When looking for an air compressor for your paint gun, there are a few things to consider before making your purchase.
Most paint sprayers don't really need a lot of PSI in order for them to operate. Many of them function well at just 10 PSI.
This means a greater focus should be placed air compressor CFM or cubic feet per minute rating that is on each compressor.
A higher CFM means a faster overall air compression process, allowing the compressor to keep up with the demands your paint sprayer places upon it.
When you've found your preferred paint sprayer, it is important to look at what the CFM rating is on the compressor from the manufacturer's recommendation.
Then just compare that figure to what each air compressor has to offer and you'll be able to match up functionality and value.
This works even if you have some of the more rare paint sprayers, such as the HVHP [high volume high pressure] or LVLP [low volume low pressure] options.
This can become a problem for some paint sprayers. You'll find that some models will give you a 12-14 CFM rating.
That can be difficult to provide for any portable air compressor, which means you'll need to invest in a commercial grade dual-tank option.
The exception to the rule here is for air brushing, which uses low CFM spray guns for their delicate work.
These typically require very little PSI, so just about any air compressor will work.
#1. Just because your air compressor CFM ratings are less than recommended by the paint sprayer manufacturer doesn't mean you cannot combine the two tools. It simply means you will not be able to paint continuously.
#2. Small compressors can be chained together to create higher CFM levels when necessary. You can also add spare tanks to small portable compressors to get the results you need.
#3. Horsepower is an important consideration, but only when measured with CFM and PSI. A 1 HP air compressor that provides you 6 CFM at 40 PSI is adequate if your paint sprayer requires 4-6 CFM to operate.
#4. Always try to get the most CFM and highest PSI that you can afford. If you can get a 2 HP air compressors that delivers at least 8 CFM at 40 PSI, then you'll be able to use most paint sprayers fairly well without the need to chain additional tanks or compressors to your setup.
#5. Name brand air compressors tend to deliver more consistent results. This isn't always true, of course, but a name brand compressor generally comes equipped with a better motor and this can help you to squeeze out an extra CFM or two.
#6. Air compressors can generate a lot of heat while they are operating, especially the portable oil-less varieties that are used for basic DIY work. This can affect the final results of a painted surface if the work is being completed in an enclosed room. Having an enclosed area be well ventilated is important for personal safety, but it is also important for a smooth finish as well.
#7. Your air compressor should be installed in a room with good ventilation. A level floor is absolutely necessary for best results. It can be helpful with the larger models in this category to have vibration mounting pads installed as well.
#8. Your air compressor should be installed in a room with good ventilation. A level floor is absolutely necessary for best results. It can be helpful with the larger models in this category to have vibration mounting pads installed as well.
#9. Your air compressor should be installed in a room with good ventilation. A level floor is absolutely necessary for best results. It can be helpful with the larger models in this category to have vibration mounting pads installed as well.
#10. Your air compressor should be installed in a room with good ventilation. A level floor is absolutely necessary for best results. It can be helpful with the larger models in this category to have vibration mounting pads installed as well.

