AIR SENTRY

Air Sentry breathers first set the gold standard with their introduction in 1997. Achieving near total control of fluid system contamination, Air Sentry has led the industry by improving productivity, prolonging fluid life, reducing maintenance costs and controlling expensive downtime. The pace of a competitive world absolutely requires this level of performance.

Air Sentry 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. Air Sentry desiccant breathers adsorb water from the air before it enters your fluid system and remove particulate contaminants as small as 2 micron. The silica gel changes color as it becomes depleted, turning from gold to dark green.It’s easy to identify the condition of a breather and quickly replace it, maintaining the cleanliness of the fluid reservoir.

Two main threats to productivity: particulates and moisture

Most machine wear-related failures are due to particulate contaminants. As particles become airborne, they can enter lubricant and fuel reservoirs and then be transported to bearings, bushings, seals, hydraulic valves and other components. The contaminants cause lubricant degradation, reducing the service life of the lubricant.

With machine clearances measured in thousandths of an inch, it doesn’t take much contamination to affect bearings and other sensitive components. Even particles of 10 micron or smaller can disrupt the lubricant film and cause a great amount of wear.

Moisture is a continuous threat. Its presence in lubricants and hydraulic fluid creates a host of problems including rust, lubricant additive depletion, viscosity changes, oxidation and sludge formation.

A broad range of Air Sentry breathers is available to protect expensive equipment, increase operational efficiencies and reduce maintenance costs across a very wide range of application.
