Centrifugal compressors use rotating vanes to compress gas, making them more energy-efficient and durable than piston compressors. They are used in high-end air compressors, refrigeration units, and air conditioners, as well as in turbochargers and small aircraft engines. They provide a constant supply of air for air tools and machines in manufacturing and automotive refinishing operations. Their smooth discharge of air ensures optimal group results.

A centrifugal compressor is a type of compressor that uses rotating vanes or impellers to compress a gas instead of a piston. This design is used in high-end air compressors as well as on refrigeration units and air conditioners. This type of compressor can be used in stages to create ultra-high compression of gas or air. This type of compressor has fewer moving parts and runs more smoothly than a piston compressor.

Turbochargers use a centrifugal supercharger due in part to durability and the ability to operate at sustained high engine speeds or revolutions per minute (RPM). Compared to a positive displacement compressor, a centrifugal one is much more energy efficient. The only drawback is the need to perform multiple stages to achieve ultra-high compression. An advantage of this type of compressor is the ability to run for extended periods with little change in output level.

Quieter operation and lower cost of production make the centrifugal compressor a popular choice for small aircraft engines. Ease of maintenance and durability in extended operation suit this compressor for aircraft gas turbine engine applications. In manufacturing, this type of air compressor is preferred for producing a constant supply of air to drive air tools and air powered machines.

Primarily used for medium volume and pressure air operated pumps in manufacturing, the ability to provide a smooth discharge of air is beneficial to the operational readiness of an assembly line environment. By supplying large amounts of compressed air at constant pressure and volume, air tools used in an assembly line situation operate at the correct speed and deliver constant torque over a long period of time.

The centrifugal compressor is often the preferred type of air compressor for use in automotive refinishing operations. The constant flow and volume of air allows sanders and other tools to run continuously for hours. The fact that the oil is separated from the air by diaphragms and seals allows the tools to operate without contaminating the work surface with oily residues. This feature in a centrifugal compressor also benefits the paint process and eliminates the danger of getting oil into the paint system. From auto repair shops to automotive turbochargers and aircraft engines, the centrifugal pump provides adequate airflow and pressure to allow each individual use to achieve optimal group results.
