Relief valve
Ambient air is drawn in via the intake filter
1
on the
control valve
2
, condensed in the compressor unit
3
and cooled in the cooling coil
4
.
The condensed air is cleaned in the prefilter
5
.
Condensate is collected and drained in the
condensate trap
6
.
The subsequent diaphragm drier
7
dries the air to a
dew point at least 5 °C (41 °F) below the ambient
temperature.
The dehumidified air flows via the restrictor nozzle
8
and non-return valve
9
to the pressure vessel
10
.
Removal occurs via the coupling
11
.
The control valve
2
is pressurized with the vessel
pressure and controls the pressure generation
depending on the volume withdrawn.
Compressor with standby mode (optional)
For a compressor with standby mode, the ventilator
draws air from the central gas supply system via the
coupling
12
, non-return valve
14
and self-closing
coupling
11
. The compressor unit
3
is in standby.
When the pressure in the central gas supply
system falls below 2.7
±0.2
bar (40
±3
psi), the
pressure switch
13
switches the compressor unit
3
on.
When the pressure in the central gas supply
system rises above 3.2
±0.2
bar (46
±3
psi), the
pressure switch
13
switches the compressor unit
3
off again.
The relief valve
15
protects the unit against
excessively high pressure from the central gas
supply system.
