Air Sentry® set the standard for contamination control breather technology in 1997, creating new state-of-the-art features that reduced particulate and moisture contamination. This innovative breather line was the first to integrate check valve technology and the first to offer replacement desiccant/filter cartridges, significantly reducing maintenance costs.

The clear view 360 degree design makes it east 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 absorption of moisture and confirm the breather is getting the job done. 

Air Sentry products cover a wide range of application requirements. The line consists of Good, Better, and Best options designed to meet your specific application and duration specifications.
