With its rotational forming process voestalpine Rotec GmbH & Co. KG has developed an aluminium pressure vessel which is manufactured out of seamless tubes. Pressure tests therefore can strongly be mimimised.

As for the production no welding or joining techniques are required, the pressure vessel can be produced with best applied costs.

The storage space at a diameter of 200mm can be varied by length adaptation up to 30 litres. Due to these options in storage space and a very low weight the vessel can be applied in various fields as air suspension in passenger cars or commercial vehicles.