All compressors require some form of lubrication, just like your car, to protect against normal wear and tear, friction and heat.
Inside an air compressor, air is drawn in with a piston. Oil free air compressors come with a Teflon coating (or other type of chemicals) inside to lubricate the piston, pump and other parts. This means the lubrication is permanent.
Air compressors that need oil to lubricate the piston means that you will be adding oil on a regular basis. This naturally means that oil compressors will require more maintenance vs oil free.
Typically, oil free air compressors are cheaper because the designs are more basic and they have fewer parts.
It’s debatable which models last longer: oil vs oil free air compressors. When oil free compressors first came out, their durability was questioned. But the tech has come a long way since then and the difference in longevity is about equal.
Contractors claim that oil compressors are larger in size and can push out so much air that a few workers can use the compressor at the same time and not run out of air.
Oil compressors are less noisy than oil free compressors, which is important if you’re working indoors or in a confined space where noise may be an issue. Even though oil free compressors now come with noise reduction technology, you can still hear the difference.
There are two types of air compressors: positive displacement and Dynamic. Most, if not all the compressors listed in this post (and used in your home or shop) are positive displacement, single acting reciprocating compressors.
Check out the infographic and post below for details about the other types of compressors.
You need to have a pure flow of air for your paint sprayer to properly work.
If there is any moisture in the air that is being used to atomize the paint, then you will alter the viscosity of the paint delivered on the surface being worked on.
Solving this problem requires a filter to separate the moisture from the environment.
Tailing can also be a common problem when using paint sprayers with an air compressor.
This occurs because your pressure levels are too low. Instead of moving closer to the surface being painted to risk having the paint run, pause for a moment to let the pressure levels equalize.
Unless you have a massive compressor being used, there will be times when you’ll need to let your compressor catch up to the work you’ve been doing.
If you use your air compressor for multiple tools, such as a nail gun or a finisher, then you may find that there could be some oil contamination within your air hose lines as well.
This also changes the viscosity of your paint and can even prevent it from adhering correctly. In this instance, it is important to have lines that are specifically dedicated to the painting work you’re doing.
So, how do you make a compressor quieter? First, it’s a good idea to make sure that the noise isn’t because something is wrong with your compressor. Any rattling or metal type noises should be investigated right away.
Typically, the cheaper the compressor, the noisier it will be.
Design is a factor in the amount of noise your compressor generates. A compressor with an encapsulated motor (the motor is built with a metal case around it) will always be less noisy.
You can build an air compressor silencer box with foam panelling on the inside, (properly ventilated of course). This air compressor box will deaden the noise from your compressor. Some folks even wrap the motor in a blanket/mat that deadens the sound.
Remove some of the noise from impact and shock by installing rubber grommets on the motor. This absorbs vibrations and sounds, keeping them from spreading.
The exhaust is one of the main parts generating noise on your compressor.
The intake, where the compressor sucks in air, is definitely another one of the loudest parts. Otherwise called an air compressor intake silencer,you can also purchase them online. So go a bit more DIY and attach a full blown muffler to the intake on your compressor.
Check out how to do it in the video below.
Routine maintenance on your air compressor helps you to extend the life of your compressor. A few simple steps and about 30 minutes of your time will ensure to keep you spraying paint with your compressor. Don’t forget to check for leaks!

We love the 1 year warranty and the majority of Owners are super happy with their purchase.
If air is leaking from the main line regulator it could be the common O ring Issue. The O ring might not be seated correctly on top of the plunger, but instead at the bottom of the valve. This is because the regulator may not come fully tightened from factory, or it got loose during shipping.
Just fish it out and place it on top of the plunger. Make sure the regulator is on tight to prevent this from happening again.
You’ll need a quality air hose with brass fittings for your DeWalt compressor, but make sure you’re buying one that has Dual Male connectors to avoid being disappointed.
We recommend wrapping your air line connections with teflon tape to really squeeze every ounce of air out of this bad boy and maximize performance.
This air compressor is remarkably user friendly. We also love the fact that the Hausfeld 3 Gallon is designed to minimize the vibrations you’ll receive when it is running.
It works on a standard household connection and you can get it up to about 110 PSI if you give it enough of an initial charging time.
The CFM rating is a bit low, hovering around 0.5 for most users, so you won’t be able to use high CFM sprayers with this model unless you’re chaining it together with other units.
Get around that one issue and you’ll find that you can do just about anything with this little compressor.
This small high output compressor from Bostitch is a PSI monster. With 150 PSI max, you can run any tool from a sprayer to nailers without have to wait for the tank to refill.

The lightweight pancake design of only 13 lbs means this unit is one of the lightest and most portable of all the units we tested. So small you can store it anywhere, perfect for taking in your RV or motorhome without taking up a ton of space.
This air compressor really is value for money. Included is a 25 foot air hose, needle, needle adapter, 2 inflator nozzles, air chuck AND on board storage. We did find the hose to be a bit on the cheap side, so level up to a longer and better quality hose with brass fittings.
It’s also backed with a 1 year warranty.
With 100 to 110 Max PSI and 90 PSI operating, this unit can power most paint sprayers and brad nailers, but not impact wrenches or other air heavy tools. If you have a ton of nailing to do, this unit tends to recycle after 2-4 nail shots, so step up to the 3 gallon model for consistent air.
We had to wear ear plugs while using this unit during testing; it’s louder than the other models we used.
It is even strong enough to power a light-duty pneumatic tool, so there is plenty of power available for your paint spraying needs.
Perhaps the best feature of this model is its stainless-steel hose, which is strong enough to allow for the compressor to be mounted separately from the tank.
