How can we save power?
The 2nd component was a rotary air compressor. In the video they show the tag on the side of it. Not knowing what a unit like this was used for, I stopped in at an electric motor repair shop, a heating and air conditioning center, an auto parts store and am appliance repair store. None of them had ever seen such an item and didn't know where to turn. I finally got on the internet and did a search for the manufacturer, which had been bought out by another company. After speaking with three different customer service and technical reps, I was able to speak with an engineer that told me that those units came from old stand alone respirators that use to be used in hospitals. That sort of equipment had not been manufactured in over 15 years. Today, hospital patients use the hospital oxygen system. Stand alone units don't have individual pumps, they are all built into the units and combined with other electronic components, etc.
