Most paint sprayers need to be hooked up to some form of air supply. This means that only the airless paint sprayers and the HVLP get to work without being hooked to a compressor.
Over the years, air compressor shave witnessed so much change in design, use as well as performance. Compressors can be used for other purposes too, like air brush painting, inflating tyres, diving, sand-blasting and much more.
However, once you buy an air compressor you will realize that not all air compressors are designed for painting. Most air tools use air in bursts while paint spraying is a continuous draw. You will find that a compressor you bought draws only 25% of the time as you work, hence no quality finish but patchy work. As a result you will be needed to look for a better compressor.

Choosing the Best Air Compressor for Paint Sprayers
When shopping for an air compressor for your paint sprayer, you have to look at these three factors;
- When spraying paint with an air paint sprayer, a large volume of air should be injected into the paint to create atomization. This volume is measured in Cubic Feet Per Minute, hence CFM. This is a critical factor, what costs much in an air compressor. Quality HVLP paint sprayers need up to 20 CFM of air while conventional sprayers can use 10-15 CFM. Although there can be options for low CFM paint sprayers, their paint break up won’t be as good hence affecting your finish quality.
- Compressor type. There are different types of air compressors, which we will take a look at below, and you need to choose carefully. If you need sufficient CFM for painting, then you need a stage 2 compressor which will provide about 4 CFM of air per horse power of the compressor. You will mostly find a single stage compressor in hardware stores and shops and these ones deliver about 1 CFM per horse power. So imagine if you have a compressor with a horsepower of five, you won’t have any problem providing air into your sprayer.
- Additional options. Once you have the proper size of an air compressor, you should also consider the additional options.
Other things you ought to keep in mind include;
- When necessary, small compressors can be chained together to generate a higher CFM levels. Besides, you can add spare tanks to the small portable compressors so that you get the results you want.
- While operating, air compressors are likely to generate so much heat. This is especially the oil-less varieties which are used for basic DIY work. The end results gets affected.
- Some name brands offer air compressors that are more consistent. This might not be entirely true but generally, name brand air compressors come well equipped with a motor than others.
There are three different types of air compressors. They include;
- Reciprocating. A reciprocating air compressor is a positive displacement machine, it increases the pressure by reducing its volume. Reciprocating air compressors are also further classified into single-stage and double stage. Single-stage are used for pressures between 70 psig and 100 psig while two-stage are used for higher pressures between 100 psi and 250 psi.
- Rotary Screw Compressors. These compressors have two rotors within a casing where they compress the air internally. This is a positive displacement compressor, without valves. These are easy to maintain and use.
- Centrifugal Compressors. These compressors depend on transfer of energy from a rotating impeller to the air. They are dynamic compressors which produce high-pressure discharge by converting angular momentum. To achieve this, they rotate at higher speeds than other types of compressors. They are also oil-free by design with a continuous flow through them.
Choosing the right air compressor can be critical in ensuring you provide enough air volume for adequate atomization of your paint. But here we make it easy for you. We will review the top 5 air compressors for paint sprayers to make your journey to the shop a brief one and the whole experience as easy as possible.
