L7X® – aluminium type 1 cylinders

Our L7X all-metal oxygen cylinders are manufactured from Luxfer’s higher-strength L7X aluminium alloy. L7X advantages include higher-pressure filling up to 300bar and significantly more gas capacity with no increase in cylinder size or noticeable weight gain.

We work closely with healthcare institutions and authorities to give us real insight into the needs of their patients. Each of our cylinders is designed to give people with respiratory conditions greater freedom and a better quality of life.
