Xclude™ High Humidity Expansion Chamber Breather
Protection form moisture and particulate contamination in low-flow, steady-state operations

These high humidity desiccant breathers feature an expansion chamber to isolate lubricants from all levels of ambient humidity, keeping out harmful particles and creating a nearly sealed system to protect the equipment. The diaphragm allows for expansion/contraction of the air within the casing as a result of temperature variations during steady-state operations.

As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulates while the color-indicating silica gel extracts moisture. When air is expelled from the container, the top foam pad prevents oil mist from contacting silica gel or entering the atmosphere.
