The Metal Round Pipe Backdraught Shutter 400mm effectively stops reverse airflow in ducting systems, helping maintain indoor air quality and ventilation efficiency. Constructed from robust metal, it is built to withstand continuous use in demanding commercial environments.
With its 400mm diameter, this shutter automatically opens with active airflow and closes when the system stops, preventing drafts, odours, and contaminants from entering the ducting.
Ideal for HVAC systems in offices, factories, and other commercial settings, this backdraught shutter ensures reliable airflow control and long-lasting performance.
