Environment Protection

  • Aeromech™ Class II Type B2 cabinet all inflow and downflow air is exhausted after HEPA filtration to the external environment without recirculation within the cabinet. Type B2 cabinets are suitable for work with toxic chemicals employed as an adjunct to microbiological processes under all circumstances since no re-circulation occurs. In theory, Type B2 cabinets may be considered to be the safest of all Class II biological safety cabinets since the total exhaust feature acts as a fail-safe in the event that the downflow and / or exhaust HEPA filtration systems cease to function normally. However, Class II Type B2 cabinets are, in practice,difficult to install, balance and maintain.

Aeromech™ make Biosafety Cabinets are designed for the safe handling of cytotoxic agents and other hazardous drugs in Pharmacy and Oncology settings. This biosafety chamber eliminates cross-contamination and accidental release of pathogenic microorganisms or carcinogenic aerosols to the outside environment.

Other applications include handling materials PS such as powders and allergens. The work area is bathed with a HEPA-filtered unidirectional (laminar) flow ISO 5/Class 100 air to protect the product Further, the exhaust air This Class Il, Type B2 Biological Safety Cabinet is a 100% Total Exhaust unit. The Exhaust must be ducted (vented) to the outside of the building as there is absolutely no recirculation of air in the cabinet. This total exhaust feature makes the B2 hood suitable for not only handling particulates, but also fumes and gases.
