What size of (industrial) air compressor do I need?

Industrial air compressors are essential tools in various industries, from construction to manufacturing. Selecting the right size of an industrial air compressor is crucial for ensuring optimal performance and efficiency.

The same applies for the type of compressor, like an oil-lubricated or oil-free one. If you need a constant airflow, the size will matter as well: smaller air compressors are usually not fitted to generate a constant flow. 

This comprehensive guide will delve into the factors that determine the size of an industrial air compressor, the types of air compressor, and how to choose the right one for your needs.

Factors Determining the Size of an Industrial Air Compressor

Nature of Work and Types of Tools

Size of air compressor: air tools

The size of an industrial air compressor largely depends on the nature of your work and the types of tools you use. For instance, heavy construction work may require a larger compressor compared to tasks around the house.

The tools you use will have specific air requirements, which will influence the size of the compressor you need. Always consider what size compressor for air tools your projects require.

Required Airflow or CFM

Air tools have a required airflow or CFM (cubic feet per minute) requirement, which determines the minimum airflow your compressor should generate. The CFM requirement is usually specified by the tool manufacturer and is a critical factor in selecting the right compressor size. When asking what size compressor for air tools, you should always consider the CFM requirements specified by the tools' manufacturers to ensure optimal performance.

Voltage and Portability

The compressor's voltage and portability are also essential factors to consider. Depending on your work environment, you may need a compressor that can be easily moved around or one that operates on a specific voltage.

Tank Size

Size of air compressor: tank size

Compressor tank sizes vary, and selecting the right size helps determine how long the compressor will run before requiring a refill. A larger tank can store more air, reducing the frequency of refills and ensuring a steady supply of compressed air.

This consideration is especially relevant when deciding what size air compressor for air tools will best suit your needs.

Constant Airflow Requirements

If you need to operate tools that require constant airflow, you'll need a large tank to avoid frequent motor switching, which can compromise the compressor's lifespan.

Types of Industrial Air Compressors

  • Rotary Screw Compressors: These compressors use two rotating screws to compress air. They are ideal for continuous operation and are commonly used in industrial applications.

  • Reciprocating Compressors: These compressors use a piston to compress air. They are suitable for intermittent use and are commonly found in smaller applications.

Understanding CFM Requirements for Air Tools

When it comes to air compressors for air tools, size does not determine the compressor's power. Instead, operators should assess the tools' air requirements and find an air compressor that meets those requirements.

Air compressors come in various sizes, and bigger is not always better. Large-looking air compressors may have low air output, while compact air compressors could produce high air output.

Operators should assess an air compressor's capability by how much air it delivers in CFM instead of physical size. Most air compressors fall in the 10 to 110 CFM range for powering tools. Lower CFM air compressors work well for small tools, while higher CFM air compressors are designed for industrial applications and bigger tools.

When determining what size air compressor for air tools is best, it is recommended that you match the compressor's CFM rating with the requirements of your tools to ensure optimal performance.

Importance of Voltage and Portability

The voltage and portability of an air compressor are crucial factors to consider, especially if you need to move the compressor around frequently or if you have specific voltage requirements. Portable compressors are ideal for job sites where mobility is essential, while stationary compressors are better suited for fixed installations.
