Function
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, filtered out liquid particles gather in the lower
part of the filter housing from where they are discharged
either manually or automatically. With coalescence filters
the direction of flow through the filter element is from the
inside to the outside; with dust filters the flow moves from
outside to the inside.
Activated carbon filter A
The flow 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.
Economic efficiency of filters
Surface and depth filters series
C, G, F, S, N and R(x)
In the course of time, particles accumulate in the filtra-
tion medium and reduce the space available for flow.
Consequently, the flow resistance will gradually increase.
It is recommended to replace the filter elements at a
differential pressure of 0.4 bar or at least once a year,
whichever comes first. If the element replacement is
delayed any longer, the economic efficiency 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 filter, series A
In order to prolong the service life of the elements, the
residual moisture of the inflowing 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
flow resistance. Reduced pipe sections should only be
installed where required for the partial-flow outlets (ring,
connecting or supply lines).

Installation
CLEARPOINT filters undergo stringent 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 housing should be mounted in a vertical position.
Observe the direction of flow which is indicated by an
arrow on the housing.
If the pipe network is affected by vibration, it is recom-
mended to install vibration dampers.
For replacing the filter elements it is necessary to leave
a handling space under the housing, see page 18, 20, 22.
Installation:
The lower part of the housing has a special fine thread
with a high carrying capacity. Subsequent to correct
installation, it must be checked whether or not the self-
locking bolt is firmly tightened and the filter thus secured
against opening during operation.
For better filter efficiency, it is recommended to install
the device at a preferably cool, but frost-protected point
along the pipe network.
The separation rates and service lives require filtration
using a prefilter which is one grade coarser at each level
(exception: coarse filters C series).
The tubing in front of the filter must be clean.
Optionally, the filters may be supplied with a needle valve
as a condensate outlet. The latter valve is equipped with
an additional diaphragm at the outlet side which prevents
a sudden pressure drop when discharging condensate
such that the operating personnel and devices are pro-
tected.
The condensate must be disposed of in compliance with
the valid legal regulations. Condensate treatment using
an ÖWAMAT oil-water separator or a BEKOSPLIT emul-
sion splitting plant represents a particularly economic
solution.
