About Us

Headquartered in Rockwall, Texas, Air Sentry® is a global leader in developing and manufacturing state-of-the-art contamination control products. Our products are considered the gold standard in contamination control and are used worldwide in major industrial, mining, military, power generation and fluid storage applications.

Air Sentry Breathers were introduced in 1997 to satisfy an obvious and growing requirement in industry—to increase fluid cleanliness, thus decreasing skyrocketing maintenance costs and equipment failure. Air Sentry was a finalist in Plant Engineering's Product of the Year in 1999 and 2003 for innovative developments in breather technology.

With multiple product lines that maintain an outstanding level of quality, we continue to advance the fight against contamination. Air Sentry breathers are manufactured under strict ISO 9001 and ISO 14001 Certified Quality Systems in the United States. Our products are available around the world through a service-intensive distributor network committed to technical support and total customer satisfaction.
