Welcome

Air Sentry® Contamination Control Breathers are used worldwide in major industrial, mining, military, power generation, and fluid storage applications. They remove water, solid particles, and other contaminants from air being breathed into reservoirs, transformers, storage tanks, and gearboxes. The service life of equipment and fluids is greatly extended when protected by an Air Sentry® Breather. Most gearboxes, transformers, and hydraulic reservoirs have a simple breather/filling cap that allows air to be breathed in and out as fluid levels change or temperatures increase or decrease. Standard breather caps do not stop water vapor and other harmful contaminants from entering the system.
