Air compressors are widely used in almost all industries. They provide the energy for hand tools, machines and robotic tools. Using compressed air is just as common as using gas and electricity! It is therefore important to select the air compressor type that suits your needs. This article examines the most popular types of air compressors. Piston or reciprocating compressors use pistons to compress air and then store them in a high-pressure tank. Then the air is released by pressing the actuated valve. Piston / Reciprocating compressors are most often used for personal, domestic and light industrial jobs. The reason for this is that there is a wide range of portable models available, and these are often have the most reasonable prices. The next type of compressor is a rotary screw that uses double screws instead of pistons to make high pressure air. Since they have higher operating range than piston compressors, they are often used in ordinary industrial work. Both recipro
