Air Compressor Buying Guide
Now that you know which Air Compressor for painting are worth your investment, there are certain factors you must be mindful of when you purchase a Air Compressor
1. Horse Power (HP)
The horsepower is the power output of a motor or an engine. It is an indication of how powerful a motor is. A higher horsepower implies higher air pressure. For a portable air compressor, a value of 1-2 horsepower is typical. The 2 HP compressors are commonly used in many workshops and garages (non-industrial or DIY).
2. Max Pressure (PSI)
PSI (Pound-force per Square Inch) is the measure of the air pressure output of the air compressor. A higher PSI value means that the compressor can store more air in the tank. This will allow you to use the tools for a longer time.
Other important units are CFM (Cubic Feet per Minute) and SCFM (Standard Cubic Feet Per Minute). These indicate the volume of air that the compressor can deliver at a specific level of PSI. A high valued CFM is more suitable for applications like air wrenches and nail guns framing.
3. Tank Size
The compressors come with a wide range of tank sizes. Smaller tanks with a value of 4 to 6 gallons are good for projects like airbrush, brad nailer operations, or nail guns. For automotive works and other remodeling projects, larger tanks will be more suitable. They store highly compressed air at high pressures.
4. Oiled vs Oilless
The oiled compressors are traditional ones that need manual lubrication from you for continued operation. The oilless compressors are designed to have the pre-lubricating capability and do not require oiling by the user.
The oiled compressors are heavier when compared to their oilless counterparts. They are also noisier. Though oilless looks user-friendly for it's a maintenance-free feature, the internal lubrication must work properly for its continuous operation.
The size of the air compressor depends on the horsepower values. As this value goes up, the compressor gets heavier and larger. But they work great for a prolonged period. Since they have a vertical design, the space occupied is minimum. For DIY purposes like painting, portable air compressors can be chosen. They are handy, compactable, and light in weight when compared to the stationary compressors.
Below is a video of how you can set up and use a spray paint gun. Everything is explained in it for easy understanding, even if you are a complete beginner.
By now, you should have procured some idea about the air compressor products and their features. As we also discussed on the buying guide, you should be clear about all the key factors to check before you decide to buy an air compressor. Air compressors can be used in a wide range of applications, so your selection should be based on your intentions to use the same. For home-based uses, going for smaller air compressors will be the right option.
For high-end applications, you can invest a little more and go for larger compressors. Safety is the prime concern for such pneumatic products, so it is vital to check those features beforehand. As you can use the air compressors even for purposes other than painting, you won't regret the investment you make on air compressors.
