Modern hospital hygiene focuses it's interests in air conditioning on a limited protection zone, in which airborne germs must be excluded rigorously from operation wounds, and in which patients may continue to pose concrete dangers.
The canopy is installed as a unit inside the suspended ceiling of the Operating Theatre and consists of an air outlet element, an anodized aluminium or stainless steal plenum with sound absorbers and air circulation modules.
The room air is taken in at the air circulation module, mixed in the module with the fresh air conditioned by the air conditioner, and discharged into the plenum chamber located above the filter canopy. The clean air, after filtering, then flows into the OT, and forms the protection zone. The ideal clean air outlet of the low-turbulence canopy possesses a uniform outflow area without dead zones, and peripheral skirting of laminated or safety glass or plexiglass that runs down to the height of the door lintels.
