Oxygen (O₂)

The oxidizing gas used for life sustaining and performance optimization applications

Oxygen is a colorless, odorless reactive gas and the life-supporting component of air. It forms just under 21% of the earth's atmosphere, and is the most abundant element in the earth's crust, mainly in the form of oxides, silicates, and carbonates.

In addition to its use as a respiratory gas for healthcare applications, oxygen has strong oxidizing properties that can benefit many industries by improving yields, optimizing performance, lowering costs and reducing carbon footprint compared to other fuels. Oxygen enrichment or replacement of air also enhances chemical and biological process efficiency.

Applications using oxygen include combustion, oxidation, fermentation, wastewater treatment and aquaculture. Combined with acetylene (CH) or other fuel gases or with argon (Ar) and carbon dioxide (CO₂), oxygen is also used for metal cutting, welding, scarfing, hardening, cleaning, and melting applications. In the food industry, oxygen is used to maintain a fresh, natural color, for example for fresh meat.

Air Products offers liquid oxygen and compressed oxygen gas in a variety of purities and in various modes of supply around the world thanks to our network of storage and transfill facilities.

Integra® Oxygen Cylinder and Flashback Arrestor


  • Built in flashback arrestor
  • Reduced exposure to pressure hazard, built-in regulator controls pressure and cannot be removed
  • Reduced risk of regulator damage, regulator fully contained within protective guard
  • Shorter and more stable cylinder has reduced risk of falling

Easier to use:

  • Smaller, lighter and more manoeuvrable than traditional cylinder
  • Snap-on connectors (no need for spanners)
  • Hand-operated on/off valve (no need for bottle keys)
  • Pre-set flow eliminates set-up time

More efficient

  • Never buy, repair or calibrate a regulator again

シリンダーの輸送? 安全な運転と安全な到着


  • 喫煙禁止
  • シリンダーバルブが適切に閉じていること、バルブキャップが取り付けられていることを確認してください
  • 車を換気する
  • レギュレーター、ホース、トーチなどを外します。
  • シリンダーが動かないように適切に固定する
  • 目的地へ直行
  • ボンベをブーツ内や換気の悪い場所に放置しないでください。
  • 目的地ですぐに荷降ろし、または長時間停車する場合は、換気のよい場所に保管してください。
