Pressure Relief Valves

Pressure relief dampers prevent the uncontrolled ingress or backflow of air. Pressure relief dampers (PRD) can be used wherever it is necessary to prevent the ingress or backflow of uncontrolled air. In many cases, these dampers are a cost-effective alternative to forced dampers. The pressure relief damper consists of a frame construction in which several aluminum slats are pivotally mounted around horizontal axes. The frames are designed as stop frames and as intermediate construction frames.
