The Piston air compressor is another positive displacement compressor. These air compressors are usually found in smaller work sites such as garages and home building projects. Unlike screw compressors, piston compressors are not designed for continuous use. Piston air compressors have more moving parts compared to screw compressors. These parts need to be lubricated with oil for smoother movement. This type of air compressor works through a piston in the cylinder, which compresses and moves air to generate pressure. There are piston compressors that work single-stage or two-stage, depending on the air pressure generated. When you need more power, a two-stage compressor can be the right choice. The single-stage compressor is suitable for getting work done for smaller projects such as woodworking and metalworking.

Aside from that, a two-stage compressor delivers the power required for intense construction, such as assembly and auto maintenance. Multi-stage reciprocating compressors can reach up to 30HP.

On the other hand, there’s also the Axial air compressors. They are not normally used in construction projects but are instead found in high-speed engines on ships or aircraft. They have a high level of efficiency but are considerably more expensive than other types of air compressors, and can run into thousands of horsepower, which is why they are mainly reserved for aerospace research.

Then, perhaps you also need to know about the centrifugal air compressor. A centrifugal air compressor slows and cools the air entering through the diffuser to build up potential energy. Due to the multi-phase compression process, centrifugal compressors can generate large amounts of energy in relatively small machines.

They require less maintenance than screw compressors or piston compressors. Several types of centrifugal compressors can produce oil-free air.

They are usually used for more demanding construction sites such as chemical plants or steel manufacturing centers, as they can reach around 1,000 horsepower.
