Theory of Operation

This section offers a brief overview of the theory of operation of the Logic+.

Airflow Patterns

Figure 1-8

All Logic+ Type A2 cabinets meet the airflow

requirements of ANSI/NSF Standard 49:2012.

Approximately 55-60% of the air in the cabinet is

filtered and recirculated, while 40-45% is filtered and

exhausted. ALL Logic+s feature intrinsically safe

designs, jacketing contaminated positive pressure

areas with negative pressure zones.

Figure 1-9

All Logic+ Type B2 cabinets meet the airflow

requirements of ANSI/NSF Standard 49:2012. All of

the air in the cabinet is filtered and none is

recirculated. ALL Type B2 Logic+s feature

intrinsically safe designs, with all contaminated

areas under negative pressure.
