The 307 Series regulator provides secondary pressure control of non-corrosive, liquified, and high purity (up to grade 5.5) inert gases. The regulator is also suitable for point-of-use pressure control in high purity gas distribution systems or applications that can tolerate fluctuations in outlet pressure due to diminishing inlet supply or where inlet pressure is constant or under 500 PSIG (34 BAR). Like almost all CONCOA regulators, the maximum inlet pressure for the 307 Series regulator is at least 3000 PSIG (210 BAR) or greater, depending on system configuration. The CONCOA 307 Series rear entry regulator is often used on point-of-use panels and laboratory installations.
