This energy and pressure distributor is mobile and can supply several workstations. Up to now, the production system was quite inflexible. The distributor was mounted in a static position on the ceiling and had a limited radius of 2 metres. Now it has been attached to a drylin® W rail mounted overhead, and can easily be moved and used at several assembly work stations. The whole system is absolutely reliable and completely maintenance-free thanks to its lubricant-freedom.
