How Do Air Compressors Work?

Air compressors function by forcing pressurized air into a container. The air then compels through the opening of the tank where the pressure builds up.

For example, take a gallon and fill it with air, then open it. You would notice that air will rush out with force.

When the balloon is opened, the compressed air released can be used as energy. These air compressors are powered by a motor that converts electrical energy or power into kinetic energy.

They work similarly to a combustion engine that uses a piston, valve, connecting rod, head, and crankshaft.

When the tank is filled with pressured air to its full capacity, the motor will be shut, and the pressured air will be reserved in the tank until it is used.

The ability of air compressors to store air with its tank makes it different from a pump. Compressed air in the tank can also power a wide range of tools such as sanders, impact wrenches, nailers, and paint sprayers.

After the air stored in the tank has been released, the container will be decompressed. Then from the lowest limit of the container, the compressor re-pressurizes, and resumes, generating potential energy within the tank, thereby fill it with air.

Types of Compressors

Types of Compressors

There are numerous types of compressors out there, and they can be categorized in a myriad of different ways. In this article, we will categorize air compressors in terms of pressure, designs, and functionality.In terms of pressure, there are three major types of compressors.
