A clear and thorough concept to comply with the latest air conditioning medical guidelines and norms for operating theatres characterises the media bridge OP 3800. A disruption and turbulence-free Laminar-Air-Flow from the ceiling air supply system up to a height of 2,100 mm from the floor can be realised with the medical supply unit designed for these purposes. In order to achieve this, the OP 3800 is equipped with an all-round flow of air fromthe ceiling connections to the top edge of the media bridge. As an option to the four-sided standard version, the OP 3800 can also be designed as an L– or U–shaped supply unit. In addition to the above, tapping points for the operation of surgical tools (Air-Motor) and anaesthetic gas scavenging system (AGSS) can be installed in the media bridge on the corresponding anaesthetic and surgery-facing sides as the project requires.
