The Envair Bio 2+ provides clean air conditions over the work area as well as microbiological safety for the handling of biological agents up to and including ACDP Hazard Group 3 (subject to proper sitting, operation and maintenance) and has the following features:
| D | The Bio 2+ D is designed to exhaust HEPA filtered air to atmosphere via a dedicated ducting system and remote mounted extract fan |
| DB2 | 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 a dedicated ducting system and remote mounted extract fan. (B2 is the American NSF49 designation for 'Total Exhaust' class II microbiological safety cabinets) |
| DRS | The Bio 2+ DRS is similar to the Bio 2+ D but is generously sized and has additional features in order to accommodate Robotic Samplers and other equipment that might require Class II protection |
| R | The Bio 2+ R is designed to exhaust HEPA filtered air back to the laboratory via a dual in line HEPA filter and an integral exhaust fan |
| RRS | The Bio 2+ RRS is similar to the Bio 2+ R but is generously sized and has additional features in order to accommodate Robotic Samplers and other equipment that might require Class II protection |
| RD | The Bio 2+ RD is designed to exhaust HEPA filtered air into a thimble extract system (provided by the client) via a dual in line HEPA filter, an integral exhaust fan and a special exhaust spigot. A thimble extract system takes the exhaust of a microbiological safety cabinet into a specially designed room extract in such a way that the volume of air taken out of the room remains the same whether the cabinet is working or not |
