Replace DC EX-4 Desiccant Breather
Desiccant Breathers Protect Diesel Fuel Storage Reservoirs, Gearboxes, Pumps And Other Industrial Equipment From Moisture And Particulate
Check Valve Design — Extended Service Life
Cross Replace DC-VG-4 features a built-in check valve that provides a system pressure increase without generating excessive strain, and only operates when necessary. This mechanism prevents premature saturation of silica gel and significantly prolongs product service life.
When contaminated air enters the top of the breather, it passes through layered filter media, preventing solid particles from entering the system and causing undue wear to equipment surfaces.

Application
For example, a gearbox for wind power generation:
Gearboxes in wind turbines differ from those in high-speed machinery. In industrial gearboxes, the progress of failure can occur in weeks, days, or even hours. In wind turbines, the impact of contaminants on slower turning gear drives is slow and insidious. Nevertheless, the mean time between failure (MTBF) for gears and shaft-support bearings can be increased by as much as two to three times by maintaining optimum levels of fluid cleanliness and dryness.
