Simple, dependable lubricant protection

Brand: Des-Case
Part Number:


From the core standpipe to the tough polycarbonate exterior, every element of Des-Case's disposable standard breather has been designed to stand up to the wide variety of industries and applications taking advantage of Des-Case's contamination control expertise.

Des-Case breathers attack the cause of contamination, allowing your equipment and lubricants to run longer and harder.

How the Product Works
As wet, dirty air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate and the colorindicating 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 breather is outfitted with a resilient nylon standpipe and a clear polycarbonate body which allows for easy monitoring of the high-contrast silica gel.
