Beverley Chase Air Compressor August 10th, 2018 - 05:44:38
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.
A portable air compressor comes in many shapes and sizes. We are only truly portable if we don't get too big. As long as we can be moved around easily and used where needed then we are considered truly portable. Once we get too big, then we are relegated to shop work and other stationary jobs. I pity these poor fools. It would be boring to just sit in one shop all day. I like getting out and seeing different places and meeting different people. I think it keeps me young.
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.
So air compressor manufacturer will find ways to create breakthroughs to be able to meet industries changing needs. But the most important thing you need to look into is safety.
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.
Most industries prefer the industrial air compressor for their convenience. But even home owners could keep an air compressor pump around, for their needs. There are a variety of portable air compressors available.
