When air flows through a gearbox breather, it can introduce moisture into the system. Temperature fluctuations cause the water in the air to condense, which can cause corrosion on the drive gears and oxidize oil, possibly leading to serious damage of components.
With Stauff’s desiccant breathers, air first passes through a drying agent of non-toxic gel to remove moisture and then through a replaceable air filter element with a micron rating of 3μm to remove particulate matter. As moisture is absorbed, the drying agent gradually changes from red to orange. When it is orange, users should replace the drying agent.
