Guardian Desiccant Breather

Guardian Desiccant Breather

The Guardian has a modular platform that allows industry to configure the necessary breather for nearly any application and life expectancy. This makes better use of inventory dollars and ensures that every maintenance dollar is used wisely.

It is manufactured from Tritan® that provides impact, temperature and chemical resistance and is also BPA free. Incoming air is directed through the filters and desiccant, but all exhaust air is expelled directly out to atmosphere, thus elongating the life of the desiccant and breather.

The top check valves are on the inlet and the bottom check valves are on the outlet. When the breather is in static conditions (no air movement) the check valves prevent ambient air from coming into contact with the desiccant, thus extending breather life.

Because of the modular design feature, the Guardian has an optional Stack Ring, which allows multiple cartridges to be stacked atop each other for longer breather life and higher moisture removal capabilities. It also means less servicing and maintenance costs. The replaceable cartridge can be a combination of desiccant, HEPA grade .3 micron filter, molecular sieve for low humidity conditions, and activated carbon for fume and odor removal depending on what the application requires.
