Product overview

What it is and where it fits.

A pressure relief damper opens automatically when a room's pressure rises above a set level, releasing excess air to an adjacent space. It keeps the pressure cascade between cleanroom zones stable and protects doors and walls from over-pressure.

Yiding dampers have painted steel or stainless steel bodies with aluminium blades, in 460 × 260 mm and 600 × 400 mm sizes.

FAQ

Common questions.

Why do cleanrooms need pressure relief dampers?

Cleanrooms are kept at higher pressure than surrounding areas so air flows outward. A relief damper releases excess air so the pressure difference stays within the design range when doors open or airflow changes.
