Linde REDLINE Pressure Regulators C 300/1 & C 300/2

The REDLINE C 300 series pressure regulators (models C 300/1 single-stage and C 300/2 dual-stage) are designed for precise control of non-corrosive gases with purity levels up to 6.0 (99.9999%), as well as gas mixtures containing low concentrations of corrosive components.

Thanks to their robust design and high-quality manufacturing, these regulators provide excellent pressure stability, accuracy, and long-term reliability. They are particularly well suited for demanding laboratory, analytical, and research applications where maintaining gas purity and consistent pressure is critical.

The C 300/1 single-stage regulator is recommended for applications with relatively stable inlet pressure, such as gases supplied in liquid phase. The C 300/2 dual-stage version is intended for systems with fluctuating inlet pressure, ensuring highly stable outlet pressure and improved control under varying operating conditions.
