      Dayton® backdraft roof dampers are used with roof and wall ventilators to close off systems when they are not in use. They help keep outside air from entering through ventilators when not in use.

      No Flange, Horizontal or Vertical MountThese non-flanged exhaust backdraft dampers are equipped with a felt seal on the leading edge of each blade for quiet closing and optimum weather protection. They are also spring assisted, allowing blades to open quickly. Use in roof curbs, duct work, or wall collars when using a fan or power roof ventilator.

      Roof Mount, Exhaust Each of these rear-flanged gravity supply (intake) wall shutters features mill-finish aluminum frame and blade construction, with a galvanized reinforcement strip on each blade for added strength and counter balancing efficiency.

The blades will pivot at the bottom and fall with gravity to open. Spring-assist to close.
