7500 Series Manual
4.2 EPV-7500 Vents
EPV-7500 vents work with the 7500 control unit and manifold to provide a functional, certifiable purge and
pressurization system for enclosures. As required by all pressurized enclosure systems, the EPV-7500 vent
functions as a pressure relief device and allows the purge gas to exit the enclosure, yet provides a seal
when the enclosure is pressurized and operating. The vent also has a spark arrestor, which is required for
hazardous areas.
