The neutral gas large flow pressure regulator allows a standard pressure to deliver from 20 to 280 NM3/H. It can be used as a first pressure regulator, in neutral gas, to supply several dozen welding stations.

It is recommended to mount this regulator only on bottles of B50 = 10 m³ or on bundles of bottles.

Second stage pressure regulator for neutral gases (nitrogen, argon) suitable for applications using pure and inert gases. 

Equipped with a stainless steel diaphragm, output pressure adjustment from 0-35 bar.

Allows a very stable output pressure and a very precise adjustment.

Perfect for feeding laser cutting machines.
