What is the difference between Class II A2 cabinet and a Class II B2 Biosafety cabinet?

Airflow through a B2 is 100% externally exhausted which means the air that is drawn into the cabinet is 100% exhausted into the atmosphere. Whereas in A2 approximately 60% to 70% of its air is recycled after filtration.
