Gelman Besaire Class II Type B2 (Total Exhaust) Laminar Flow Biological Safety Cabinets are 100% Total Exhaust cabinets designed to provide a high degree of personnel, environment and product protection in applications involving low to moderate risk biological agents that require Biosafety Level 1, 2 or 3 containment.
The cabinets may be used for work with biological agents that have been treated with toxic chemicals and radionuclides required as an adjunct to microbiological studies.

Gelman Besaire Class II Type B2 Series cabinets maintain a minimum average inflow velocity of 100 fpm through the work access opening.
Ambient air is drawn in through a prefilter on top of the cabinet and is introduced to the work area through a supply HEPA filter that creates a biological-clean work environment for product protection.
An effective air barrier between the operator and the work zone, maintained by an inflow of room air into a full-width front grille in the work opening provides personnel and environment protection.
The barrier air blends with the contaminated work area air in a sump beneath the work surface and is totally exhausted to the outside atmosphere via a dedicated facility exhaust system after HEPA filtration, without recirculation in the cabinet or return to the laboratory.
The GELMAN ZERO-LEAK airflow system ensures that all positive pressure zones are surrounded by negative pressure zones to contain potentially-hazardous aerosols.
