Function: EPV-5500 Vent System

The EPV-5500 vent works with the 5500 control unit and manifold valve to form a certified purge and pressurization system for enclosures. It can not be used alone.

Vents are a required component for all pressurized enclosure systems. The EPV-5500 functions as a pressure relief device, allowing the purge gas to exit the enclosure and includes a spark arrestor. The vent also provides a seal when enclosure is pressurized and operating.

The 5500 series purge and pressurization system has NEC, CEC, ATEX and IECEx third part certifications for Class I, II/Div. 2 and Zone 2/22.
