Function
() Moist compressed air enters

through the head (A) and flows
downwards through the core tube of
the membrane element (D).
In the bottom area, the direction of
flow is reversed and the moist com-
pressed air then flows through the
membranes of the inner membrane
element (D).
3
() At the end of the membrane ele-
ment a partial flow of compressed
air is continuously diverted and
atmospherically expanded through
a nozzle (E).
4
Due to the expansion, the diverted air
– referred to as purge air – becomes
much drier because the moisture
contained in the compressed air is
now distributed over a much greater
volume.
(3) This extremely dry purge air is
channelled through the membrane
6
element (D) along the outside of
the membranes. Due to the ordered
structure of the membranes, the
purge air is very evenly distributed.
(4) Consequently, two flows of air
with different humidity levels move
in a countercurrent direction through
the membrane element, separated
only by the membrane wall:
inside the moist compressed air,
outside the dry purge air. As a result
of the humidity difference, moisture
diffuses from the compressed air into
the purge air.
(5) Dry compressed air flows out of
the DRYPOINT M membrane dryer.
(6) Moist purge air is discharged into
the environment.
