Are you looking for the best air compressor for painting cars? An air compressor is a critical piece of equipment for any auto body shop, as it powers the spray gun for painting vehicles. If the air compressor fails, it becomes impossible to complete a paint job without purchasing a replacement. However, not all air compressors are suitable for use with spray guns. It’s important to consider several key factors carefully when selecting the right air compressor for auto painting applications.

How to find the best air compressor for painting cars?
Best air compressor for painting cars
When selecting an air compressor for auto painting applications, there are several key factors to consider to choose the best model. The most important specifications are the air volume (measured in cubic feet per minute or CFM) and the air pressure (measured in pounds per square inch or PSI).
For typical spray gun requirements in automotive painting, an air compressor should provide at least 5-7 CFM of airflow at 90 PSI. This level of performance will ensure the spray gun has sufficient air power to atomize the paint properly and deliver a high-quality finish.
Some top air compressor recommendations for car painting include:
- Ingersoll Rand 2340L5-V 80-Gallon Single-Stage Air Compressor – Provides 17 CFM at 90 PSI, making it well-suited for multiple spray guns.
- California Air Tools 10020C Ultra Quiet Oil-Free Air Compressor – Delivers 6.4 CFM at 90 PSI in a compact, low-noise design.
- DeWalt DXCMPA1982054 20-Gallon Portable Air Compressor – Offers 5.7 CFM at 90 PSI in a portable, wheeled unit.
- Craftsman HARD 10 Gallon Oil-Free Air Compressor: Powerful, with a large tank capacity and low noise level.
- Stealth SAQ-11215: Another runner-up with excellent performance.
- DEWALT DXCM271.COM: Lightweight, powerful, and suitable for longer projects
The tank size is also an important consideration, with larger 20-80 gallon tanks providing more reserve air capacity between compression cycles. Prioritizing the right CFM and PSI specifications will ensure the air compressor can reliably power spray guns for high-quality automotive painting.
What size air compressor to paint cars?
When selecting an air compressor for auto painting applications, the size and performance specifications are critical factors to consider. The most important metrics are the air volume (measured in cubic feet per minute or CFM) and the air pressure (measured in pounds per square inch or PSI).
For typical spray gun requirements in automotive painting, an air compressor should ideally provide at least 5-7 CFM of airflow at 90 PSI. This level of performance will ensure the spray gun has sufficient air power to atomize the paint properly and deliver a high-quality finish without issues like orange peel or excessive overspray.
In terms of compressor size, a good starting point for auto painting is a 20-30 gallon tank. This tank size provides enough reserve air capacity to maintain consistent pressure and airflow through the spray gun, even during extended painting sessions. Larger 50-80 gallon tanks can provide even more air volume for greater productivity but may be overkill for most body shop needs.
Some recommended air compressor sizes and specifications for auto painting include:
- 20-30 gallon tank, 5-7 CFM at 90 PSI
- 50 gallon tank, 7-10 CFM at 90 PSI
- 80 gallon tank, 10-15 CFM at 90 PSI
Choosing the right compressor size and performance level is essential to ensure optimum spray gun operation and a high-quality paint finish. Prioritizing the appropriate CFM and PSI specifications will help body shops select the best air compressor for their automotive painting requirements.
What is the Best Air Compressor for Painting Cars?
When it comes to selecting the best air compressor for automotive painting, the most critical specifications are the air volume (CFM) and pressure (PSI) the compressor can deliver. For typical spray gun requirements in car painting, you’ll want an air compressor that can provide at least 5-7 CFM at 90 PSI. This level of airflow and pressure is necessary to properly atomize and apply the paint without issues like orange peel or excessive overspray.
The motor horsepower and power source (electric or gas) should be sufficient to reliably generate the required CFM and PSI. More powerful 5-7.5 HP compressors are generally better suited for demanding auto-painting applications.
If mobility is a priority, consider a portable air compressor with wheels and a handle for easy transport around the body shop.
Look for models with low noise levels, around 70-80 dB, to minimize disruption in the work environment.
By selecting the best air compressor for painting cars that meet the specific airflow, pressure, and other requirements for automotive painting, body shops can ensure optimal spray gun performance and a high-quality paint finish every time.
Painting Spray Compressor

A 30-gallon spray paint with compressor may be suitable for smaller spray painting jobs like furniture, but it would struggle to keep up with the airflow demands of painting an entire car body in one continuous session. The limited air reserve in a 30-gallon tank would likely lead to frequent compressor cycling and pressure drops, negatively impacting the paint atomization and finish quality.
For car painting projects, you are right that a larger compressor, in the 60-80 gallon range, would be a much better match. The increased air volume and reserve capacity of a larger tank would allow the compressor to maintain the necessary 5-7 CFM at 90 PSI that spray guns require, without interruptions. This would enable painters to work more efficiently and achieve a consistently smooth, professional-grade paint finish across the entire vehicle.
Makita MAC700 Gallon Air Compressor
The Makita MAC700 (best air compressor for painting cars) is an excellent example of a relatively small air compressor that punches above its weight in terms of performance and features. Despite its compact 2.6-gallon tank, this compressor has some impressive capabilities that make it well-suited for certain spray painting applications.

The highlights:
- Fast Refill Time: The Makita MAC700 can fill its 2.6-gallon tank in less than 2 minutes, thanks to its efficient single-cylinder pump design with a larger bore, piston, and stroke length. This quick recharge time can be a major advantage for smaller painting jobs or touch-ups where you don’t need extended continuous runtime between refills.
- Quiet Operation: Being an oil-lubricated compressor, the MAC700 runs very quietly, around 80 dB. This low noise level is ideal for working in confined spaces or noise-sensitive environments, like residential garages or workshops.
- Easy Maintenance: The accessible oil sight glass and drain valve make it simple to check the oil level and change it out as needed, ensuring optimal performance and longevity of the compressor.
