4.2 Function description
From the filled adsorbent material, (active carbon in this case), oil vapours and odorous and
aromatic substances are stored in the open pores of the active carbon, thus reducing its con-
tent in the compressed air.
Through the joining pipe and possible pre-treatment, the compressed air is fed via the inlet
into the diffuser (flow distributor and sieve). The compressed air is hereby distributed over the
whole vessel cross-section for optimum efficiency. Based on the laws of physics and a prede-
termined contact time, the abovementioned contaminations are stored in the open pores of
the active carbon. The cleaned air then exits the vessel again through a sieve on the outlet.
As the temperatures rise, the performance of the active carbon is reduced since the hydrocar-
bon chains (oils) become shorter and shorter and cannot be absorbed as effectively.
The contaminations collected in the active carbon gradually saturate the material. It cannot be
regenerated in the process and must be replaced. With the appropriate compressed air quality
at the inlet, it is possible for the service life to exceed 10,000 hours.

Monitoring the operation
The following components are provided for regular monitoring:
The pressure gauge shows the operating pressure.
The oil check indicator is used to regularly measure
the residual oil. The needle valve is
only opened for the duration of the measurement. Based on
the discolouration, the indicator provides information about the saturation
of the active carbon.
