VentGuard™
Desiccant Breathers

Check-valve technology that isolates the system and only breathes when necessary. The ideal solution for low-flow applications with intermittent operations where standard desiccant breathers saturate prematurely.

VentGuard™ Desiccant Breather

Product Overview

VentGuard™ breathers add check-valve technology to standard desiccant protection. Instead of constantly exchanging air with the environment, the system stays isolated and only breathes when pressure changes demand it. The result: silica gel desiccant doesn't saturate from idle exposure to humid air, and breather service life extends well beyond what a standard desiccant breather can deliver in the same conditions.

Check valves isolate the system and only allow breathing on pressure demand
Prevents premature desiccant saturation in humid environments
3 µm absolute particulate filtration
Color-change indicator: blue when dry, pink when saturated
Five sizes covering low to medium flow applications
Compatible with mineral oils, most synthetic oils, and diesel
