A rotary vane air compressor uses a rotor and a number of blades in radial slots in the rotor. I do not fully understand how this works, but it has something to do with the rotor turning and the blades sliding in and out of their slots as they keep contact with the housing wall. This somehow creates decreasing volume.
Years later, I built a smaller woodworking shop in my home which only required one air sander running at a time. For that shop, I purchased an air compressor half the size and isolated it in a soundproof room in one section of the shop. I ran galvanized pipe under the shop floor to three regulators at three different connection locations. The machine I purchased for that shop as a 5 HP Ingersoll Rand model with an 80 gallon tank. At the 80 PSI required by my Dynabrade sander, the compressor would produce enough air from morning to night. I must say that that compressor was very well built. All I had to do was keep an eye on the oil level in the sight glass. At night, I would turn off the master air valve on the side of the air compressor, leaving the electricity on, to silence the compressor until the next work day.
I happen to be just a small portable air compressor. I live with a nice man named John who owns a small construction business. He takes me with him wherever he goes. Usually, we visit job sites where John goes up to other men and talks to them about important stuff. I just hang out in the truck waiting patiently. Sometimes, John will come back to the truck and take me out to start working. These are the good days. Other times, we have to drive off and come back another day.
