Committed to Product Innovation, Quality and Customer Satisfaction.

Metropolitan Air Technology (MAT), a U.S. based, ISO 9001:2015 certified company, has been manufacturing innovative air flow management products for over 20 years.

American Made. World Proven

MAT started with a unique line of remotely operated balancing dampers, designed to allow damper adjustment when gypsum (drywall) ceilings or high ceilings prohibit access to the ductwork. Over 500,000 of these dampers have been installed in some of the most prestigious buildings throughout the world, including office towers, residential towers, museums, hospitals, and hotels. MAT has since grown into a full service supplier offering a complete line of commercial dampers, blast dampers and pressure relief dampers.

Our history of innovation is complemented by our commitment to deliver value. Intelligent engineering increases the quality of our products, reduces costs, and provides value added performance or functionality to our customers.

We are a world-class HVAC supplier committed to customer satisfaction.


Our mission is to offer innovative air flow management products of the highest quality that deliver value to our global customer base of building owners, design engineers, and contractors. We will fulfill this mission through our commitment to product innovation and development, product and service quality, and a pledge to operate at the highest legal, ethical, and environmental standards.
