Activated Carbon Absorber

Prefiltered, clean air and dried compressed air (required inlet conditions) is led via the inlet (1) into the vessel and is lead through the gas diffuser to the adsorption vessel inlet (2) and through the activated carbon bed (3) from top to bottom. In the activated carbon bed, the compressed air is cleaned from oil vapours and hydrocarbons.
The cleaned air is lead via the lower gas diffuser (4) and the oulet of the adsorption vessel (5) to the compressed air network and to the point of use. By means of an oil indicator (6) at the outlet of the adsorber , the saturation of the carbon can be measured online, at any time.

Advantages:

Largely dimensioned amount of activated carbon:
High retention rates and long lifetime of activated carbon (residual oil content of < 0,003 mg/m3 and a lifetime of >10000 operating hours
Largely sized vessel diameters
Low flow speed, therefore no risk of abrasion of activated carbon and low differential pressure
Activated carbon adsorber with residual oil indicator standard
High operating safety, since residual oil content can be measured on-line at any time without having to de-install the adsorption vessel

Operating pressure:
AKC 0005 to 1000 min. 4 bar (g), max. 16 bar (g)
AKC 1350 to 8750 min. 4 bar (g), max. 10 bar (g)
