartridge
removed by unscrewing the baffle plate

The drops can be seen falling in the sight glass
Guide value für oil metering:
At 1,000 l/min air flow approx. 1–2 drops/min should fall.
Cleaning the reservoir
At zero pressure, the flange
