If you’re looking for a portable air compressor for cars that delivers better results, then this unit from Industrial Air is a fantastic option. Although it’s not going to provide the same kind of performance as one of the big models we’ve looked at, it’s perfect for auto enthusiasts who don’t want to invest a ton of money in their next paint project.
Because of its portable size, you still need to use a low-volume spray gun. Still, it delivers up to seven CFM at 40 psi, which is perfect for most jobs. As long as you’re okay with working more slowly and deliberately, then this is a great air compressor for painting cars.
As with the other model from Industrial Air, this unit comes with two tires that allow you to move around the shop, and it has a remarkable two-year limited warranty.
It can be said with the utmost of confidence that of the three wheeled air compressors for cars, Rolair’s is the most practical. Along with a pair of wheels it also features a pair of sturdy legs so that it is less likely of falling over and spilling. It is designed similarly to that of a lawnmower, with a handle that you can use to maneuver it. The handle is also capable of collapsing onto the top of the cage of the compressor, so you can occupy less room with it during storage.
With this considered, it is a great portable compressor for car tires with a large handle as if they designed this for women and weaker men in mind. While not as efficient as top end industrial kits, it performs decently for a large cut in price. It is equally as loud, though, so do not expect to hear a softer or quieter engine.
While it may require you to lean over to connect a hose or turn a dial, the settings are pretty straightforward and easy to use. While it does require oil in order to run, it is very simple to pour in oil and does not require a funnel or other instrument.While it is rather small in size, it feels like an industrial quality machine that could take a beating, weighing in at over 100 pounds.
Getting back to professional-grade portable air compressors for painting cars, this model from Campbell Hausfeld is probably at good as you’re going to get (at least with ordering online). It’s massive tank, and high CFM output ensures that you can use it without any downtime. If you’re trying to make your next auto painting project run smoothly, this is the machine to buy.
First of all, the air output on this machine is more than enough for most spray guns. Although it’s still a little on the low side for some HVLP models, you get up to 14 CFM at 90 psi, which is enough to power through your next paint project with ease.
Secondly, the 80-gallon tank enables you to work uninterrupted for much longer. Also, since it doesn’t have to recycle as often, you won’t need to empty your moisture trap as often, either. Overall, this is our top recommendation for professional auto painting.
Powermate is well known for quality tools and machines with high levels of productivity and efficiency, and the Powermate Vx PLA4708065 is no different. This steel portable air compressor for car painting is sure to be well worth the hefty investment. While it weighs in at over 350 pounds, it’s a reliable portable kit for any industrial workshop. Bolting to the ground is highly recommended to make sure that the machine is always stable and secure.
With that said, you will need to move all your equipment, rather than move the compressor for tires to each piece of equipment. This car painting kit is over 6 feet tall, so while it is very heavy to move and carry, it is very convenient when it comes to examining it.
All of the valves and adjustables are right in front of you, so no need to crouch down or hunch over in order to check or adjust something. This portable air compressor for car has three cylinders, 4.7 horsepower, and can provide 14 CFM at 90 PSI for extended periods of time, and will cool significantly. Even the most demanding of gas or air-powered equipment do not compare to this machine from Powermate. Its pump is lubricated by oil, but thankfully, oiling the pump is easy and does not need to be done very often. The oil level is easy to locate and identify, so you can easily tell when you have to lubricate the pump once more.
If heavy, immobile air compressors are just not your cup of tea, you will be satisfied to know about these other three kits with wheels; the first one being from NorthStar Portable. Northstar’s air compressor features a Honda GX160 engine. While it’s a powerful engine, it is designed to provide adequate combustion for greater output, which means that the engine won’t shake violently and will last longer than other engines on the market.
This compressor is great for painting car tires because is small overall, so it is easy for you to store or cart out of the way of moving vehicles. Smaller may not always be better, however, as its horizontal tank requires you to turn it on and adjust its settings as you kneel down.
When compared to the Powergate compressor for tires, Northstar’s compresor has slightly better horsepower, but it will take slightly longer to inflate equipment. It is also equally as loud to operate. Having the engine and motor on top of the tank will make it easy for you to find the main cause of a problem if something were to go wrong. However, it will take some time to learn about all the parts included in a car painting kit to know about how to fix a serious problem on your own.
For a compressor that is designed a little bit neater and is somewhat easier on the eyes and wallet, there is this portable air compressor for cars from California Air Tools. Judging by the name alone, you can expect no oil necessary and quieter operation.
While “Ultra Quiet” is a bit of a stretch, it offers noise that is over 25 percent quieter than industrial powered car painting kits. This means that you can be able to have better conversations with employees as the compressor does its job. The machine is also very light in weight; almost eight times lighter than Powermate’s kit.
This compressor is surprisingly affordable. But, this also means that it is not capable of delivering the same high-powered performance as industrial powered air compressors. Additionally, do not expect this machine to last as long.
When it comes to how to paint your own car, you can use a large air compressor to get the base coat, but what if you want to add some designs and flourishes to the body? If that’s the case, then this airbrushing kit is the perfect accessory to have in your garage.
