Product HighlightsThe model PRD-RD pressure regulating dampers is a single blade round barometric damper assembly with a counter balanced weighted arm. The barometric by-pass damper is an economical way to manage airflow when zone dampers close. Damper adjustment is achieved by off-setting the hex shaped arm, securing weight #1 towards the bottom of that arm and moving the extra weight(s) (optional) up or down the arm, until the correct bypass flow is achieved.
