Tornado Dampers

These heavy-duty tornado dampers prevent the collapse of the ductwork during inclement weather. Installed in ductwork or wall mounted near the exterior of a building, the dampers allow for air movement (intake or exhaust) during normal conditions but close when they sense the negative pressure caused by a tornado.
