Smoke extraction dampers for shafts

Smoke extraction dampers for shafts are used for removing smoke and toxic gases generated during a fire. They are installed in the shafts of buildings to extract smoke and gases. The blades are usually in a closed position, but in the event of a fire, they open to allow the removal of smoke and toxic gases. Versions are available for installation in both shafts and ducts. The body is made of galvanized sheet metal with a thickness of 1.5 mm, and the blades are made of aluminum profile or galvanized sheet metal. These valves are suitable for motorized control.
