Components.
Hover over the components of the adsorber and find out what important tasks they perform to keep your systems dry and clean.
ADSORPTION PROCESS:
If the oil level in the system drops, air flows in to equalize pressure. This air enters the adsorber via the valves (G) and flows through a coarse filter (F), which separates larger dirt and dust particles. The GIEBEL Xdry® filling (D) then separates moisture up to 2% RH (average 10% RH). A 3μm filter (C) removes even the finest dirt and dust particles from the supply air.
Dry and clean air enters the system.
DESORPTION PROCESS:
If the oil level rises, air is pressed out of the system. This air contains oil particles and aerosols. Larger oil particles condense on the oil demister (E) and drip back into the system. Finer oil particles and aerosols are separated by the activated carbon (B). Some of the previously adsorbed moisture is removed from the desiccant as the air flows out, ensuring cyclical self-regeneration.
Clean air escapes the system.
