. . Reducer Mini CO2/AR 2 manometers is designed to reduce the outlet pressure of technical gas to the required working pressure. The reducing valve maintains a constant value of the outlet pressure regardless of the value of the inlet pressure.Reducer Mini CO2/AR 2 manometersFactory new. Pressure reducer equipped with two pressure gauges. The first indicates the pressure in the cylinder, and the second indicates the working pressure.Thread fits all commercially produced cylinders with an external valve.Outlet: female thread 1/8 inch (6mm stub included). Can be plugged in such a way that it does not additionally raise the height of the assembled set (cylinder + regulator). . . . . . A safety valve protects against exceeding the maximum pressure in the outlet chamber. The shut-off valve allows you to turn off the gas supply without turning off the valve in the cylinder. . . . Technical Parameters Inlet pressure (Mpa): 20Inlet thread: W 21.8x1/14Outlet threads: G 1/4Hose end: 6.3 mmCapacity (l/min): 20Gas type: Argon, Carbon DioxideGas gauge diameter: 50 mmSize dimensions L x W x H: 135x120x130 mm . .
