Flow / Pressure Regulators

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.

External plastic tube with nut all graduations. Guaranteed French manufacturing

Delivery France and Europe in 48 hours.

Frosting issue on your Ar/CO2 regulator? The solution is to heat the gas to ensure a constant flow.

CO2 is a cold gas, and it needs to be heated for use in MIG welding protection.

Model with gas outlet under pressure, adjustable from 1-10 bar max. Equipped with a 125 W heater, powered by 220 V Single-phase.

Made in France by LE LORRAIN, 2-year warranty

Regulator for 10 Kg or 35 Kg PROPANE bottle, industrial type. Shielded model with a pressure setting up to 2.5 bar.

Ideal for feeding an oxy-propane or aero-propane cutting torch.

BESTSELLER product
