In July I purchased a sign business. The previous owner was a packrat and among lots of other junk I found these three items pictured below. I have no idea what they are and can't find any info about them. Two of the items are identical. They have stainless frames. There is an electric motor in the middle and a "turbine" on each end. They have a gauge in the middle of the front panels and a few controls. The third item has an aluminum frame, motor, and turbines It has no switches or gauges. I can find the gauges on ebay(not worth much) but I can find anything that resembles the whole thing. Anybody have any idea what they are? Are they worth anything?
