Types of Air Compressors


When it comes to powering various tools and equipment, air compressors play a crucial role. From construction sites to manufacturing plants, air compressors are indispensable in a wide range of industries. However, with numerous types of air compressors available in the market, it can be challenging to determine which one suits your specific needs, air compressors are used for multi-purpose use such as paint spray gun, inflating tires, and more. In this comprehensive guide, we will explore the different types of air compressors, their unique features, and the applications they excel in. So, let’s dive in and discover the world of air compressors!

What are the Types of Air Compressors?


Reciprocating Air Compressors

Reciprocating air compressors, also known as piston compressors, are one of the most common types of air compressors used today. These compressors work on the principle of positive displacement, where the reciprocating motion of pistons compresses the air within a cylinder. They are available in both single-stage and two-stage configurations, with the latter providing higher pressures. Reciprocating compressors are suitable for small to medium-sized applications and find extensive use in workshops, automotive repair, and pneumatic tools.

Rotary Screw Air Compressors

Rotary screw air compressors are known for their reliability and efficiency in delivering a continuous supply of compressed air. Unlike reciprocating compressors, rotary screw compressors utilize two interlocking helical screws to compress the air. This design ensures smooth operation, reduced vibrations, and minimal maintenance requirements. These compressors are ideal for large-scale applications such as manufacturing plants, construction sites, and industrial processes that require a steady flow of compressed air.

Centrifugal Air Compressors

Centrifugal air compressors are widely used in industries where high volumes of compressed air are required. They operate based on dynamic compression, where the kinetic energy of the rotating impeller is converted into pressure energy. Centrifugal compressors are capable of delivering large volumes of compressed air at high pressures, making them suitable for demanding applications such as power generation, chemical plants, and refineries. They are known for their energy efficiency and can handle continuous operations with minimal maintenance.

Axial Air Compressors

Axial air compressors are primarily used in specialized applications that require high flow rates but relatively low pressures. These compressors feature a series of rotating blades that accelerate the air in an axial direction, resulting in increased airflow. Axial compressors are commonly found in HVAC systems, ventilation systems, and large-scale cooling applications. They are known for their compact design, lightweight construction, and ability to handle high volumes of air efficiently.

Diaphragm Air Compressors

Diaphragm air compressors operate using a flexible diaphragm that moves back and forth to compress the air. These compressors are widely used in applications where oil-free and contaminant-free air is crucial, such as the pharmaceutical and food industries. They are also commonly employed in portable devices, airbrushing, and medical equipment. Diaphragm compressors offer exceptional reliability and can deliver consistent air pressure even at low flow rates.


Having a clear understanding of the different types of air compressors is essential for choosing the right one for your specific application. Each type of compressor has its unique features and excels in different environments and industries.

Reciprocating air compressors are reliable and suitable for small to medium-sized applications, while rotary screw compressors provide a continuous supply of compressed air for larger-scale operations.
