Hydroguard hybrid breather can stand up to a wide variety of industries and applications. The breather is outfitted with an expansion chamber to isolate lubricants from all levels of ambient humidity. A clear, rugged polycarbonate casing allows for viewing desiccant as it changes color, indicating that the breather should be replaced. Check valves ensure no excess pressure/vacuum builds. Des-Case hybrid breathers attack the source of contamination, allowing your equipment and lubricants to run longer and harder. As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate and the color-indicating silica gel extracts moisture. The diaphragm allows for expansion and contraction of the air in the casing as a result of temperature variations during steady-state operations. 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.
