Blast Dampers

The blast dampers manufactured by M.A.T. are designed to protect equipment and personnel against blasts and instantaneous pressure changes from industrial vapor cloud explosions. Typical applications are the protection of the air intake/exhaust openings and building vent openings, and for protection and exhaust in fire suppression systems (when coupled with our BD-200-HD fire resistant pressure relief damper). Typical building spaces are control & instrumentation rooms, and sub-stations. M.A.T. blast dampers can be surface mounted to exterior walls and roof structures or duct mounted.
