1004 Series purge and pressurization system

Function

The model 1004 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 four air exchanges and maintains a "safe" (0.25") pressure. A Pepperl+Fuchs Model EPV-4 Enclosure Protection Vent
is required for proper operation.
This process reduces the hazardous (classified) area rating within the enclosure(s), in accordance with the NEC - NFPA 70, Article 500,
NFPA 496 and ISA 12.4.
