2.4. EPV-5500 Vents

EPV-5500 vents work with the 5500 control unit and manifold to provide a functional,
certifiable purge and pressurization system for enclosures. As required by all
pressurized enclosure systems, the EPV-5500 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.
