BOC EVOS Multi Stage Oxygen Regulator (4bar)

EVOS Multi-Stage Oxygen Regulator – 0–4 Bar / 0–10 Bar

The EVOS Multi-Stage Oxygen Regulator is designed for use with 300 bar EVOS oxygen cylinders where stable and accurate outlet pressure is required. Built for professional oxygen applications, it is ideal for quality cutting, laboratory systems, precision machine cutting and other high or stable flow requirements.

This regulator features a strong barstock brass body for maximum durability, with the first stage reducing full cylinder pressure by approximately 90% before final pressure control. The multi-stage design helps provide consistent gas delivery, making it suitable for applications where reliable oxygen pressure is essential.

Available in 0–4 bar or 0–10 bar outlet pressure options, this regulator is suitable for a range of controlled oxygen supply applications.
