Pressure Relief Damper
Product Overview
A Pressure Relief Damper is a critical differential pressure control component for cleanrooms and positive/negative pressure isolation spaces. It automatically opens when space pressure exceeds the setpoint (typically 10–25 Pa), preventing system over-pressurization that could cause door seal failure, filter damage, or AHU malfunction. Using gravity or spring-balanced designs, it operates passively without power, with sensitivity adjustable to on-site pressure requirements. Suitable for pharmaceutical GMP, hospital negative-pressure wards, semiconductor cleanrooms, and BSL biosafety laboratories.
