Large zone ducts need a damper to match, and this 400mm unit is opened or closed by the zone controller to send air only where it is needed. The 24V motor drives the blade both open and closed, the folded metal blade carries a 12mm foam seal, and the galvanised barrel has 5mm silver insulation.
Check that your zone controller supports 24V drive open, drive close dampers. Measure the duct to confirm 400mm and plan the control cable route. Hang the damper so it is supported on its own, fit the duct to both ends with straps and tape, and leave access to the motor for service.
