00214EN Rev.05 - CytoFAST Elite - Wolf Laboratories

a D:GROUP company
3 OPERATION PRINCIPLES
The following are the working principles of the CYTOFAST ELITE-cabinet :
the pressurized air pushed into the plenum of the main motor-fan passes through the absolute filter and then
downwards, in laminar flow, into the working chamber (A). From here, through the slots of the work surface,
having mixed with the external air (B) which enters the cabinet from the front opening, the air passes through
the absolute filter placed under the work surface (C) and is sucked into the intake up channel situated at the
rear of the working area (D). Part of the air (E) is extracted by the second motor-fan through the
corresponding absolute exhaust filter. This extracted air generates the intake of air from the outside (front
barrier) which ensures the protection of the operator/environment from hazardous material manipulated in the
working area.
The extracted air may be filtered again through a second absolute exhaust filter placed on the exhaust duct of
the cabinet (BS 5726), if the air is recycled inside the laboratory where the cabinet is installed.
