Function
() Moist compressed air enters
through the head (A) and flows
downwards through the core tube of
the membrane element (D).
() The outlet of the core tube is
connected to a nano filter (C) which
separates the compressed air from
aerosoles and particulate matter.
Separated condensate fluid is dis-
charged from the bottom.
In the area of the Nanofilter element,
the direction of flow is reversed and
the moist compressed 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 at-
mospherically expanded through a
nozzle (E).
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.
(4) This extremely dry purge air is
channelled through the membrane
element (D) along the outside of
the membranes. Due to the ordered
structure of the membranes, the
purge air is very evenly distributed.
(5) 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 com-
pressed air into the purge air.
(6) Dry compressed air flows out of
the DRYPOINT M PLUS membrane
dryer.
(7) Moist purge air is discharged into
the environment.
