Economic efciency of lters
Surface and depth lters series C, G, F, S, N and
R(x)
In the course of time, particles accumulate in the ltration
medium and reduce the space available for ow. Conse-
quently, the ow resistance will gradually increase, which
is indicated on the differential pressure gauge.
It is recommended to replace the lter elements at a
differential pressure of 0.4 bar or at least once a year,
whichever comes rst. If the element replacement is
delayed any longer, the economic efciency will suffer
since the higher differential pressure has to be com-
pensated by the upstream compressor. This will push
up the electricity consumption and lead to greater wear
on the compressor.
Activated carbon lter, series A
In order to prolong the service life of the elements, the
residual moisture of the inowing gas should not exceed
80 %. The capacity of the elements will be exhausted
after 6 months at the latest so that the element should
then be replaced.
The nominal diameters of the pipes should be as uni-
form as possible in order to avoid creating additional
ow resistance. Reduced pipe sections should only be
installed where required for the partialow outlets (ring,
connecting or supply lines).
Installation
CLEARPOINT water separators and lters undergo strin-
gent quality control procedures in the manufacturing plant
and are handed over to the forwarding agent in a perfect
condition. Upon arrival of the goods, please check for
any visible damage and, where appropriate, insist on a
corresponding note on the delivery receipt. Get in touch
immediately with the forwarding agent and arrange for
an assessment of the damage. The manufacturer is not
responsible for any damage caused during transport.
Positioning:
The plant operator must ensure that the device is
rmly xed and protected against exterior mechanical
effects.
The housing should be mounted in a vertical position.
Observe the direction of ow which is indicated by an
arrow on the housing.
Where required, the lter(s) should be additionally xed
using wall brackets (max. of 3 lter combinations with 3
lters per set of wall brackets). Incoming and outgoing
pipes (also at the condensate outlet) must be mounted
without placing them under mechanical strain. The wa-
ter separator/lter should be installed in an easily ac-
cessible position, so that any possible measuring points
will also be easy to see and access.
For replacing the lter elements it is necessary to leave
a handling space under the housing (see page 18).
Installation:
The housing bottom has a ne thread on the side facing
the lter head. For correct installation, the closed slide
should face to the front.
For better lter efciency, it is recommended to install
the device at a preferably cool, but frost-protected point
along the pipe network.
In the case of CLEARPOINT 12 PN 63 models supplied
with a BEKOMAT condensate drain as a standard, please
observe the instructions in the corresponding documen-
tation. For montering the BEKOMAT unit please use the
connection kit (see drawing on page 18).
The condensate must be disposed of in compliance with
the valid legal regulations. Condensate treatment using
an ÖWAMAT oil-water separator or a
BEKOSPLIT emulsion splitting plant represents a par-
ticularly economic solution.
Function
Water separator
The separator housings are equipped with internal
swirl inserts, that cause air entering at high speed to be
invested with a rapid rotating motion. The acceleration
this causes produces a large centrifugal force on the
particles and droplets within the compressed air, which
propels them onto the outer wall. Gravity causes them
to drip from there into the collecting chamber from which
they are then drained.
Filter C, G, F, S, N and R(x)
Solid particles are separated by impact and inertia ef-
fect, oil and water aerosols by coalescence effect. Due
to gravity, ltered out liquid particles gather in the lower
part of the lter housing from where they are discharged
either manually or automatically. With coalescence lters
the direction of ow through the lter element is from the
inside to the outside; with dust lters the ow moves from
outside to the inside.
Activated carbon lter A
The ow through the activated carbon bed proceeds
from the inside to the outside. Oil vapours and odours
are adsorbed on the activated carbon. The carbon is
incorporated into a binding fabric which ensures the
reliable retention of dust particles.
