An air compressor for painting cars operates by breaking up paint with pressurized air, and using that pressure to produce a fine mist of paint through a nozzle. The air compressor for auto painting delivers air in a strong enough flow that the paint is turned into a fine, liquid particulate, which is ideal for an even coat over the vehicle. Based on the size of your operation and the types of auto painting you will need to complete, compressor criteria may differ.
You might invest more When you select an air compressor for a car painting shop, where you need continuous airflow to spray gun, you should consider a bigger sized air compressor for heavy-duty performance. It would be best if you considered a 60-gallon air compressor, which one equipped a 5HP motor and capable of producing a minimum of 10CFM. If you are a hobbyist painter and involve in weekend painting at your home garage, a 6-10 CFM air delivering capable air compressor is a perfect fit to handle your criteria. The benefit of having a big-sized air compressor unit for performing nailing tasks, driving auto repair air tools is that it may use auto painting and furniture painting jobs at the home garage.
If you have a spray gun or you’re looking to purchase one for a painting project at home or in the workshop, you may now be wondering what size air compressor you need to run your spray gun. The small Neiko spray painting gun requires 4.5 CFM, if the use was intermittent and only needed 25% of the time, then the spray gun only requires 1.25 CFM. Therefore, this compressor would be capable of providing that that CFM. However, if you are required to use the spray gun on a 50% duty cycle, the spray gun would require 2.25 CFM. The air compressor running at its recommended 50% duty cycle would not be able to provide the amount of CFM required by the spray gun. Well Jan, since you can get about 4 CFM of compressed air at 90 PSI for each horsepower of electric motor size on the compressor, your compressor should, theoretically, give you about 12 CFM at 90 PSI. However, if you are running your 3 HP compressor on a 120 volt supply line, then you sure are not getting that 12 CFM at 90 PSI, since, in my opinion, there isn’t enough power in a 120 volt line to power your compressor motor enough to give you that flow and pressure.
With a small air compressor tank you simply don’t have the air volume to paint an entire car at one shot. You can take a chance and paint the entire car at one shot if you can hear and feel the air pressure drop and adjust accordingly. The tricky part YES, you can paint the car in steps with a smaller air compressor but you may run into problems with overspray on the clear coat stage.
In this article, we’ll talk about how you can choose the right air compressor to power your paint spray gun. It’s not the force of the air, CFM refers to the quantity of air the air compressor can produce at a certain pressure, say 90 PSI. The CFM is arguably the most important parameter you need to check for if you’re shopping for an air compressor for your spray painting project or business. After you determine the CFM of the spray gun, you need to make sure that the air compressor you choose produces more than the CFM of the spray gun.
While some air spray guns have a rating of lower than 10 CFM, we’d recommend your compressor CFM for spray painting is at least 12 CFM. For professionals, this figure may need to be higher – the important thing is you’ve checked your spray gun’s CFM requirements and chosen a compressor that exceeds that figure. 24 litre Air Compressor and Spray Gun Kit Secondly, our punchy 24 litre, 9.6 CFM compressor is fully equipped with a HVLP, gravity-fed professional spray gun, 10m rubber air hose, spray gun regulator with gauge, mini air filter and water trap and 2 quick couplers. 100 Litre Air Compressor & Spray Gun Kit Finally, our 100L, high-flow air compressor and spray gun kit will provide you with everything you need to quickly and efficiently complete any spray painting work you want to carry out.
The gallons of the air compressor are nevertheless less critical compared to the CFM an air compressor brings out. As stated above, the CFM rating is one of the considerations in choosing the size of the air compressor to paint your car. It is recommendable to select yourself an air compressor with up to 60 gallons volume tank, 5-6 Horse pipe compressor, 14-18 CFM ratings, and up to 90 PSI. At the end of the day, the most crucial thing is purchasing the best performing compressor efficient in painting your car and powering other air tools.
First, you need to decide on what paint gun you’re using to paint your car. Just like paint guns, there are large high-end compressors that will put out the air needed, and there are smaller air capacity compressors that will have a high CFM rating and can keep up with airflow needed with no issues. If you don’t have the need or shop space to get an air compressor for painting, you can look into self-contained turbine-style paint gun kits.
