Overview

A pressure relief damper protects a pressurized space from over-pressure. Its spring-loaded blades open automatically at a set pressure differential, adjustable and typically 12–50 Pa, and close tight under normal operating conditions, with low leakage when closed (Class 3 per EN 1751). It has a galvanized steel frame with aluminium or steel blades, in single or multi-blade configurations, and sizes from 300 × 300 mm to 900 × 600 mm.
