Frequently asked questions about oxygen cylinders

Which cylinder size is suitable for which application?

Compact cylinders from 0.3 to 1 litre are particularly suitable for mobile emergency equipment. 2- and 3-litre cylinders offer a good compromise between mobility and reserve. 5- and 10-litre cylinders provide larger reserves; 50-litre cylinders are intended for appropriately planned stationary applications.

How is the gas reserve of an oxygen cylinder calculated?

The theoretical gas reserve is derived from cylinder volume and filling pressure. A 2-litre cylinder at 200 bar contains around 400 litres of oxygen, for example, while a 10-litre cylinder contains around 2,000 litres. Actual operating time depends on the selected flow and operating conditions.

Which pressure regulator is compatible with the oxygen cylinder?

Conventional oxygen cylinders require a suitable pressure regulator. Connection, inlet pressure, flow range, tubing and patient interface must be technically compatible. In suitable combination-valve systems, pressure reduction is integrated into the valve unit.

What should I consider about the use-by date and technical inspection interval?

Medical oxygen is a medicinal product. The use-by date shown on the cylinder is authoritative; for our fillings, the use-by period is generally 35 months from filling. The compressed-gas cylinder itself is also subject to separate technical inspection intervals. These two periods must be considered separately.

Should I buy or exchange an oxygen cylinder?

For new equipment, purchasing a suitable cylinder is the direct starting point. For suitable existing cylinders, our exchange service is available. Complete solutions are available under emergency systems with medical oxygen.
