What Size Air Compressor for Painting?
There are different types of air compressors and paint sprayers to work on different projects. So, let’s see what size air compressors are needed for painting cars, houses, walls, miniatures, models, cabinets, and furniture.
Most of the cars get their paint job done by the spray painters, and you will need some specific types of air compressors. Usually, 30 to 50-gallon air compressors can easily paint a sedan or SUV without wasting time. But you will need a higher capacity for trucks, and we recommend air compressors with 70 gallons of capacity or more.
Painting big houses need some spray painting with professional or industrial painters and large-capacity air compressors. You can go with the low capacity ones, but you will need more time and effort to do this simple job. Get something in between 20 to 30 gallons for the perfect painting job.
It will be enough to paint the walls if you get an air compressor for painting your house. But you can go for an air compressor to only paint the walls, and we recommend something in between 15 to 20 gallons for the perfect painting job.
Miniature painting is done by professional craftsmen, hobbyists, and DIY lovers who like to do small projects and require painting some. You can go for the air compressors with a gallon’s capacity or less, which are the smallest. But beware of such compressors because you won’t be able to use these on other jobs.
You can get an air compressor slightly more capable than the previous ones to spray paint models without any problem. Air compressors with the capacity of 2 or 3 gallons can be perfect for painting models, and you will be able to do it quicker than the less capable ones.
6-gallon air compressors or some models with a little bit of higher capacity are perfect for painting jobs on cabinets. You can choose some models from popular brands, but make sure that you are maintaining the proper steps to do the painting.
