Gas Cylinder Filling Machine for Refilling Gas

Gas cylinder filling machine can complete compressing gas and filling gas into cylinder in one go. The gas filling machine is powered by compressed air, no electric spark and flame risk, thus explosion proof. For permanent gases or compressed gases such as oxygen, hydrogen, nitrogen, helium, natural gas and biogas, the gas filling is pressure-based. And the gas filling pressure cannot exceed the nominal working pressure of your gas cylinder. We supply manual and automatic gas filling machines for your choice. You only need to set a gas filling pressure, and the machine will automatically complete gas compression and gas refilling. And it will automatically stop filling when reaching your preset pressure, thereby avoiding gas excessive filling.

Gas Cylinder Filling Machine Features

  • Pneumatic operation ensures explosion proof
  • Safely compress gas and fill various gases into gas cylinders
  • Gas filling pressure up to 300bar and pressure adjustable
  • Automatic stop at preset pressure avoids overpressure
  • Manual and automatic gas filling machines optional

Gas Refilling Machine Applications

  1. Serve as an oxygen tank refill machine to fill oxygen in cylinders.
  2. Act as a CNG filling machine to compress natural gas and fill natural gas in cylinders.
  3. Used for biogas cylinder filling machine to compress biogas and fill it in cylinders.

How Gas Cylinder Filling Machine Works

Gas cylinder filling machine can complete compressing gas and filling gas into cylinder in one go. We offer manual and automatic gas filling equipment for your choice. For manual gas filling machine, you need to manually set a gas filling pressure by adjusting the air regulator while observing the pressure gauge on panel. For automatic gas filling machine, you only need to click the touch screen to set a gas filling pressure. Then the machine will compress gas and fill gas into cylinder. And it will automatically stop filling when when reaching your preset pressure, thereby preventing excessive filling gas.

Gas Filling Pump

If your budget is limited, you can purchase just gas filling pump to achieve compressing gas and filling gas. The gas filling pump, as known as a gas compressor pump, is actually a gas booster. By adding an air regulator and a pressure gauge, you can build a low-cost basic gas filling system by yourself. First of all, you need to set a gas filling pressure by adjusting the air regulator while observing the pressure gauge. Then the gas filling pump will compress gas and fill gas into your cylinder, and it will stop automatically when reaching your set pressure, thus avoiding excessive filling gas.

Frequently Asked Questions

What is the gas filling pressure?

The gas filling pressure depends on your cylinders. The most common pressure ratings for steel cylinders on the market are 15MPa and 20MPa.
