The principle of operation of Class II cabinets involves a fan mounted in the top of the cabinet that draws a curtain of sterile air over the workstation where the biological products are being handled. The air then moves underneath the work station and back up to the top of the cabinet b...
The Class II Type A2 biological safety cabinet is the most common Class II cabinet. It has a plenum from which 30% of air is exhausted, and 70% re-circulated to the work area as the downflow. Stated from NSF/ ANSI 49:2010, both the Class II Type A1 and Type A2 must have the pos...
A Class II, Type C1 cabinet must maintain a minimum average inflow velocity of 105 fpm through the sash opening. Type C1 cabinets are unique in that they can operate as either a Type A cabinet when in recirculating mode or a Type B cabinet when exhausting. C1 cabinets can be quickly chan...
