*) These FS do not contain a filter bypass, which
will ensure a continuous flow of air when
replacing the filter element. Such a set must be
ordered separately
.
Filter set regulator assembly
The compressor may be equipped with a
pressure regulator of the compressed air
outlet if specified. The regulator must be
selected according to the application to the
filter set, or separately. The regulator shall
ensure constant pressure at the outlet.

Filter set brackets
A suitable bracket must be
ordered for every filter set.
Compressor module enclosure (noise
reducing)
Enclosing the compressor module reduces
the noise generated by the compressor by up
to 11 dB(a) compared to the compressor
module without the enclosure while ensuring
sufficient
cooling for the air pumps
themselves for S1 class continuous
operation.

9. PRODUCT FUNCTION
9.1. Compressor with adsorption
dryer
Fig. 1: Compressor air pumps (12) draw in
atmospheric air through the intake filters and
compress it through non-return valves into
the compressed air system. A connecting
hose (13) connects this system to the
external adsorption dryer (8). From the inlet
to the dryer module, the air is first cooled in
the integrated cooler (9) and then through the
condensate separator (10), entering the
active chamber with adsorbent (11), where
the air is dried. A portion of the air is fed into
the second, regeneration chamber, where
this air is used to remove moisture from the
adsorbent, after which it is released through
the silencer (21). The active chamber
switches on a cyclical basis. Dry and filtered
air then passes through the non-return valve
(23) into the air tank (2). The treated
compressed air is ready for additional use in
the air tank.
