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. - Page 24 15 scfh (424 l/hr) at 0.25 in wc (0.63 mbar) approx. 25 scfh (707 l/hr) at 0.75 in wc (1.9 mbar) Breaking pressure EPV-7500-...-01: 0.8 in wc (2.0 mbar) EPV-7500-...-02: 1.4 in wc (3.5 mbar) EPV-7500-...-03: 1.5 in wc (3.8 mbar) EPV-7500-...-04: 1.4 in wc (3.5 mbar)
