The best industrial air compressors for light manufacturing

Written by Jeremy Richards | Mar 14, 2025 1:45:51 AM

Are you using the right air compressor and tools in your factory or plant? Air compressors are a must-have tool for manufacturing, making tasks and assembly lines move quickly, easily, and affordably.

In this article, we outline the most common applications for an air compressor in a factory, light manufacturing facility, or packaging plant. We also explain how to choose the right air compressor for your needs, including the best option for various manufacturing scenarios. 

Common Applications of Air Compressors in Manufacturing

Air compressors are used in light manufacturing for a variety of tasks. 

Powering pneumatic air tools

Compressed air is critical in running a variety of pneumatic tools to streamline assembly lines and boost efficiency. Tools that use an air compressor include drills, grinders, nail guns, staplers, and sanders. 

Material handling and packaging

Compressed air is also used to power automated systems such as conveyor belts, robotic arms, and pneumatic packaging machines.

Spray painting and product coatings

Air compressors provide a steady flow of air for paint sprayers and coating systems, ensuring a smooth, even finish.

Cleaning

Using compressed air, you can easily remove dust, debris, and moisture from products, work surfaces, and machinery. A popular example of this is using an air compressor vacuum or air blower to clean your workspaces. 

Moulding and forming

Compressed air is commonly used for supporting processes like injection moulding, thermoforming, or air-powered stamping.

Cooling and drying

Compressed air can be used to cool hot or dry materials during production, helping to maintain product quality. 

 

 

How to Choose the Right Air Compressor

Choosing the right air compressor for your needs depends on air pressure (PSI), air volume (CFM), tank size, and air purity requirements. 

Air pressure (PSI)

You need to choose an air compressor that can match the end-use tool with the highest PSI rating. If your tools require different pressure levels, use pressure regulators to manage them.

CFM requirements

Cubic Feet per Minute, or CFM, is the volume of air your air compressor can supply. To calculate yours, add up the peak air consumption of all your end-use tools, remembering to account for any tools operating simultaneously. 

Tank capacity 

An air receiver tank stores compressed air between the compressor and the end-use tool. This reduces how often the compressor needs to run. Your tank size (in gallons) should be roughly one-quarter to one-third of the CFM output. 

Air purity

In manufacturing and packaging, you may need a high level of air purity (class 0). An oil-free air compressor offers the highest air quality, with no oil to contaminate the air. This means you don’t need as much filtration.

Best air compressor for air tools

Variable-speed air compressors deliver reliable performance for many light manufacturing applications. With a direct-coupled design, these compressors ensure consistent airflow while dynamically adjusting speed to match demand. This is especially valuable in environments where production equipment operates at varying loads, helping to optimise energy use and reduce wear.

We recommend PneuTech’s RSCR series of direct-drive variable-speed compressors. They’re engineered for efficiency and durability, incorporating advanced technology to meet the demands of modern manufacturing.

Best all-rounder air compressor for light manufacturing

Rotary screw air compressors are an excellent choice for light manufacturing, providing a steady airflow and consistent pressure to support multiple machines and tools simultaneously. 

For precision applications like paint spraying or product finishing, an oil-free rotary screw compressor will ensure clean, contaminant-free air. Alternatively, you can also incorporate dryers and filtration systems to clean air.

Product recommendation — Vixen Integrated Air Compressors

The Vixen Integrated Air Compressors are an excellent choice for manufacturing applications. These compressors feature: 

  • A highly efficient permanent magnet motor
  • An energy-saving dual cooling system
  • A direct connection without gearing. 

Altogether, these features ensure significant energy savings and reduced maintenance.
