Adsorber components and their tasks.

Thread (A): Connects system and adsorber. Typical transformer connections (DIN42562, DIN42567A, DIN42567B, DIN42567C-G1"f, ...) are available.

Activated carbon disk (B): Adsorbs oil particles and aerosols from exhaust air. The activated carbon layer not only protects the desiccant from contact with oil, but also prevents harmful oil mist from escaping the system.

2µm fleece filter (C): Filters finest dust and dirt particles from supply air and thus protects the system from getting filthy. 

Plastic housing (D): Protects the inner workings of the adsorber. The refillable plastic housing is durable and UV-resistant. 

GIEBEL Xdry® (E): Ensures effective drying of the air flowing through and indicates by changing color from orange to green when it is time to replace the adsorber.

Foam filter disk (F): Filters coarse dust and dirt particles from the supply air.

Valve (G): Enables air exchange with the environment when the system draws in or pushes out air for pressure equalization and at the same time protects the desiccant from unnecessary loading while the system is at a standstill.

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 (E) then separates moisture up to 2% RH (average 10% RH). A 2μm filter (B) 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 that are separated by the activated carbon (F). 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.
