9. PRODUCT FUNCTION
9.1. Compressor with adsorption
dryer
The compressor air pumps (1) draw in air
through the inlet filter (8) and compress it
through a non-return valve and into a
manifold, from which it is routed to the
adsorption dryer (3) through a connecting
hose. From the inlet to the dryer module, the
air is first cooled in the integrated cooler (17)
and then moves through the condensate
separator (29), entering the active chamber
with adsorbent (19), where the air is then
dried. A portion of the dry air is fed into the
second, regeneration chamber, where this air
is used to remove moisture from the
adsorbent, after which it is released with the
accumulated condensate through the silencer
(27). Chamber operation (desiccant
regeneration) is cyclically switched. Dry and
filtered air then passes through the non-return
valve into the air tank (2).

The range of the pressure
switch on the configured
assemblies may only be
adjusted after prior
consultation with the
manufacturer.
Adjusting the pressure setting
of the safety valve is expressly
prohibited.
The pressure relief valve automatically
begins to vent air from the system if the
pressure in the compressed air circuit
exceeds its pre-set value. The pressure relief
valve then closes as the pressure drops.
Pressure in the compressed air
circuit can only increase
because of an increase in flow
resistance in the compressed
air lines or as a result of a dryer
malfunction (e.g. solenoid valve
malfunction, an increase in flow
resistance through the drying
media, etc.), and therefore the
repeated opening of the relief
valve requires a dryer function
check and repairs if necessary.
Consultation with the
manufacturer is required before
any adjustment is made to the
relief valve!
The outlet openings on the
relief valve must not be blocked
and the flow of compressed air
through them may not be
restricted.