What we like about this set is that it comes with three different airbrushes, as well as a full set of colors and pigments to get started. This kit enables you to plug and play without having to buy any additional equipment. It has a manual so that you can master it quickly, even if you’ve never airbrushed before.
Overall, this set is meant for arts and crafts, but you can easily use it to add some cool designs to your car. Whether it’s flames on the side or some small artwork elements, this set will open up your creative side. Also, it even comes with a one-year limited warranty.
If you are prohibited from buying a full-size air compressor for painting car tires, then this portable model is going to provide you with decent options at a lower price. Also, it is more compact and maneuverable, which allows you to move it from one side of the car to the other.
Performance-wise, this compressor delivers up to 6.2 CFM at 40 psi. This means that you have to use a low-volume spray gun. Also, the tank is only 20 gallons, so you’ll have to work a little slower to get the job done in one pass. However, for those on a budget or with limited work space, this is an ideal option.
The other thing that we like about this air compressor for cars is that it has heat sink by the motor. This helps reduce the overall wear and tear so that you can work longer without ruining the delicate components. Also, it comes with a two-year limited warranty.
Our next portable air compressor for car comes from DeWalt, and it’s the perfect tool to have on hand if you want to keep your car in pristine condition. Although this machine is not large enough to paint your auto from scratch, it’s ideal for spot painting or waxing. As a car enthusiast, you don’t need to have a massive compressor to keep your car looking its best.
Comparing the stats of this car painting kit, it’s easy to see why it’s ideal for small touch-ups. It delivers up to 5.0 CFM at 90 psi, and its compact design allows you to move it wherever it needs to go. Not only that, but the 4.5-gallon tank ensures that you can do spot painting quickly and easily.
Another reason to get this compressor, ideal for car tires painting, is that it’s super quiet. Working in the garage doesn’t have to be deafening, and at 79 decibels, this is a whisper compared to some other car painting kits out there. Finally, it comes with a one-year limited warranty.
As we mentioned below, having a large size air compressor ensures that your painting job can go smoothly. Although you could try to paint your vehicle in sections, this will lead to an uneven finish, which will make it take even longer than normal. Not only that, but you will put more strain on your machine doing it that way.
Fortunately, with a 60-gallon capacity, you can work non-stop without interruption. This machine is also rated for continuous operation, so you don’t have to worry about running out of air and waiting for it to recycle.
Overall, we highly recommend this compressor for car tires (low-volume spray guns), as the CFM level is 10-11 (depending on psi rating). As such, it won’t allow you to work with an HVLP gun. Nonetheless, you can get some spectacular results with this machine.
When picking out an air compressor for cars and car tires, it’s imperative that you know what you need it to do first. For example, a unit that’s designed for operating with pneumatic tools is not going to provide the same kind of power and performance necessary to paint cars.
As such, the most vital feature to look at is the CFM rating. This stands for cubic feet per minute, and it refers to how much air is pushed through the hose at any given time. Since the purpose of a paint sprayer is to turn the paint into tiny droplets, it’s necessary for the CFM rating to be high.
Most compressors that aren’t built for this purpose won’t have the right capabilities, which means that you will experience a lot of problems when trying to apply an even coat. Overall, you want to have a model that produces anywhere from 10-20 CFM to get the best results. On the higher end, they are what’s known as high-volume, low pressure (HVLP) compressors.
Another primary issue with air compressors for cars painting is that many of the ones built for other applications are not powerful enough to cause the kind of atomization that you need for paint. The reason for this lies in how the motor is set up. Many models are single stage, which means that they produce less CFM per horsepower. On average, they have one CFM per HP. Since you can’t find compressors with more than 5-6 horsepower (without getting massive), you have to go with a two-stage model instead.
The benefit of dual-stage air compressors is that they increase the output without requiring a lot of energy to do so. Rather than delivering CFM on a one-to-one ratio, they can do about 4:1. This means that a three-horsepower motor can provide 12 CFM, which is more than enough for standard spray guns.
When picking out your power needs, it’s also essential to pay attention to the noise level. More horses means that the machine will be a lot louder, so see if the unit has any elements that can reduce the sound level. Check the overall decibels for comparison.
If you’re a professional painter looking for an air compressor that can handle your work day in and day out, then you probably can get a giant machine that will be stationary in your workshop. A 20-40 gallon will provide more than enough reliability and performance to ensure that you don’t have any issues while working.
However, for at-home paint jobs, you don’t want something that massive. First of all, it will be much more expensive than is reasonable, and you probably won’t have that much space. Thus, you will have to spring for a smaller 10-15 gallon compressor that comes on wheels.
When looking at different models, however, you’ll notice that many of them are a lot smaller than that. So why do you need so many gallons? Well, when it comes to painting, the volume is critical. To get even coverage, you have to be moving a lot of air through the system at all times.
So, if you used a portable air compressor (i.e., four or five gallons), it would be recycling every few minutes, which will slow your work down to a crawl. Having a larger system ensures that you can keep painting without having to wait for the compressor all of the time.
