BIO II Acabinet provides personnes, environmental and product protection in applications involving biological agents. These cabinets have been designed according EN12469 and are meeting or exceeding requirements of NSF49, BS5726,NFX 44-201 and DIN 12950.
Each cabinet is factory-certified by TUV-GS registered laboratory to meet the specified performance requirements.
Control System
Main swith with key and microprocessor control system. Alphanumeric luminescent display providing following data:
-Exhaust air flow m/h
-Cabinet temperature C
-Fans elapsed hour meter
-U.V.lamp elapsed hour meter.
-HEPA filters last change date
Safety and regulation systems controlled by the microprocessor. Visual and auditory alarms shown on the display.
-Low exhaust flow.
-Low downflow air velocity
-Exhaust fan malfunction.
-Front window oepned.
Control system is also providing safety features as:
-U.V. interlocking when front window is open.
-Air flow and lighting interlocking when U.V. lamp is on.
-Impulsion and exhaust fans providing a double safety system: incase of eventual stop of the exhaust fan, the impulsion one is automatically stoppped. In case of eventual stop of the impulsion fan, the exhaust one increases its speed in order to maintain underpressure conditions in the working space.
-Microprocessor compenstates for gradual increase in filter resistance:inflow and downflow are maintained in any condition.
BIO II A cabinet is 70% recirculating down flow enclosure calss II a/b3 equippen with two high efficiency HEPA filters:
-HEPA filtered laminar airflow Class 10, which is recirculated in the work zone , creates an ultra clean work enviornment for product protection. A room air barrier at the front opening prevents escape of pathogens into the worker''s area.
-Exhaust HEPA filter provides safety to environment.
-Stove-enamel coated steel cabinet .Easy access for working and cleaning .Working space in stainless st AISI 304. Segmented working surface. Laminated safety front window with gas spring .Two HEPA/ULPA filter stages H14 efficiency with gas springs. Two HEPA/ULPA filter stages H14 efficiency 99.999% for particles >0.3 u easily accessible for replacement.
Vertical down flow filter exhaust filter and fans accessible from the front provide easy maintenance.
Lighting system outside working chamber makes service easier.
Possibility to connect remote fan in ducted cabinets.
Special model with lead protection for radioisotopes preparation.
