What is a centrifugal air compressor and how does it work?

Apr 9, 2025

Centrifugal air compressors are one of the most popular equipment in the construction and manufacturing industries, and have made great contributions to manufacturers and industries in terms of conveying and compressing gases in the best possible way. This article will introduce the concept, working principle, and more of centrifugal air compressors.

Introduction to Centrifugal Air Compressors

Centrifugal air compressors are a dynamic compressor that uses a rotating propeller to increase the pressure of the gas. The energy of the turbine impeller is the main source of power. The pressure of the gas is generated by its potential energy. They are ideal for industrial applications that require high gas flow, such as chemical production and power generation.

Main Features of Centrifugal Air Compressors

Power Range: Our centrifugal air compressors range from 15KW to 450KW, and are available in a variety of options to ensure that a variety of industrial tasks can find the right match. Our products range from small compressors for light work to large compressors that power heavy equipment.

Pressure Capacity: These compressors have an operating pressure range of 0.4Mpa to 1.0Mpa, allowing you to accurately match the pressure level required for your process.

Flow capacity: Our centrifugal air compressors have a flow range of 8m³/min to 484m³/min, which not only covers a wide range of gas volumes, but also technically does not have any related failures or inefficiencies.

Customization options: Shandong Sparta Machinery understands that each business has its specific needs and strives to provide different solutions. The compressors we distribute have customizable configurations and parameters so that customers can choose the machine they need. In addition, we can also assist customers with OEM/ODM production to meet the different needs of customers.

How does a centrifugal air compressor work?

The working principle of a centrifugal air compressor mainly includes the following steps:

1. Retraction: The air retraction device sucks in the adjacent air. The intake system is specially designed to allow the gas to pass through the machine smoothly and unimpeded.

2. Impeller rotation: The impeller of the compressor is actually the driving force of the compressor, and it rotates rapidly. It absorbs the kinetic energy of the gas and then ejects the gas outward by accelerating it. The problem with this mechanical component is that the rotational force can be dangerous.

3. Inertial force: The speed of rotation of the propeller is proportional to the energy generated by the gas, so the gas is pushed faster. This results in a significant increase in the gas speed.

4. Diffusion behind the impeller: The gas from the impeller loses kinetic energy rapidly as it flows through the diffuser and expansion channel. As the gas is slowed down, the pressure in this area rises.

5. The gas is compressed: The compressed gas is transported or processed. Each individual process is carried out in series, and the result is a continuous and high-quality compressed air flow.

What are the advantages of centrifugal air compressors in industry?

Efficiency: Centrifugal air compressors are able to produce high-flow energy without consuming a lot of central grid electricity. They are designed for stable operation and are therefore suitable for large-scale production.

Durability: Compared with other types of compressors, they require less manpower for regular cleaning, so the operating costs are also lower.

Versatility: Centrifugal gas compressors are not only indispensable in gas processing, but also in the chemical, petrochemical and equipment manufacturing industries as a main tool for converting raw materials into final products.

Scalability: As your business grows, you can quickly and economically expand the capacity of the compressor without changing the infrastructure configuration.

Overall, the machine is excellent because it is very flexible and can respond quickly to market changes with minimal cost and time.
