Function

The model 3004 is a Rapid Exchange® purging system that operates on a supply of compressed instrument air or inert gas.

The system regulates and monitors pressure within sealed protected enclosure(s), in order to remove and prevent flammable gas or vapor accumulations.

The system accomplishes the required volume exchanges and maintains a safe pressure. A Pepperl+Fuchs Model EPV-4 enclosure protection vent is required for proper operation.

This process reduces the hazardous (classified) area rating within protected enclosure(s), in accordance with the NEC - NFPA 70, NFPA 496, ISA 12.4.
