Function
(1) Moist compressed air enters through
the head (A) and flows downwards
through the core tube of the membrane
element (D).
(2) The outlet of the core tube is connect-
ed to a nano filter (C) which separates
the compressed air from aerosoles and
particulate matter. Separated condensate
fluid is discharged 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 element
a partial flow of compressed air is con-
tinuously diverted and atmospherically
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 chan-
nelled 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 humid-
ity difference, moisture diffuses from the
compressed 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.
