AFKLOK high purity (HP) pressure regulators have a gas purity of up to 6.0. Standard regulators do not meet this. They go mostly up to 4.0. For the production of HP regulators virgin material is used, Hastelloy diaphragms are used, special sealing materials are used, and surfaces are made extra smooth. It is suitable for a range of common industrial gases such as Hydrogen (H2), Methane (CH4), Carbon Dioxide (CO2), Oxygen (O2), Nitrogen (N2), Air, Helium (He), Argon (Ar), Nitrous Oxide (N2O) and many more.
