3. Remove the seal in the cover and replace it with the new one.
4. Remove the foam disk and empty the activated carbon.
5. Pull out the filter element.

7. Insert a new foam disc, fill in silica gel colourless and insert another foam disc.
8. Insert a new filter element and then fill in fresh activated carbon. When filling in the
activated carbon, lightly tap the housing with a soft object (e.g. the ball of your
hand) to compress the filling.
9. Insert the foam disk and then reclose the lid using the clips.
10. Screw the adsorber back onto the system.

Order of spare parts
For a constant operational readiness of the adsorber and thus of the plant, make sure that a spare parts
kit is always in stock.
The time until the complete colour change from colourless to brown and thus the service life of the
adsorber depends on various factors:
•Number and duration of flow and loading intervals.
•Quantity of oil particles and mists emitted.
Storage of adsorbers
All articles filled with activated carbon are packed airtight. To avoid damage to the activated carbon, it
must be stored in dark and dry rooms at -10°C to +30°C.
Section 8: Disposal
At the end of its useful life, the device must be disposed of in accordance with the relevant legal
regulations. Metal and plastic parts should be separated and disposed of separately.
The loaded activated carbon must be disposed of according to the absorbed substance (e.g. hydraulic or
gear oil).
Activated carbon and silica gel are not classified as hazardous substances under European Union
legislation (Regulation EC No 1272/2008). It is not subject to mandatory labelling according to EC
Directive (67/548/EEC or 1999/45/EC). Activated carbon and silica gel are not classified as substances
hazardous to health or the environment.

Section 9: Risk and hazard analysis
1. Oil flows out of the plant
Porous seals
Air containing oil can flow from the adsorber into the environment at the porous points. This means that
no protection against oil mist in the air is possible.
Saturated activated carbon
When the activated carbon is saturated, it can no longer absorb oil. As a result, oil particles from the
system are released into the air.
Air flow rate too high
If the air flow is too high, the contact time between oil particles and activated carbon is too short. This
allows oil to flow out of the system.
2. Positive or negative pressure builds up in the system
Air flow rate too high
Too high an air flow rate can cause over- or underpressure in the system.
Contaminated filter element
The filter unit can be clogged by dirt particles and can therefore build up pressure in the system.
Activated carbon saturated
Once the activated carbon is completely saturated, oil can deposit and clog the adsorber.
3. Adsorber is damaged
Material resistance
When selecting the adsorber, the ambient and operating conditions should be considered. An aggressive
environment or liquid in the container can damage the adsorber.
Temperature range
The ambient and operating temperatures should not exceed or fall below the specified range, otherwise
the adsorber may be damaged.
Improper handling
Incorrect or improper handling can damage the adsorber. The recommended installation must be
observed.

Strong vibrations
Strong vibrations of the plant can damage the adsorber.
Pressure range of the system
The adsorber should not be exposed to over- or underpressure above 0.5 bar, otherwise the housing
may be damaged.
Cleaning of the adsorber
For cleaning the adsorber, the use of a mild soap in combination with water is recommended. The use of
brake cleaner will damage the adsorber and is no reason for complaint.
Thread of the adsorber and accessories is damaged
When mounting the adsorber on the system, the threads must be
slightly moistened with oil. If the threads are not oiled, this can
lead to the individual thread rubbing and is not a reason for
complaint.
Section 10: Maintenance plan
1. Check seals for wear
Check The O-rings installed in the adsorber and the flat gasket must be checked for perfect
condition. For this purpose, the seals in the cover, on the filter and on the connection
should be checked and examined for brittleness.
Cycle Half-yearly
Measures In case of existing damage, a new spare parts kit or a new adsorber should be used.
2. Visual inspection of the activated carbon
Check The loading condition of the activated carbon must be determined by visual inspection of
the adsorber. The colour white indicates that the activated carbon can still adsorb oil and
that air is cleaned. If the activated carbon is completely saturated, the colour changes
from white to brown.
Cycle Half-yearly
Measures If the activated carbon is loaded, a new spare parts kit or a new adsorber with fresh
activated carbon should be used.

3. Check filter unit for impurities
Check Remove the cover and remove the foam disk. Then empty the activated carbon. The filter
unit can then be removed. This should be checked for impurities and should be free of dirt
for smooth operation.
Cycle Half-yearly
Measures The filter element is part of the spare parts kit and should be replaced if it is contaminated.
4. Visual inspection of the adsorber
Check The adsorber, including the connection, must be visually checked for damage. Damage
can occur due to various environmental or operating conditions.
Cycle Annually
Measures If the adsorber is damaged, it must be completely replaced to ensure full functionality.
5. Replacing the wearing parts
Check The wearing parts, in particular the seals, the activated carbon and the filter element, must
be checked with regard to their condition.
Cycle Every two years
Measures Regardless of the result of the test, it is recommended to replace the wearing parts by
using a spare parts kit or a new adsorber to ensure smooth operation.
