According to what criteria should you choose your air compressor for painting Car?
The volume of the tank
The capacity of the tank plays an essential role in the operating time of the compressor. Indeed, when the latter is empty, the compressor must restart its motor to compress a certain quantity of air again. This implies a waiting time. For long tasks such as painting or sanding, it is therefore interesting to opt for a well-sized tank, which is not the case for tire inflation or workshop cleaning.
Airflow
This is the air capacity returned by the compressor. The higher the flow, the more it is possible to use different tools and to benefit from sufficient power (the air delivery capacity is directly dependent on the horsepower of the compressor motor). The airflow is calculated in l / min or in m³ / h. To find the flow rate you need, read the air consumption requirement of your tools and multiply this number by 1.5.
Energy
The most powerful compressors are usually thermal, but models intended for homes and DIY enthusiasts are most often electric. In these electric versions, we find the classic connection to the mains, or battery operation which allows more mobility. Battery-powered compressors are portable models that perform basic tasks. Some compressors can also work with 12 V, which allows them to be plugged into the cigarette lighter socket of the car.
Lubrication
Portable compressors work without oil and therefore do not require any maintenance on this site. On the other hand, the more powerful models need to lubricate their cylinders, which inevitably involves minimum maintenance (topping up oil and draining).

Weight and bulk
Buy an air compressor based on available space and your ability to carry it. Models under 20 kg are easy to transport and compact. But for regular use, opt for wheeled models. Heavier and bulky, they weigh 20 to 150 kg. Some professional models are permanently fixed in a workshop.
Accessories
Depending on the type of compressor you buy, you will need a number of accessories. There is in particular the pressure switch which automatically triggers the motor whenever the tank falls below 4 bars. The pressure regulator is also useful, as is the pressure gauge indicating the air pressure in the tank. For large air compressors, a full stretcher may be needed to move it more easily.
Swivel wheels are suitable in tight, inflatable places if you need to move the compressor over gravel or sand. As for the direct tank outlet, it provides an alternative air outlet at 8 bars, in particular for impact wrenches. To regulate the heat of the head during prolonged use, the cooler will be essential. A swiveling air filter retains impurities from the ambient air, which will prevent damage to the compression head. A simple filter regulator provides clean, dry air at the outlet.

The different compression groups
The motor used to fill the tank with compressed air is called a compressor unit. There are 3 types of compression groups on the market.
Oil-free group
The oil-free group equips portable compressors. It is intended for occasional use, generally for short periods. The advantage is that you won't have to add more oil to lubricate. On the other hand, the service life is shortened. Note that it is often noisy.
Cast iron group
Unlike the oil-free group, the cast iron group benefits from better service life. The cooling of the group is also better given the optimal heat exchange due to the cast iron. This type of compressor unit is fitted to large compressors under heavy strain.
Aluminum group
It is the most widely used compressor unit. Indeed, it meets the needs of the majority of DIY enthusiasts. However, avoid using an aluminum group for professional purposes, as the cooling is poorer and slower than the cast iron group.
Air filter
Impurities in the intake air can damage the compressor unit. To prevent this problem, manufacturers have equipped compressors with air filters. Professional models also have filters at the tank outlet allowing them to provide clean, dry air.

How to use your air compressor?
- Use your compressor in a clean and open environment.
- Wear appropriate clothing for the work being done (protective glasses, gloves, and earmuffs.
- Before starting up, check the direction of rotation of the compression block and the oil level.
- Change the oil every 100 hours of use.
- Also, be sure to drain the condensation once a week and clean the air filter regularly.
- For any tank model, it is recommended to carry out a mine pass every 5 years to ensure that it works properly.
Maintenance of an air compressor
If you want the compressor to last, you will need to perform periodic maintenance. This is especially true for single-cylinder and twin-cylinder air compressors.
Air filter
A major drawback is the suction of ambient air: by sucking the air, the compressor unit also sucks up particles and dust that can damage pneumatic tools. Make sure it is clean to always have maximum efficiency and long service life.
The reservoir
The compression of humid air generates condensation inside the tank. So that this stagnant water does not eat away at the metal or freeze, manufacturers have fitted the compressors with a bleed screw located under the tank. Regular draining of the tank is necessary before a long period of inactivity. Portable air compressors are not affected.
Oil change and level
For single-cylinder and twin-cylinder air compressors, the oil level should be checked periodically. Add oil if necessary and change it at least once a year. Failure to lubricate a single or twin cylinder compressor significantly reduces its life.
Usage tips
An air compressor is a noisy tool, no offense to manufacturers who sometimes brag about their supposedly silent compressor. In use, wear earmuffs or at least earplugs. The compressor is also dangerous. To prevent accidents, learn about the operating pressures of your pneumatic tools.
In addition, some air compressors require periodic checks and inspections every 40 months. Many accidents occur due to water-eaten tanks or faulty pressure switches and pressure regulators. All the more reason to check everything before use.
For small pneumatic tools, use an air supply hose with an inner diameter of 6 to 8 mm. For large tools, use a pipe with an internal diameter of 10 to 12 mm. And to avoid loss of efficiency, maintain the same inside diameter from the air outlet of the compressor to the connection nipple on the tool.

