## EVOS Multi-Stage Inert Gas Regulator for 300 Bar Cylinders

The **EVOS Multi-Stage Inert Gas Regulator** is designed for use with **high-pressure 300 bar EVOS cylinders**. Suitable for inert gases such as **argon and nitrogen**, this regulator provides stable and accurate outlet pressure for professional gas control applications.

It is ideal for use where consistent outlet pressure is required, including **quality cutting applications, laboratory systems, precision machine cutting and high-flow gas supply**. The multi-stage design helps maintain reliable pressure delivery, even as cylinder pressure decreases during use.

Built with a strong **barstock brass body** for maximum durability, the first stage reduces full cylinder pressure by approximately 90% before final pressure regulation. This makes it a dependable choice for demanding workshop, site and industrial environments.
