What to Consider When Seeking a Quality Contamination Control Breather

Air Sentry breatherContamination control breathers (or desiccant breathers) continue to be at the top of the list of essentials for preventative maintenance and attacking contamination. They are low cost option that proves a significant return on investment. Today, there are many variations to choose from; here are a consider when choosing a quality breather.

Headspace
It’s important to understand how much the headspace of a system can fluctuate. For example, the headspace in a splash-lubricated gearbox will fluctuate less than that of a hydraulic system reservoir, where there are large volumetric changes within the sump. This volumetric flow rate must be within the capabilities of the breather, or it may cause a pressurization condition inside the component.

Environment
If you’re working in severe environments (such as those with large amounts of dirt), choose a breather than can withstand the expected amounts of contamination. Consider a breather with a check valve or bladder assembly to help prolong its lifespan. Our Air Sentry Breathers in North Carolina feature an isolation check valve, which isolates the absorbent from exhaust air.

Construction
Tritan® is a material highly resistant to impact and chemicals with a broad range of operating temperatures. This means a longer life for your breather and your equipment.
