The outlet pressure is preset at 3.5 bar as standard and the flow is set on a ten position selector, 0.3 to 3 l/min on the B03 version or 0.5 to 5 l/min on the B05, and the piston holds that flow steady as the cylinder empties from a 200 bar fill. At 0.7 kg it is built to travel with the cylinder. The inlet is C10 or 1/4 in NPT, the outlet a hose barb, DR 6 or 1/4 in tube fitting, with a high pressure gauge on a 1/8 in NPT port and an integrated safety valve. The body is nickel plated brass with a Hastelloy piston, PCTFE seat gasket and FPM O-ring, oxygen use is on the brass body only, and the helium leak rate is 1 x 10-4 mbar l/s.
