Air Sentry® set the industry gold standard with their first line of contamination control breathers in 1997, and now that standard is raised with GUARDIAN®.

Watch the video below to see how the Air Sentry® GUARDIAN® protects your process fluids from particulates and moisture.

Air Sentry® breathers should be an integral part of any proactive maintenance and reliability program. The breathers are designed to replace the breather cap or air filter on gear boxes, hydraulic fluid reservoirs, bulk storage tanks, oil drums, oil-filled transformers, and other fluid reservoirs.  Most older style air venting methods provide minimal, if any, contamination control.  Air Sentry® breathers provide the first line of defense in contamination control methodology, utilizing patented designs and featuring color indication silica gel and self-cleaning 2-micron filtration.

Why is Contamination Control Important?

There are two important threats to productivity that an Air Sentry breather can protect you from:

Particulates
One research group found that greater than 75% of all machine wear related failures were due to particulate contaminants. Frequently the greatest cost of equipment failure is not the component replacement cost, but the labor production downtime. Most particles start off as dirt that becomes airborne, finds its way into lubricant and fuel reservoirs, and is later transported to bearings, bushings, seals, valves, and other machine components. There they become key ingredients in abrasion, erosion, and fatigue failures. The contaminants also cause lubricant degradation, shortening the life of the lubricant and decreasing its ability to lubricate.
