Airstream® Class II Type B2 (Total Exhaust) Biological Safety Cabinets

Airstream® Class II Type B2 (Total Exhaust) Biological Safety Cabinets

Class II Type B2 biological safety cabinets provide product, operator and environmental protection and are suitable for work with trace amounts of toxic chemicals and agents assigned to biological safety levels I, II or III. In a Class II Type B2 cabinet, all inflow and downflow air is exhausted after HEPA/ULPA filtration to the external environment without recirculation across the work surface.

Key Benefits:
  • Energy-saving
  • Ergonomic design
  • Dynamic Chamber™ plenum design for quiet, uniform airflow
