Bio Safety Cabinet Class II B2

Labvent Class II Type B2 Biological Safety Cabinets

In the case of Airmac Class II Type B2 cabinet all inflow and downflow air is exhausted after HEPA filtration to the external environment without recirculation within the cabinet. This means that Type B2 cabinets are apt for working with toxic chemicals employed as an adjunct to microbiological processes under all conditions since no re-circulation occurs. In theory, Type B2 cabinets may be measured 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, in practice, are difficult to install, balance and maintain.
