The energy created from the motion of the blades builds up air pressure in a shorter amount of time. Next, it is moved into a storage tank and saved for later use.ĭynamic displacement: Also called nonpositive displacement, this method uses an impeller with rotating blades to bring air into the chamber. There, the machine reduces the volume of the chamber to compress the air. Positive displacement: Most air compressors use this method, in which air is pulled into a chamber. There are two primary types of air displacement used for this purpose: To compress air, the internal mechanisms within the compressor move to push air through the chamber. What Is Air Displacement?Īir displacement is at the core of each air compressor.

The compressor will turn back on when the pressure drops below a specific number.Īir compressors don’t need to have storage tanks, and a few of the smaller options forego them in favor of portability. Once the storage tank reaches its maximum air pressure, the compressor turns off. The vacuum pushes the air out of the chamber and into its storage tank. The compressor draws in air and creates a vacuum to reduce its volume. An inlet and a discharge valve to draw in and release air.Most compressors use reciprocating piston technology. So, how does an air compressor get air? For those that use pistons, it involves two parts: Raising the pressure and reducing the volume of the air. They are also long-lasting, require less maintenance and are easier to move than other old-fashioned machinery. The compressors themselves are more compact and lightweight than other centralized power sources. Generally, air compressor operation requires a pump cylinder, piston and crankshaft to transfer energy for a wide variety of tasks. These basic components can help supply air for filling up objects like tires or inflatable pool toys, or they can supply power for operating tools such as drills, nail guns, grinders, sanders and spray guns.įrom impact wrenches to AC units, many versatile air-powered tools and machines are responsible for the comfort, shelter, automation and efficiency of everyday life. Industrial air compressors work similarly to combustion engines.

Just like an open balloon, the pressure builds up when the compressed air is deliberately released, converting the potential energy into usable kinetic energy. From there, this energy transfer can be harnessed to power various pneumatic tools. Air compressors work by forcing atmospheric air under pressure to create potential energy that can be stored in a tank for later use.
