Airflow Patterns
Figure 2-1
All Logic Type A2 cabinets meet the airflow
requirements of ANSI/NSF Standard 49:2007.
Approximately 55-60% of the air in the cabinet
is filtered and recirculated, while 40-45% is
filtered and exhausted. ALL Logics feature
intrinsically safe designs, jacketing
contaminated positive pressure areas with
negative pressure zones.
Figure 2-2
All Logic Type B2 cabinets meet the airflow
requirements of ANSI/NSF Standard 49:2007.
All of the air in the cabinet is filtered and none
is recirculated. ALL Type B2 Logics feature
intrinsically safe designs, with all contaminated
areas under negative pressure.
