Thermal Efficiency and Structural Stability in One Panel
Backdraft Damper is ventilation accessory preventing air reverse flow inside air-duct systems. It stops reverse airflow from flowing back into upstream ventilation equipment or clean-room zones when fan unit stops running. It protects normal operation of purification ventilation systems, avoids polluted air back-flow contaminating clean-room interior environment. It can be installed inside static-pressure box or ventilation pipelines for purification projects.
Backdraft damper needs good sealing performance under back-pressure condition. Our production based on existing mature technical standards guarantees reverse-flow-blocking effect without extra brand-new product development.

Applications
Clean-room air-supply terminal ventilation system: Avoids polluted air flowing backward into clean-workshop space when ventilation equipment stops.
Exhaust-air pipeline for pharmaceutical factories: Prevents exhaust-gas reverse flow inside factory exhaust duct-work.
Laboratory ventilation pipeline: Blocks reverse-flow risk for lab exhaust and air-supply duct-net.
Food-factory workshop ventilation system: Protects clean-production zone from reverse-flow polluted air.
