سیستم تصفیه و فشار pepperl+fuchs مدل 1002-WPSA-CI TYPE Y OR Z

The model 1002 is a Rapid Exchange® purging system that perates 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-2  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.
