Terms of the Trade: What Is an Air Compressor?

Lead Image

Air compressors are handy devices for avid DIYers to have in their workshop because they can supply energy to pneumatic power tools, which are usually faster, lighter, and have more power than traditional power tools. Air compressors are usually powered by gasoline or electricity, converting that power into energy stored in pressurized air. Air compressors come in either stationary or portable models, with different sized tanks depending on the DIYers needs. The smaller the tank, the less time it can be used before the compressor turns back on.
