The operating theatre ceiling is the most important part of a hospital ventilation system. Also called UCVS (Ultra Clean Ventilation System), these sophisticated systems are actually a combination of a variety of elements, including gas tight welded pressure chambers, air filter housings or filter grids, HEPA filters, priming illumination and air diffusers.
Laminar Flow Ceiling for Operating Theatres
