How to Choose a Portable Air Compressor for Painting
When doing a coat of paint with an air compressor, the most important thing you can have is a constant stream of air coming out. If the unit has to recycle on a regular basis, that means that you will have to take longer and you’ll run the risk of creating bubbles or diluting your paint with water collecting in the tank. As such, you’ll want to get a machine with a large enough reserve to last for hours on end, unless you want to spend days working on your project.
For auto painting, it’s best to go big and get something with 20 gallons or more, but if you’re low on space or funds, then you can go with something smaller.
This measurement is usually referred to as cubic feet per minute, or CFM. The higher the output, the more surface area you can cover in a shorter amount of time. However, if you are doing detail work, then you will want something with a lower output so that you don’t risk overdoing the paint. The other thing to consider is the pressure level. Most air compressors will deliver air at about 90 PSI (pounds per square inch), which is more than enough to operate most airbrush nozzles. Overall, just make sure that your compressor can deliver enough air at once to get the job done efficiently.
Because painting doesn’t require a lot of power, you won’t need a super deluxe motor in most cases. That being said, something with about half a horsepower or so will do the job just fine and ensure that you’re not putting too much effort into your paint job. While it may be tempting to opt for something bigger and more robust, the fact is that unless you’re doing a lot of other jobs besides painting, more is not necessarily better.
Finally, some compressors need oil to lubricate the machinery and keep it running smoothly. However, if you use that kind of machine for auto painting, you will get small flecks of oil into the paint, which could make it run or clump, depending on the situation. To ensure that this doesn’t happen you need to get an oil-free pump.
What Makes an Air Compressor Ideal for Painting?
When looking at different air compressors, the most important factors to consider when buying one for automotive painting are the size of the tank and the output level. If you’re doing broad strokes, then you’ll need something with a higher SCFM rating. Also, to make sure that you can do the job in one sitting, you’ll need a massive reserve tank that won’t have to recycle often.
The biggest challenge is making sure that you have a steady stream of air. If you have a limited tank, then you’ll have to pause every few minutes while the compressor recycles, which can get quite annoying over time. Also, the more it recycles, the more water will collect in the tank, meaning that you will have to drain it every few times it regenerates to ensure that your paint isn’t getting watered down.
To help reduce the amount of power and pressure you need, the best thing to do is get a gravity fed airbrush. This device puts the paint above the nozzle so that gravity does most of the work for you while the air just delivers it to the surface. This way you can reduce the amount of output you need, thereby enabling you to go with a smaller device. If you can opt for a larger one, however, we highly recommend it as it will take much less work overall.
What is the correct pressure for spray painting?
There are different ways used to paint the outside of a house or car. Spray painting as among the many methods you may use. It is important to note that spraying is not about pressure but air volume. Therefore, your spray gun should have low pressure and high volume. When the pressure is too little, you should expect to have an orange peel outcome with excess pressure causing you to waste more material than required as a result of unnecessary bounce-back.
The secret to doing everything right is by knowing the correct pressure. Most spray-gun makers give the air pressure information accompanied by their product. This is one way of helping you to attain the best pressure. Although there are additional factors that may affect the right pressure for spray painting, it is necessary to be careful not to have an inconsistent spray pattern Such pattern may cause streaking. Change the pressure if you change weather conditions.
