Xclude™ High Humidity Check Valve Breather
Ideal solution to protect against moisture and particulate contamination in low-flow applications with intermittent operations

This breather unit replaces the standard dust cap or OEM breather cap on equipment. As air is drawn into equipment through the breather, the layered filter elements remove particulates while the desiccant beads strip harmful moisture. While in service or during shutdown, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.

Check-valves ensure no excess pressure or vacuum builds. The internal check valves isolate the system until equipment needs to breathe.
