WebTraditional Class II BSC designs use single fan systems that, are generally able to maintain total airflow but not the balance of inflow and downflow. Should the downflow and exhaust filters load at different rates, the inflow could steadily increase while the downflow steadily decreases (Figure 2: High inflow / low downflow). WebBefore a BSC leaves the NuAire factory it will go through testing that includes airflow balancing placing the workable sash height at the level you requested 8, 10, or 12 inches (203, 254, or 305 mm). ... The accuracy of this biosafety process depends on the cabinet maintaining a balance between inflow and downflow velocities. When working ...
