Duco Premium Invisible Air Valves

Product Part Number: 0000-4903

The award-winning Duco Premium Invisible Air Valve is the ultimate high-end, discreet, and ultra-quiet air valve designed to blend seamlessly into your ceiling. Once installed and plastered in, the trimless and recessed design ensures the valve remains virtually invisible, maintaining a sleek and modern aesthetic.

Using the Coanda effect, the air is diffused in a horizontal motion, preventing unwanted draughts and enhancing comfort in any indoor space. Extremely easy to install, this air valve comes complete with a plaster ring, reducing installation time compared to traditional gypsum-type trimless valves. It can also be retrofitted when replastering a ceiling.
