Victor® SR311 CO2 Regulator/Flowmeter 0781-0353

The SR311-320 CO2 Flowmeter regulator is designed for use with standard (non-siphoned) carbon dioxide (CO2) cylinders where high flow rates cause other regulators to freeze up. The SR311 design incorporates aluminum heat sink fins which permit high flow rates without freeze-up or noticeable change in pressure or flow by significantly increasing the surface area of the regulator. The fins help dissipate the cold, without the use of electricity.

Designed for CO2 application (gaseous, non-siphoned tube cylinders)
Designed for core wire applications
