• Mobile carbon filter unit • H202 vapour phase biodecontamination system including connections and sealing valves • 5m fumigant extract flexible duct including connection • Auto-purge to allow full automatic fumigation cycle • Integral Formalin Vapouriser with auto timer and exhaust sealing valve • Integral Formalin Vapouriser with auto timer Fumigation Options Note: When a formalin vaporiser is fitted to a recirculating (R or RRS) cabinet, it must be used either in conjunction with the 5m fumigant extract flexible duct including connection (if there is a window or fume cupboard nearby through which it can exhaust) or with the Mobile carbon filter unit. Useful Information - Definitions BS EN 12469 2000 Microbiological safety cabinet (MSC): Ventilated enclosure intended to offer protection to the user and the environment from the aerosols arising from the handling of potentially hazardous and hazardous micro-organisms, with air discharged to the atmosphere being filtered. MSC Class I: Safety cabinet with a front aperture through which the operator can carry out manipulations inside the cabinet and which is constructed so the worker is protected and the escape of airborne particulate contamination generated within the cabinet is controlled by means of an inward airflow through the working front aperture and filtration of the exhaust air. MSC Class II: Safety cabinet with a front aperture through which the operator can carry out manipulations inside the cabinet and which is constructed so the worker is protected, the risk of product and cross contamination is low and the escape of airborne particulate contamination generated within the cabinet is controlled by means of an appropriate filtered internal airflow and filtration of the exhaust air. NOTE A typical way of achieving this is by means of a unidirectional downward laminar airflow inside the cabinet and an air curtain at the front aperture. MSC Class III: Safety cabinet in which the working area is totally enclosed and the operator is separated from the work by a physical barrier (i.e. gloves mechanically attached to the cabinet). Filtered air is continuously applied to the cabinet and the exhaust air is treated to prevent release of micro-organisms. ACDP (Advisory Committee for Dangerous Pathogens) Hazard Group 1: A biological agent unlikely to cause disease. Hazard Group 2: A biological agent that can cause human disease and may be a hazard to employees; it is unlikely to spread to the community and there is usually effective prophylaxis or effective treatment available. Hazard Group 3: A biological agent that can cause severe human disease and presents a serious risk to employees; it may present a risk of spreading to the community, but there is usually effective prophylaxis or treatment available. Hazard Group 4: A biological agent that causes severe human disease and is a serious hazard to employees; it is likely to spread to the community and there is usually no effective prophylaxis or treatment available.

BIO 2+ MODEL DESIGNATIONS The Bio 2+ D is designed to exhaust HEPA filtered air to atmosphere via a dedicated ducting system and remote mounted extract fan. Airflow Diagram The Bio 2+ DB2 is a ‘Total Exhaust’ cabinet and 100% of the combined volume of the inflow and downflow air is exhausted via a HEPA filter to atmosphere via DB2 a dedicated ducting system and remote mounted extract fan. (B2 is the American NSF49 designation for ‘Total Exhaust’ class II microbiological safety cabinets). The Bio 2+ DRS is similar to the Bio 2+ D but is generously sized and has DRS additional features in order...
