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

As air enters the breather through the nipples at the bottom of the unit (A), it contacts a low-density foam filter (B). The air then passes through a knitted polyester filter element (C) that retains all particulate matter down to three micron absolute. This filtration level exceeds most industry standards and provides the protection necessary to ensure maximum component life and system performance.


Next, the air passes through a stack of desiccant crystals (D), which removes the water vapor. The desiccant is chemically inert, non-toxic, and non-corrosive.

Finally, the air go through a second polyester filter and foam filter (E) to ensure that no particle from the desiccant stack will enter the reservoir. The clean, dry air flows through the standpipe (F) into the tank or reservoir, assuring maximum protection of components and fluids.

As water vapor is absorbed in the breather the desiccant stack slowly changes color from blue to pale pink. The pink color indicates maximum saturation and the need to replace the unit [ see the color evolution]. . However, to prolong the desiccant's life, the drying agent actually backflushes itself when dry air leaves the tank through the breather, extending the period before replacement is needed.
