Backdraft damper based on gravitation actuation is designed for automatic duct shutoff and preventing air back draft.
The casing and the rotary vane are made of galvanized sheet steel. The rubber seals provide airtight connection to the air ducts. The vane is opened by means of air flow and is closed automatically at no flow. The damper lever is equipped with a counter balancing weight to regulate the sensitivity of the damper opening/closing.
The damper design ensures its mounting on the round ducts by means of clamps. The vane shall be gravitationally closed. While mounting the damper in the ventilation system consider the air stream direction.
