Desiccant Breathers

Whitmore®'s Desiccant Breather line, Air Sentry®, sets the standard for contamination control. These breathers have state-of-the-art features that reduce particulate and moisture contamination, keeping your equipment and fluids lasting longer. The innovative breather line integrates check valve technology in a desiccant breather and offers replacement cartridges, to significantly reduce maintenance costs. The clear view 360 degree design makes it easy to inspect the saturation of the color-changing silica gel from a distance. The inert silica gel turns from gold to dark green to visually indicate the adsorption of moisture and confirm the breather is getting the job done.