Vertical or horizontal air compressor?
Vertical compressor
The vertical compressor is an oil-free device. It requires an outlet oiler to lubricate tools such as a drill or sander. This first model is easier to maintain thanks to the oil change. Compared to the horizontal model, the vertical compressor stands upright and therefore takes up very little space. On the other hand, it is less easy to move it.
Horizontal compressor
The horizontal compressor is also called a lubricated compressor. This implies that the air emitted by the horizontal model contains a little oil, which requires an oil separator filter for its use. The difference is also in the handling. The horizontal compressor is easier to move. On the other hand, it takes up much more space than the vertical type.
Verdict
These 2 configurations can give the same efficiency since they have similar air flow rates and regulation systems. Only manipulation makes it possible to differentiate them. To choose, above all determine your real needs. If saving space for storage and time for maintenance is the priority, the vertical compressor is for you. On the other hand, if you need to move often, it is better to use a horizontal compressor.

Tips
Pay attention to the time of use
It is important to know that an air compressor should not be used more than 50% of its actual operating time. As it expands enough energy, it must rest half the time to avoid the risk of overheating.
Consider adding an additional tank
Thanks to a pneumatic extension, it is possible to add an additional tank to your air compressor. This will not only allow you to increase the volume of air available but also to work in all practicality. Indeed, due to the absence of a motor, the additional tank is very light and easy to handle.
Limit the noise of your air compressor
The air compressor is quite a noisy device. To remedy this, take a sealed box and place it at the air inlet of the cylinder. Then connect the end of this box with an air filter trapped in a plastic box. Thanks to this sound trap, the noise of your air compressor will be reduced considerably.

