FOUR MODELS FOR A GLOBAL PROTECTION
Air Ceiling - Unidirectional ceiling air distribution system
STATIC CEILING WITH CRYSTAL CURTAINS
The curtains also contain a lighting (accessory) of the lamination system which gives a magnificent
indirect light effect. The curtains also serve the need of containing
laterally the air flow. The curtains are mandatory in case the tool beam
is needed.

STATIC CEILING WITH CRYSTAL CURTAIN AND TOOL BEAM FOR THE CONNECTION OF
SURGICAL INSTRUMENTS
The tool beam is needed to connect all surgical instruments; it therefore has electric socks,
movable tool carrying arms for the surgeon and anestisian and for the connection of the surgical
gasses. The height of the beam must be of at least 2 m from floor level so not do disturb the
surgeon.

VENTILATED CEILING WITH CRYSTAL CURTAINS
The recirculation fans are installed in the corners of the surgical room and are connected by ducts, downstream an F9 suction filtered grill installed in
the lower part of room and upstream the unidirectional cealing. The fans have an air flow of
approximately 2000 m3/h each. Upstream and downstream the fans sound dampers are installed which can guaranty that at a height of 1,7 m at the center of the room the sound pressure level does
not rise above 46 dB(A).
