The most common is the piston compressor. This falls under the positive displacement compressors, which you can find in fractional to very high horsepower ranges. The positive displacement air compressor works by filling an air chamber with air and reducing the chamber volume.
Needing to fill up a tire with air, while you’re out and about can be a real challenge. If you’re tired of being stuck with deflated tires on the road, you have probably considered ordering a portable air compressor. One of the problems with these types of compressors is the fact that many of them use a car lighter plug to deliver power to the compressor.
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.
You will need at least one regulator and a water trap in line before the regulator. These are not costly. A regulator allows you to set the correct air pressure for the tool you will be using (say, 80 PSI) instead of tank pressure (say, 175 PSI).
You cab always rely on the air compressor pump to address your needs. High pressure air is a precious resource, especially in industries because it is safe, convenient, clean and flexible. Industries have been relying in it for over a century.
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.