Here are a few additional features that will make your next painting project a breeze.
Moisture Trap: compressed air is cold air, which means that water droplets are going to form. However, you don’t want water mixing with your paint as it can cause it to bleed or come out unevenly. Some professional-grade models will come with a moisture trap, but you should buy one separately if it doesn’t.
Oil-Free: like water, you can’t have oil messing up your paint finish. Rotary screw or some reciprocating machines don’t use oil to lubricate the system, which ensures that your air is clean.
Although buying the right painting kit for cars is an essential step in getting started, other components have to be considered as well. When setting up your paint station, you will want to have the following parts (in order). We’ll go into further detail about each one and the kind of features they should have.
Compressor - Filter/Regulator - Air Hose - Regulator - Spray Gun
We’ve already discussed the compressor in detail, but what about the other components? Here is an overview of what to look for with each.
Filter/Regulator: as we mentioned, the air coming from the compressor has to be both clean and dry. Also, you don’t want the pressure to drop while you’re working, so it’s imperative that your connections are tight and work well for the kind of sprayer you’re using. The filter should remove moisture and oil (if necessary), as well as enable you to adjust the pressure coming out.
Air Hose: for HVLP spray guns, you need a hose that is at least 5/16 inches thick. For lower volume options, at least ¼ inch is okay. Also, make sure that it’s not too long, as length will cause a drop in pressure. Try to get a hose that is no longer than what you need to get the job done.
Regulator: this can either be wall-mounted (for pros) or gun-mounted (for personal projects). The former will ensure proper pressure and CFM at all times, whereas the latter may not be as reliable, depending on the gun you’re using.
Spray Gun: this is the component that will dictate everything else. For example, an HVLP gun requires more CFM, less pressure, and a wider hose. Before picking anything else, choose your gun first.
As you can imagine, this kind of project is not for the faint of heart. Painting the car or the car tires is the last step, after sanding, cleaning, and priming, so it shouldn’t be attempted unless you a) know what you’re doing, or b) have the time, patience, and budget for it.
There are a few different air compressors sizes that you can use, so let’s discuss the requirements of each type. This will help you get a better idea of the model you should choose to get the job done the right way.
HVLP: since these don’t require a lot of pressure, you can get away with a compressor that delivers anywhere from 40 PSI or less. However, since they do need a ton of air to get the results you want, you have to make sure that your machine is adequately sized. For most HVLP sprayers, you’ll need at least 30-40 gallons, unless you want to put more strain on both yourself and the compressor.
LVLP: low volume, low-pressure spray guns are the better option if you’re not a pro looking to do this for a living. These guns cost a bit more, but they don’t require as much CFM, which allows you to go smaller. On average, you’ll need a 15-20 gallon compressor to ensure that you get even coverage, although bigger is still better so that you can work uninterrupted.
Standard Spray Gun: for those who don’t care about having a floor-model finish, you can save a lot of money by getting a gun that doesn’t have extra bells and whistles. You will have to look at the CFM rating on the gun itself, but most of these can work with about 15-20 gallon compressors as well.
Overall, you don’t want to go lower than 10 gallons, unless you are doing airbrushing artwork on your vehicle. These guns require a lot less pressure and air, so you can go with a compact unit instead.
In the end, this process is somewhat complicated, which means that there can be a wide range of issues that you encounter on the job. Although we can’t discuss every problem that comes with painting cars, here How to Fix common issues with air compressors and spray guns are some situations that you will likely find yourself in from time to time.
Low Pressure: if you’re working with a large enough compressor (i.e., 50-60 gallons), then the culprit is likely a connector leaking air or the regulator not working properly. If you’re using a smaller machine, then you should check the length of your hose, or wait for the pressure to build back up.
Tailing: this happens when the air coming out doesn’t match the work you’re doing. In this case, slow down and allow the compressor time to produce the amount of air and pressure you need.
Dripping: most likely there is water in the line. Your moisture trap may need to be emptied, or you might have to use a dryer instead. Also, the heat and humidity of your work environment may be adding more water to the line.
Bubbling From the Spray Gun: your air compressor is not producing the CFM necessary. Check your connectors and the regulator to ensure that there’s not a leak.
Splattering: the paint is not being sprayed evenly. Usually, this happens when you’re running low.
Uneven Finish (Orange Peel): either you’re not painting with proper technique, or the surface of the car was not cleaned thoroughly before you started. In that case, you’ll likely have to remove the paint and start over.
As such, the ideal candidate for these air compressors are either hardcore car enthusiasts who love rebuilding and renovating cars from scratch or professional painters who want to make a living at painting.
In either case, you want to make sure that you have the right car painting kit, as having something too small or too ineffective will make your work seem endless.
However, if you’re more of a hobbyist and you don’t need all of that power, then the Industrial Air ILA1883054 is your best bet. With a 30-gallon tank and 7.0 CFM rating, it’s more than enough for either spot painting or doing the whole thing. Just make sure that you get a high-quality filter and moisture trap to keep your paint in prime condition.
