How to Increase CFM on Air Compressor

Are you tired of working with an air compressor that does not produce enough power? Does it take longer than necessary to complete tasks like painting, sanding or grinding? The culprit may be a low CFM rating of your air compressor. CFM simply stands for Cubic Feet per Minute and it determines the volume of air that the compressor can deliver.

The lower the CFM rating, the less powerful the air compressor. But have no fear, there are ways you can increase the CFM on your air compressor

1. Increase the Size of Your Air Compressor Tank

One way to increase CFM is to increase the size of the air compressor tank. A larger tank allows you to store more compressed air which means that the compressor does not have to turn on as often. This results in a higher CFM rating and increased power. However, keep in mind that if you plan on using your compressor for long periods of time, you may want a larger motor to keep up with the demand.

2. Replace Your Air Compressor Pump

Another way to increase CFM is to replace the air compressor pump with one that has a higher CFM rating. Different pumps have different capacities, and a pump with a larger capacity can deliver more air with each stroke. An air compressor pump can be a significant investment, but it is an investment that can quickly pay for itself with increased productivity.

3. Use Larger Hoses

Hoses are a critical part of your air compressor system, and choosing the right size can improve your overall CFM rating. A larger diameter hose will reduce air resistance and allow more air to flow through. When possible, use a hose with a 3/8 inch diameter or larger.

4. Clean or Replace Air Filters

Over time, air filters on your air compressor can become clogged with dust and debris. A clogged air filter can reduce the amount of air flowing through your compressor, which in turn lowers your CFM rating. Check and clean your air filters regularly, and replace them when necessary, to maintain maximum air flow.

5. Use an Air Regulator

An air regulator is a device that allows you to adjust the air pressure coming out of your compressor. By regulating the pressure, you can adjust the CFM rating of your compressor. Lowering the pressure will increase CFM, while raising the pressure will decrease CFM. This adjustment will help you deliver the right amount of air required by different tools and tasks.


By following these five effective ways to increase the CFM rating of your air compressor, you can enhance the overall performance of your air-powered tools and complete tasks faster and more efficiently.

Additionally, these measures can reduce wear and tear on your compressor, saving you money on repairs and replacements. Don’t put it off any longer, give these methods a try and take your air compressor to the next level!