Store it properly
Your air compressor should be placed in a location with a clean, dry air inlet. Indeed, subject to wet conditions, your machine may be damaged and present certain electrical malfunctions.
Carry out maintenance actions at suitable times
Note that it is important not to add or change the oil and fuel in your air compressor while it is running, or when it has been recently used. If this happens, there is a good chance that your device will catch fire and cause a fire.
FAQs
What Size Air Compressor Is Best For Painting Cars?
When it comes to painting cars, the size of the air compressor you need will depend on the type of paint gun you plan to use, as well as the size of the car and the scope of the painting project. Here are some general guidelines to help you choose the best size air compressor for your needs:
- Check the paint gun requirements: Different types of paint guns will have different air requirements, typically measured in cubic feet per minute (CFM) and pounds per square inch (PSI). Check the manufacturer's recommendations for your paint gun to determine the minimum CFM and PSI required.
- Consider the size of the car: Larger cars will require more paint, which in turn will require more air pressure to atomize and apply the paint effectively. If you plan to paint a larger car, you may need a larger compressor.
- Think about the scope of the project: If you plan to paint multiple cars or do a lot of painting, you may want to invest in a larger compressor to ensure you have enough air pressure to complete the job efficiently.
As a general guideline, a compressor with a minimum of a 60-gallon tank and a rating of 5-7 CFM at 90 PSI should be sufficient for most car painting projects. However, it's important to check the specific requirements of your paint gun and project before making a final decision.
How Many Cfm Compressors Do I Need To Paint A Car?
The required CFM (cubic feet per minute) of an air compressor for painting a car will depend on the type of spray gun being used. A conventional spray gun typically requires 7-12 CFM, while a high-volume low-pressure (HVLP) spray gun may require 10-18 CFM.
It's important to note that the CFM rating of an air compressor should not be the only factor to consider when choosing an air compressor for painting a car. The compressor should also have sufficient horsepower (HP) to keep up with the air demand, and adequate tank size to maintain consistent pressure.
In general, a compressor with at least 5 HP and a 60-gallon tank should be able to provide enough air for most automotive painting applications. However, it's always best to consult with the manufacturer of your spray gun to determine the specific requirements for your project.
Which Air Compressor Is Best For Painting?
The best air compressor for painting depends on several factors, including the type of paint gun you are using, the size of your painting project, and your budget. Generally, a compressor with a larger tank and higher CFM (cubic feet per minute) rating will provide more consistent air pressure, which is important for achieving a smooth and even finish.
For most automotive painting applications, a compressor with a minimum of 5 CFM at 90 PSI is recommended. However, for larger projects or high-volume spray guns, a compressor with a higher CFM rating of 10-12 CFM or more may be necessary.
Some popular air compressor brands for painting include California Air Tools, Quincy, and Campbell Hausfeld, among others. It is important to choose a compressor with a good reputation for reliability and durability, as well as one that is appropriately sized for your specific painting needs.
What Size Compressor Do I Need For Spraying Paint?
To spray paint, you will need a compressor that delivers at least 10-12 cubic feet per minute (CFM) at 90 PSI (pounds per square inch). A larger compressor, such as one with 20-30 gallons and a minimum of 5 horsepower, is recommended for larger painting projects or professional use. It is also important to choose a compressor with a regulator and water trap to ensure clean, dry air for your paint gun.
Which Compressor Is Best For Car?
The best compressor for a car depends on your specific needs. For inflating tires and powering air tools, a portable compressor with a tank size of 20-30 gallons and at least 2-3 horsepower is sufficient. For spray painting a car, you will need a larger compressor with a minimum of 10-12 cubic feet per minute (CFM) at 90 PSI and a larger tank size of 60-80 gallons to ensure consistent pressure and uninterrupted use.
It is important to choose a compressor with a regulator and water trap to ensure clean, dry air for your tools or paint gun. Additionally, consider the noise level and portability of the compressor if you plan to use it in a garage or workshop setting.
What Pressure Do You Spray 2k Paint On?
When spraying 2K paint, the pressure should be set to around 25-30 PSI (pounds per square inch) at the gun. However, it is important to follow the manufacturer's recommendations for the specific paint being used, as different paints may have different application requirements. It is also important to adjust the pressure and the spray pattern as necessary to achieve the desired coverage and finish.
How Many Cfm Is Hvlp?
HVLP (High Volume Low Pressure) spray guns require an air compressor with a CFM (cubic feet per minute) rating between 7-20 CFM at 40 PSI. The exact CFM requirements may vary depending on the specific HVLP spray gun being used.
Can I Paint A Car With A 50l Compressor?
It is possible to paint a car with a 50-liter compressor, but it may not be the most efficient or effective option. The size of the compressor needed for painting a car depends on factors such as the type of paint gun being used, the size of the air tank, and the air pressure required for the paint job.
If using a high-volume, low-pressure (HVLP) spray gun, a compressor with a minimum of 10 CFM at 40 PSI is recommended. However, a 50-liter compressor may not provide enough air capacity to maintain the necessary pressure and flow rate for extended periods of spraying. This could result in inconsistent paint coverage, clogs in the paint gun, or other issues.
It is important to consult the manufacturer's recommendations for both the compressor and the paint gun being used and to consider the specific needs of the paint job when selecting a compressor.
What Compressor To Use With Hvlp Spray Gun?
When using an HVLP spray gun, it's important to choose a compressor that can deliver enough air volume (CFM) and air pressure (PSI) to the spray gun. The compressor should have a minimum of 10-12 CFM at 40 PSI for most HVLP spray guns.
A 30-gallon air compressor with a CFM rating of 6-8 CFM at 90 PSI should be sufficient for most HVLP spray guns. However, for larger spray guns or continuous spraying, a compressor with a higher CFM rating may be necessary. It's also important to make sure the compressor has a large enough tank to maintain a steady air supply during spraying.
