Contamination 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.
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.
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.
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.
