Plenum Unit (Laminar Air Flow)
The ceilings consist of a plenum box supplied with conditioned air from the central system via HEPA filters mounted on the inlet to the supply ceiling.
All HEPA filters and housings are factory tested and certified in accordance with DIN:1946 and DIN:4799. All ceilings incorporate supports to secure them to the main structural frame of the modular operating theatre, or structural slab.
