eliminate and protect against moisture and contaminants in gear units, lubricated reservoirs, and electrical transformers,

As air is expelled from the reservoir (A ), it flows back through the unit to the outside. A partial regeneration of the desiccant occurs as some of the water vapor is carried out with the air (regeneration reaches approximatly 80%). It is the same kind of work than on an adsorber air dryer.

Also, the knit of the patented polyester filter is designed to backflush most of the retained particules out of the unit (B). In fact it cleans itself at approximatly 95%. After six years (6) of uses on the European market, usually customers reach 12/14 months before changing DES-CASE breathers.
