6 Inflow is joined by half of the downflow, to create front air curtain that is fine-tuned to create a large performance envelope. The combined air stream travels through the back air column towards the blower. Approximately of the air in the common plenum is exhausted through the ULPA filter to the room. The remaining of the air is passed through the downflow ULPA filter and into the work area as a vertical laminar flow air to create ISO Class 3 work surface and prevents cross contamination. Near the work surface, the downflow splits. About half goes to the front grille, and half goes to the rear grille. A small portion enters the the side capture zones to prevent dead air corners (small blue arrows). The design was optimized to give large performance envelope, that provides operator and product protection at wide Inflow and Downflow variation from the Nominal Performance Envelope m/s504060708090100 fpm0 Downflow Velocity Nominal AirflowPersonnel / Product ProtectionInflow fpmArea of Personnel /Product ProtectionNo Personnel /Product ProtectionArea of no Personnel /Product , m/s(70, 105 fpm)1A.

8 1 / 17LB2 Class II TYPE B2 Biosafety CABINET7 Ambient air is pulled through the front grille to prevent contamination of the work surface and work product. The inflow does not mix with the clean air within the cabinet work zone. Ambient air is taken in through a pre-filter at the top of the cabinet, and passes through the downflow ULPA filter, entering the work zone as laminar flow. The uniform, non-turbulent air stream protects against cross contamination within and throughout the work area. Near the work surface, the downflow air stream splits with a portion moving toward the front air grille, and the remainder moving to the rear air grille. A small portion of the ULPA filtered downflow enters the intake perforations at the side capture zones at a higher velocity (small blue arrows). A combination of inflow and downflow air streams forms an air barrier that prevents contaminated room air from entering the work zone, and prevents work surface emissions from escaping the work zone.

9 The downflow combined with the inflow air enters the common air plenum. All air in the common plenum is HEPA-filtered and exhausted via a dedicated ducting system to the external environment.
