Brand: Des-Case
Part Number:


From the expansion chamber system to the check valves, every element of Des-Case's patented HydroguardTM breather has been designed to stand up to a wide variety of industries and applications taking advantage of Des-Case's contamination control expertise.

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

Integrated Nylon Standpipe allows for greater chemical compatibility and vibration resistance. Polycarbonate Body Shock-absorbing, clear casing provides reliable service and easy maintenance. Threaded Mounting easily and securely replaces standard filler/breather cap with one of two adapters. Foam Pad disperses air evenly over filter media and silica gel. Patented Polyester Filter captures particles as small as 0.5 micron (73.5% efficiency), 3-micron absolute (beta-3 >200). Silica Gel/Desiccant removes water from incoming air, extending fluid and system life. Expansion Chamber
