Every element of Des-Case’s Extreme Duty Disposable Breathers has been designed to take contamination control to a whole new level, standing up to a wide variety of applications in challenging environments.  The breather is outfitted with a rugged housing and an integrated standpipe, allowing for decreased oil misting while offering improved vibration resistance. Visual indicator windows show the desiccant as it changes colour, indicating that the breather should be replaced. Check valves keep out ambient humidity while the system is at rest.

Product Description

How it works

As wet, contaminated air is drawn through the unit, multiple 0.3 micron filter elements remove solid particulate and the colour-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.  The hydrophilic agent is partially reactivated by the dry air passing back through.
