American Made. World Proven.
M.A.T. 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. M.A.T. has since grown into a full service supplier offering a complete line of commercial dampers, VAV terminal units and comfort control systems. M.A.T. is now also a blast damper manufacturer as well as supplier.
