Main regulator Helium 0-20 bar Vulkan H20/300 Effect

Main pressure reducer Vulkan H20/300 Effect Helium DIN 477-5, 0 - 20 bar 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 EN ISO 5171. Maximum inlet pressure: 300 bar. Output pressure: 0 - 20 bar adjustable. Maximum output: 75 Nm³/h air at 20 bar back pressure. Inlet: W30x2RH U-nut according to DIN 477-5. Outlet connection: G1/2RHak according to DIN EN 560. Inlet pressure gauge: 0 - 400 / 300 bar. Outlet pressure gauge: 0 - 40/20 bar. Width x height x depth: 200 x 190 x 75 mm. Important note for 300 bar pressure reducers - please check your cylinder 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.
