BIO VE
The BIO ACTIVA VE hood has been developed for the global protection of operator, product and environment during the manipulation of pathogenic material.
The biohazard hood, in Class II type A1 and A2 (ex A and B3) has a front opening with air inlet from outside to inside, vertical laminar air flow inside the cabin and HEPA filter in Exit.
As required by the regulations in force the air decontaminated by the absolute filter descends vertically with laminar flow in Class 100 on the work area and crosses the plane. The contaminated air is sucked by the fan placed in the upper part of the cabin and conveyed in a plenum: here about 70% is sent again to the work area with absolute filtration while the remaining 30% is expelled to the outside (thanks to the Plus model to a second fan motor that is absent in the Standard model), after absolute filtration. The mass of air sucked in and recycled by the main fan keeps the recovery channel in negative pressure. The expelled air is reintegrated with an equal amount of ambient air sucked in through the front opening, creating a front insulation barrier in the area of access to the work area.
The Bio Activa VE 120 - 150 and 180 models are TUV certified according to the UNI EN 12469 standard (certificate No. ZI 10 09 62765 004 and No. Z1 10 09 62765 003)
