Gentec 155TQ-200 Two Stage Air Regulator CGA346

Product Description

The GENTEC 155TQ-200 is a two-stage extra heavy duty compressed air regulator designed to deliver consistent outlet pressure from high-pressure cylinder sources. Two-stage regulation reduces the pressure drop in two steps, resulting in a more stable and accurate delivery pressure compared to single-stage designs. The CGA346 inlet connection is the standard fitting for compressed air cylinders, making this unit compatible with typical shop and industrial air supply setups. Licensed technicians and industrial gas professionals install this regulator when consistent flow and pressure stability are required across demanding applications.

This regulator is suited for professional and industrial compressed air service where supply pressure from the cylinder can vary significantly over time. Two-stage units are commonly specified in applications requiring steady regulated output, such as instrument air supply, pressure testing, and similar trade or light industrial work. The extra heavy duty construction indicates it is intended for higher-demand environments rather than light-duty or intermittent use.

Key Features

• Two-stage pressure reduction for stable, consistent outlet pressure
• Extra heavy duty construction rated for demanding industrial and trade use
• CGA346 inlet connection matches standard compressed air cylinder fittings
• Reduces downstream pressure fluctuation as cylinder supply pressure drops

Compatibility

Designed for use with compressed air cylinders equipped with a CGA346 valve outlet. No additional model-specific compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed gas equipment and applicable safety codes. Fully depressurize and isolate the cylinder before attaching or removing the regulator. Inspect the CGA346 inlet connection and cylinder valve seat for damage or debris before making the connection, and never use pipe thread sealant or PTFE tape on CGA fitting threads. Verify that downstream equipment pressure ratings exceed the regulator outlet pressure before placing the system in service.
