It is characterized by a limited fixed inward Air Flow access opening that provides personnel protection, a vertical downward HEPA filtered work zone that provides product protection and HEPA filtered exhaust providing environmental protection. A Type A2 cabinet maintains a minimum of 100 FPM inflow velocity, self-exhausts approximately 30 percent back into the laboratory, and recirculates the remainder. |
