Exhaust System Requirements
The exhaust system must be capable of moving the following volumes of exhaust air at
the negative pressures listed. The
Airflow Volumes are the values recorded via direct
measurement using a flow hood at the front opening of the cabinet. The Concurrent
Balance Values are measured in the exhaust duct via traverse methodology, and will
always be higher due to differences in volume measurement methodologies.
For Type A2 models with Ventus Canopy Connections, see Table 7-1.
For Cell Logic+ Type A2 models with Ventus Canopy Connections, see Table 7-2
For Type B2 models, see Table 7-3.
For Type C1 models operating in B-mode, see Table 7-4.
