RoHS compliance: No harmful substances are used in our products and their packaging in accordance with Directive 2011/65/EU.

REACH conformity: No substances of very high concern are used in proportions above 0.1%, which the European Chemicals Agency ECHA has published in the REACH Regulation in accordance with the criteria of Article 57 of Regulation (EC) No. 1907/2006.

Use and loading of an adsorber

During the use of an adsorber, the ambient air drawn in is dried by the desiccant silica gel. In addition, the dirt particles are separated from the air by means of the 3μm filter and remain in the adsorber.

The adsorbed water from the air is bound to the surface of the silica gel pores and does not change the structure of the silica gel
(SiO2). A color change takes place due to a pH value change. This process does not change the structure of the silica gel.

During the venting of the system, fine oil particles can flow into the adsorber, which are adsorbed by the activated carbon.
Basically, the activated carbon layer in the adsorber will absorb the oil mist (“if present”). If more oil flows out of the system, the silica gel will be contaminated. This oil can no longer be separated from the silica gel.
