Selecting a pressure relief damper

Select a pressure relief damper for the application it is intended to serve. PRD61 provides pressure relief in HVAC systems, while PRD200 is intended for stairwell pressurisation systems. Check the required relief airflow, opening-pressure setting, installation orientation and available space against the chosen model’s catalogue. Pressure relief and reverse-airflow prevention are different selection tasks; confirm the required function before comparing models.
