General description of the CLEARPOINT® V activated-carbon adsorber
16 CLEARPOINT® L 205 – L295 V
8 General description of the CLEARPOINT®V activated-carbon adsorber
The CLEARPOIINT®L 205-295 V activated-carbon adsorbers serve exclusively to separate residual oil
contents in the form of vapour or aerosol from compressed air and nitrogen.
The compressed air should be predried, and should not exceed a moisture content of 30% and a
temperature of +35°C. Exceeding these values will reduce the service life of the activated-carbon
adsorber. Therefore, the employment of a refrigeration or even an adsorption dryer is required upstream
of the activated-carbon adsorber.
With an appropriate dimensioning and when the operating parameters and load limits of the incoming
compressed air on which the dimensioning is based are adhered to, the oil content is drastically reduced
through the activated carbon contained in the adsorber. Besides the temperature, operating pressure and
volume flow, the exact life expectancy and dimensioning depends on the applied type of oil, the
compressor type and the humidity of the compressed air.
The following modifications of the operating conditions may lead to a reduction in the activated-carbon
adsorber’s service life:
Increase of the volume flow
Increase of the operating pressure
Increase of the relative humidity of the compressed air
Increase of the residual oil aerosol content at the inlet.
Therefore, you should benefit from the expertise of our special departments to design your activated-
carbon adsorber.
Depending on the actual quality of the compressed air in your supply network, a prefilter and at least a
refrigeration dryer is required for the incoming compressed air. The prefilter ensures that the oil aerosol
content of the incoming compressed air does not exceed a value of 0.01 mg/m3. By treating the
compressed air with a refrigeration dryer, the maximum permissible humidity of the compressed air of
30% at the inlet into the adsorption dryer is guaranteed.
Not included in the scope of delivery:
Prefilter
Refrigeration dryer / adsorption dryer
Afterfilter
Internal tubing
Oil check indicator

Operating principle
CLEARPOINT® L 205 – L295 V 17
9 Operating principle
The CLEARPOINT®V activated-carbon adsorber from BEKO TECHNOLOGIES GMBH functions
according to the principle of the accumulation of oil molecules on the surface and in the porous structures
of special activated carbon.
The activated carbon is in a container, through which the medium flows continuously top down.
The compressed air, from which the oil fractions need to be removed, enters the device through the
upper connection at the container.
Prior to that, the compressed air must have been filtered at least through a prefilter (residual oil aerosol
content 0.01 mg/m³ at +20°C) and should not exceed a relative humidity of 30% and a temperature of
+35°C. The service life of the activated-carbon adsorber will be reduced when these values are
exceeded. Therefore, the employment of a refrigeration dryer or even an adsorption dryer upstream of
the activated-carbon adsorber is required.
The compressed air flows through a compressed-air distributor and travels top down through the volume
filled with activated carbon. During this process, the activated carbon adsorbs the majority of the oil
aerosols and the oil vapour. Subsequently, the compressed air purified in this manner flows to the outlet
through the lower compressed-air distributor.
This process takes place without regeneration phases. The activated carbon is thus gradually saturated
with oil molecules and therefore needs to be replaced when the predefined service life has expired.
Activated carbon is able to reliably adsorb a wide range of non-polar hydrocarbons; there are, however,
restrictions regarding the adsorption capacity as far as polar hydrocarbons are concerned (e.g. benzene).
It must also be taken into account that abruptly changing operating conditions (pressure, volume flow)
may lead to desorption of the already intercalated hydrocarbons.
It is explicitly recommended to provide a shut-off valve both upstream and downstream of the activated-
carbon adsorber and to install a bypass around the activated-carbon adsorber. These components are
not included in the scope of delivery.

10.2 Available options
Prefilter It is recommended to use a BEKO ultrafilter with an automatic
condensate drain. This prefilter ensures that the oil aerosol content of
the incoming air does not exceed a value of 0.01 mg/m³.
For details, please refer to the following filter selection table.
Afterfilter Downstream of each activated-carbon adsorber, an afterfilter
(minimum requirement 1 µm) must be installed that retains dusts and
particles from the activated carbon that develop due to the way the
system operates.
It is recommended to use a BEKO dust filter in an oil and grease-
free version.
For details, please refer to the following filter selection table.
Compressed-air dryer For the safe functioning of the CLEARPOINT®V, the compressed air
must not exceed a relative humidity of 30% at the inlet into the
activated-carbon adsorber. The service life of the activated-carbon
adsorber will be reduced when these values are exceeded. Therefore,
the employment of a refrigeration or even an adsorption dryer is
required upstream of the activated-carbon adsorber.
Please contact our specialist departments to select a suitable
compressed-air dryer.
Oil check indicator For the rough assessment of the compressed-air quality, an oil check
indicator can be used. The oil check indicator can be installed on the
head of the CLEARPOINT dust filter (you will find the adapter and oil
check indicator, as well as replacement test tubes, in our price list).
METPOINT®OCV residual
oil measuring device For the continuous qualitative assessment of the compressed-air
quality, the use of our METPOINT®OCV residual oil measuring device
is advisable. By means of a measuring section, the METPOINT®OCV
can be installed in the pipework downstream of the afterfilter, and will
then show the residual oil vapour content ONLINE.
