Single cylinders and cylinder packs are by far the most common. The main advantage of using a cylinder is that it can be moved around the workshop relatively easily.
Cylinder packs are ideal for those who need large volumes of gas for one-off jobs. Packs are also very popular because they provide a practical storage solution to cope with intermittent large requirements.
Compressed Gas Cylinders are most ideal where high pressure cutting is required. They are also most common mode of supply where Gas Mixtures and rare gases are required.
