How to Choose the Right Air Compressor for Cars Painting?

If you want to make sure that you get the best air compressor for painting cars, you have to be careful. So, these are the things to consider when shopping:

  • PSI

When it comes to measuring the air pressure, the main thing you have to consider is its PSI. Stands for Pounds per Square Inch, PSI is used to measure an air compressor’s air pressure. But since most of the spray guns you can combine today with air compressors are HVLP (High Volume Low Pressure), they have low PSI.

Even if you if you replace your HVLP spray gun with LVLP (Low Volume Low Pressure) one, you still need an air compressor with low PSI output. This is where the CFM requirements come in since it’s where the difference between these 2 types of spray guns relies on.

  • CFM

The CFM or Cubic Feet per Minute rating of an air compressor pertains to how much air is delivered per minute. But since your aim is to use turn your paint into droplets with the spray gun, you have to make sure that its CFM rating is high enough. This is also because most spray guns are constantly used especially in auto body shops for painting. Normally, spray guns have 90 – 100 CFM ratings.

This means that the best air compressor for painting cars should be 4 – 19 CFM per unit when undercoating. Be careful when choosing the right CFM rating since too low CFM will cause the paint to spatter with the uneven flow.

  • Tank’s Size

If you want to finish your task in record time, be sure to have an air compressor with enough tank size. Not to mention the fact that you would be using your spray gun continuously for hours. Thus, your air compressor’s tank size should be at least 50 to 60 gallons.

How to Setup Your Air Compressor Kit with a Spray Gun?

Aside from picking the right air compressor, be sure to set up the following parts in correct order:

  • Filter

Remember that the air from the compressor should be clean and dry. The connections of the compressor should be tight enough to ensure that your spray gun will run smoothly. Using the right filter for the job will help you get rid of oil and moisture. The filter will also help you adjust the necessary air pressure.

  • Air Hose

This is located between the air compressor and the spray gun to allow a smooth airflow. If your hose is too long or too narrow, it may trigger the pressure drop. Take note that a hose with smaller ID or inside diameter means less air pressure it can provide. Thus, you need at least 5/16” think hose for High Volume Low-Pressure spray guns, and ¼” think hose for Low Volume Low-Pressure spray guns. The length of your hose should always match the ID to control its air limit.

  • Regulator

Depending on your job requirement and needs, the regulator could be gun-mounted or wall-mounted. Gun-mounted regulators are best only for personal and DIY projects while wall-mounted regulators are best for professional and commercial use. Thus, you can make sure that your compressor will always have the proper CFM and air pressure.

  • Spray Gun

Of course, all of the mentioned things above will be nothing without a spray gun. Thus, be sure to have a spray gun before anything else.
