RESULTS ACHIEVED DURING THE TESTS WITH THE PARTICLE COUNTER


FOUR MODELS FOR A GLOBAL PROTECTION


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).
