Des-Case Hydroguard Hybrid Breathers

Des-Case Hydroguard® breathers uniquely feature an expansion chamber and internal check valves that create a nearly-sealed system. Designed specifically for steady-state operations with minimal temperature fluctuations, these breathers provide excellent protection in continuous duty 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.
