CONCOA 307 Series Regulator

CONCOA 307 Series Regulator

Four-Port, Chrome-Plated Brass Barstock, Rear-Entry Point-of-Use Regulator for High Purity Inert Gases

The CONCOA 307 Series regulator provides secondary pressure control for non-corrosive, liquefied, and ultra-high purity inert gases (up to grade 5.5). It is ideal for point-of-use pressure regulation in high purity gas distribution systems or for applications that can tolerate minor outlet pressure fluctuations due to diminishing supply or where inlet pressure is constant or below 500 PSIG (34 BAR). Rated to at least 3000 PSIG (210 BAR), the 307 Series rear-entry regulator is commonly used in laboratory installations and point-of-use panels.
