V activated-carbon adsorber

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/m
3
. 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.
