Clean compressed air. The BOGE DCZ activated carbon adsorber cleans compressed air reliably and efficiently to a residual oil content of just 0.003 mg/m³. As the post-filter is already mounted, you can connect the adsorber directly. The surface of the activated carbon binds existing oil aerosols and vapours, as well as odours, together in the compressed air. The pre-dried compressed air flows through the high-grade activated carbon in the tanks from top to bottom.
