A Complete Guide to 4 Industrial Air Compressor Types

As a professional supplier, BOAO Air Compressor Co., Ltd understands that selecting the right air compressor is crucial for operational efficiency and cost control. Industrial facilities require a variety of compressed air systems, ranging from small workshops to large factories, with vastly different performance requirements. In this article, we will explain the main air compressor types from a technical perspective and highlight BOAO’s solutions to help you make the right choice.

Compression Technology: Dynamic vs Positive-Displacement

Industrial air compressor typs are broadly divided into two categories: positive-displacement compressors and dynamic compressors.

• Positive-displacement compressors trap a fixed volume of air mechanically and reduce the volume to increase pressure.
• Dynamic compressors impart high velocity to the air using fast-rotating components, converting kinetic energy into pressure.

Each type of compression principle is suitable for different industrial applications.

Main Compressor Types and Features

Dynamic Compressors

Centrifugal Compressor

Centrifugal compressors accelerate air with a high-speed impeller, converting velocity into pressure.

• Advantages：Suitable for high flow rates and continuous operation, often providing oil-free air.
• Applications： Large industrial plants, high-capacity systems.

Axial Compressor

Axial compressors compress air along the shaft using rows of stationary and rotating blades.

• Advantages：Extremely high airflow capacity.
• Applications：Systems requiring very high flow rates.

Positive-Displacement Compressors

Reciprocating / Piston Compressor

Reciprocating compressors use pistons moving back and forth to compress and discharge air.

• Advantages：Simple construction, easy maintenance, suitable for intermittent use.
• Applications：Small workshops, service shops, intermittent applications.

Rotary Screw Compressor

Rotary screw compressors use two intermeshing helical rotors to compress air continuously.

• Advantages：Continuous and stable output, energy-efficient, long service life.
• Applications：Large production lines, continuous industrial use.

Differences between the air compressor types

Understanding the differences between air compressor types is key to choosing the right one for your needs. Let’s explore these differences at a glance.

Aspects	Rotary Screw Compressors	Reciprocating Air Compressors	Axial Compressors	Centrifugal Compressors
Compression Method	Uses two rotating screws.	Uses pistons within a cylinder.	Rotating blades compress air.	Impeller spins to increase pressure.
Airflow	Continuous and steady.	Short bursts of high pressure.	High-speed, large-volume flow.	Continuous for extended operations.
Best Use	All industrial segments and commercial settings.	Workshops and small businesses.	Aviation and energy sectors.	Factories and cooling systems.
Portability	Compact and portable.	Lightweight and portable.	Not portable due to size.	Compact but stationary.
Maintenance	Low, due to fewer moving parts.	High, with frequent servicing.	Complex and costly maintenance.	Low, with simple design.
