Pressure relief damper:In order to prevent contamination of the cleanroom, it is necessary to maintain positive pressure indoors. If the pressure inside the cleanroom is too high, causing the door to be difficult to open and close, a pressure relief damper is used to maintain a slight positive pressure inside the cleanroom. The air volume through the pressure relief damper is generally between 100-1200m3/h, and the pressure difference is maintained between 5-40pa.

★Close tightly and respond sensitively;

★Easy to adjust and aesthetically pleasing in appearance;

★Not consuming energy;

★The exhaust wind speed does not affect the indoor airflow state;

★The position of the heavy hammer can be adjusted according to the requirements of air volume and pressure difference.
