Single stage regulators have pressure rise of approximately 1/2 psi (.5) per 100 psi drop in cylinder pressure

Maximum flow = 6300 SCFH, Free air @ 70°F, no flow restrictions

Note: The standard cubic foot per hour flows are obtained with the regulator outlet full open with no restrictions; using a preset outlet pressure and with decreasing cylinder pressure

PSIG – Pounds per sq. in. gauge

SCFH – Standard cu. ft. per hour

Note: PSI/kPa, PSI/Kg, PSI/BAR gauges are available
