Operational Guidelines
Important Operational Note
This regulator uses a flow gauge which may become inaccurate if back pressure exceeds 2 PSIG. Back pressure is commonly caused by downstream restrictions such as metering valves, kinked hoses, or excessively long hoses. In environments where back pressure is likely, utilizing a regulator equipped with a flow meter is recommended to ensure accuracy.
Suitable Applications
- CO2 applications (non-siphoned tube cylinders)
- High flow CO2 applications
- Core wire applications
