Pneumatic Slip Ring
 

We are researching design ideas and are looking for a way to transfer compressed air over a rotating shaft. We don't want to use an actual slip ring for cost reasons and due to the fact we might have to already have a slip ring for the electronic connections.

What do you guys recommend?

I would recommend simplifying your design.

Can you mount at the center of the pivot axis? If so then a common air tool swivel will do the trick.

Most places that sell air tools will have a version.
