2.4. 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, while still providing a seal when
the enclosure is pressurized and operating. The vent also has a spark arrestor, which
is required for hazardous areas.
