What is a two stage air compressor?

A two stage air compressor is a type of air compressor that compresses air by using two cylinders or stages. It consists of two pistons that work in two stages to compress the air, generating higher pressure than a single stage compressor.

In the first stage, the air is compressed to an intermediate pressure level and then passed on to the second stage, where it is compressed to a higher pressure level. The lower pressure achieved in the first stage allows for a more efficient compression process in the second stage. This results in a greater volume of air being delivered at a higher pressure.

Two stage air compressors are commonly used in industrial settings where high volume and pressure air is required for pneumatic tools, painting, sandblasting, and other similar applications. They are more expensive than single stage compressors but deliver better performance and efficiency in terms of higher output and lower energy consumption.
