Type DSS 120-630 activated carbon adsorber with filling A (activated carbon) are mainly designed for separating oil vapours from compressed air flows (dry-type separation) in pressure levels up to 11 bar for compressed air without aggressive substances. Activated carbon adsorber are therefore used, if there are no liquid contaminants, especially water or oil, in the compressed air flow. Due to the properties of activated carbon some other gaseous contaminants are separated as well.

Type DSS 120-630 activated carbon adsorber vessels are made from high-quality welded steel parts. For surface finishing purposes and for increasing the resistance the vessels are sandblasted and primed (except for the sealing surfaces). Finally, an additional layer is painted on the outer side.

Compressed air, flowing from top to bottom, enters the vessel through the top inlet connection, passes the top flow distributor, then the activated carbon filling resting on a support screen. Within the activated carbon filling oil vapours and other organic substances (mainly long-chain hydrocarbons) are separated by an adsorption process. Finally, the treated and thus cleaned com-pressed air leaves the vessel at the bottom outlet connection.

The flow distributor, supplied as standard, distribute the com-pressed air flow to the entire surface of the activated carbon filling thus providing a evenly distributed flow. At the same time the activated carbon granulate is reliably kept inside the vessel.

An oil indicator equipped with pressure regulator and manual valve is provided as a standard as well. An optional 1 micron  downstream filter (fine filter) is recommended to hold back abra-sion of the activated carbon.

The activated carbon adsorber comply with the requirements of the Pressure Equipment Directive 97/23/EC, and have the CE marking of this European directive.
