FLOW ACTIVA_VF e VE Standard e Plus (vertical laminar flow)


The cabinet FLOW ACTIVA VF has been developed for the comprehensive protection of operator, product and environment during the manipulation of microorganisms at low biological risk (category 1 and 2).

In Flow Activa, Class II Type A1 and A2 (ex A and B3), the decontaminated air from the HEPA filter of downflow goes down with laminar flow into the work area, crosses the plan, is mixed with outdoor air, that enters into the cabin through the front opening in the front area of the worktop. The contaminated air is aspirated from the fan motor at the top of the cabin and conveyed into a plenum: here about 70% is sent again into the working area with absolute filtration and the remaining 30% is expelled to the outside, directly (in Standard models) or after absolute filtration (in Plus models).
The quantity of expelled air is replenished with an equal amount of ambient air asucked through the front opening, creating a barrier to protect the operator.

Flow Activa plus VF e VE 120 - 150 e 180 are Biohazard models and they have TUV certification according to UNI EN 12469 (cert. n° ZI 10 09 62765 004 e n°Z1 10 09 62765 003)
