This kind is suitable for people on the go or who travel. You never have to go through the tedious task of having to find a vehicle big enough to carry your compressor wherever you wanted to go.
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.
A rotary screw compressor uses screws to force the gas into a smaller space. These can be quite compact or larger for industrial uses. The tighter the threads on the screws, the greater the compression. This type of compressor does tend to run a bit smoother and with less vibration than other types.
