Main pressure reducer Vulkan H60/300 Effect nitrogen DIN 477-5, 0-60 bar, 140 Nm³/h according to DIN EN ISO 7291, single-stage design, with pre-pressure compensation for constant back pressure with falling pre-pressure, with safety pressure gauges according to DIN 562. Maximum inlet pressure: 300 bar. Output pressure: 0-60 bar adjustable. Maximum output: 140 Nm³/h compressed air at 60 bar back pressure. Inlet: W30x2RHf U-nut according to DIN 477-5, Outlet: G 1/2 RHak according to DIN EN 560. Inlet pressure gauge: 0-400/300 bar. Outlet pressure gauge: 0-100/60 bar. Width x height x depth: 210 x 190 x 75 mm. Important note for 300 bar pressure reducers - please check your bottle connection! Cylinder pressure regulators for 300 bar have a manual connection according to DIN 477 Part 5 and are NOT backward compatible. This means they do NOT fit cylinders with a maximum filling pressure of 200 bar! If necessary, see our following tutorial, 3: Difference between 200 bar and 300 bar pressure regulators.
