3000 Series
Type Y/Z and Ex pz certified

Our Pepperl+Fuchs 3000 series, Type Y/Z purging system will purge & pressurize the protected enclosure & maintain pressure within the enclosure. The system will reduce the classification within the protected enclosure from either: Division 2 to a non-hazardous area, Division 1 to a Division 2 location, or Zone 2 to a non-hazardous area.

Model 3003 is a Rapid Exchange® purging system that operates on a supply of compressed instrument air or inert gas. It regulates and monitors pressure within sealed protected enclosure(s), in order to remove and prevent flammable gas or vapor accumulations. The Model 3003 consists of four major components: (1) a pneumatic manifold assembly, (2) a differential enclosure pressure indicator, (3) a stainless steel face plate with mounting flange, or a Lexan® system start up instruction nameplate, and (4) an Enclosure Pressure Vent. Model 3003 is offered in three distinct variations, identified as "VM" (Vertical Mount), "HM" (Horizontal Mount), and "CK" (Component Kit mounting configurations. Optional pressure switches are available for all models.
