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.
I found a nice air powered air gun at a local hardware store. At first it seemed just perfect. I was about to buy it when I noticed on the little description card that it was not recommended to be used with a compressor smaller than 6 gallons. Dang! The portable air compressor I had was only a small 2 gallon pancake compressor. That just wouldn't cut it. I had to buy a larger unit so that I could get the gun, so that I could finish the house project. See how this goes.
With nearly 40 online reviews from actual customers, the VIAIR 90P Portable Compressor has an above average customer score of 4.5 out of 5 stars. No, it’s not a heavy duty compressor to use in the garage or on carpentry projects, but the VIAIR 90P Portable Compressor is a great tool to have on hand to inflate tires or possibly pool floats and sports balls. It does the job quickly, and is a nice tool to have in the trunk of your car for those little emergencies that pop up when you need quick air in your tires.
