Paint sprayers require a compressor with a large tank, preferably 50 gallons or larger, in order to keep up with the spray gun. As others have said, spraying paint is usually NOT a question of pressure, but rather VOLUME of air. A typical spray gun will require low pressure and HIGH volume, MUCH more than any standard compressor. This, for example, requires between 0 and 70 PSI, but 12 CFM.
Or, this one requires 10 to 14 CFM. And those numbers are always the minimum. For safety, it must be higher than that, or the compressor will work constantly to keep up, or it may have to stop periodically to catch up. Also, don't forget to check the warranty conditions when buying expensive tools such as an air compressor.
This 1.4 mm spray gun from PNTgreen is an average offering that has an average air consumption of 6 CFM according to its technical specifications. It doesn't matter if you need to spray paint old furniture (in your home or office) or if you want to make the task of nailing and installing moldings a little easier, choosing a good heavy-duty air compressor may be your solution. Also, remember to wear gloves and safety goggles when using an air compressor for painting furniture and for almost any home renovation work. Again, it's essential that you check the recommendations for your specific model, but the PSI of your HVLP gun is likely to be between 25 and 30 PSI for something like using an air compressor to spray cars, increasing to 40 PSI in some cases where more atomization is needed.
Instead, move the compressor to a warm location so it has a chance to warm up and work well. Therefore, if you plan to buy a compressor for larger jobs, it's good to buy a larger two-stage motor. Well, to be frank, there are several reasons why you might consider an air compressor and a paint sprayer. There are a few key considerations to consider when finding a suitable air compressor for a spray gun.
Similarly, another important factor to consider is the power supply that a compressor uses to operate. When you are going to buy a compressor with more “blow” as mentioned above, you should also consider oil. Although if it is a small compressor, it will work quite a bit to keep up with the spent air from a paint gun and you can have problems if you don't have enough pressure. However, despite all your efforts and preparations, you may still have problems with air pressure.
In general, a portable air compressor can be used to blow air for cleaning, for filling tires and other inflated products, for nail guns, and of course they can be used in a paint gun (for painting a house or even a car). However, to understand what capacity the air compressor has to deliver CFM continuously, you must multiply the CFM rating by the percentage of the duty cycle.
