Spray painting a car is one of the most demanding tasks for an air compressor, especially if you want a professional-quality finish. And the SS5 has the power and specs to handle the job. High-quality paint guns demand a high volume airflow and need to be operated for long periods without interruption. The SS5 meets that challenge with an ample 18.1 CFM, a large 60-gallon tank, and strong 5-horsepower output. The SS5 requires a 230-volt power source, though, and at 310 pounds it’s far from portable.
Pros & Cons
Large 60-gallon tank lets you operate the compressor for long periods without it needing to pause and refill
High 18.1 CFM provides plenty of air flow for most professional-caliber paint spray guns
While high, its price is hundreds of dollars less than many other heavy-duty compressors
More expensive than portable air compressors

Methodology
Forbes Wheels compared the specs, features, and pricing of dozens of portable and stationary air compressors that would be suitable for home garage use, and we checked expert and user reviews to identify where people have had problems with them. We looked for popular, highly rated compressors that represent the best overall values for people with different needs.
What size air compressor do I need for my garage?
This common question is like asking what size engine you need in your car; it depends on what you use it for. By “size”, many buyers focus on the tank size, which is measured in gallons. So, we’ll start there, although this only gives you part of the picture. Because a compressor’s tank is used to store compressed air, the bigger it is, the longer you’ll be able to work without the compressor having to pause and refill the tank. That’s why a compressor with a one- or two-gallon tank will have to stop and refill a lot more than one with a ten-gallon or larger tank. For jobs that don’t demand continuous pressure for extended periods, a smaller tank is fine. But a spray painter, for example, is best used with a larger tank so the stream of paint doesn’t get interrupted too often. For spray painting a car, which demands long periods of continuous application, experts recommend a hefty 60-gallon tank or larger.
What other specs should I look for when buying?
In addition to tank size, other critical considerations are a compressor’s PSI (pounds per square inch) and CFM (cubic feet per minute) ratings. Think of the PSI as how much force the air has (good for, say, pressure washing or inflating a tire) and the CFM as the volume of air that the compressor can deliver on a continual basis (critical for, say, spraying paint or operating an orbital or disc sander). Both specs affect which tools the compressor can power. Before buying, check the manuals or spec sheets for any tools you plan on using to see their PSI and CFM demands and note the highest ones. Then be sure to get a compressor that delivers a little more than that, which will give you a reasonable margin for error.
How much power does it take to operate air tools?
Most air tools require about 70 to 100 psi, which all of our recommended models can deliver. For inflating tires, you’ll need a compressor that can equal the highest recommended psi for your tires. The CFM requirements of tools vary more. According to Garage Tool Advisor, tools that don’t need constant air, such as a nailer or staple gun, require an output of only 2 CFM or less. A drill, half-inch impact driver, ratchet, or air hammer could need about 3 to 4 CFM. An orbital sander can demand 6 to 9. And a disc sander requires as much as 20. Paint spray guns can range from about 4 to 14 CFM, depending on their use.
Is it worth getting a compressor with a lower noise level?
Yes. After tank size, CFM, and PSI, we believe a compressor’s sound volume is the next most important consideration. The volume of most of the compressors we looked at ranged from 60 to 80 dB. That doesn’t look like much on paper, but remember that for every 10 dB, the sound volume doubles. So, a compressor that emits 70 dB sounds twice as quiet as one that emits 80. And a 60-dB compressor is four times lower than that 80-dB model. Put another way, 60 dB is about the level of normal conversation, 70 dB is about the same volume as a vacuum cleaner or hair dryer, and 80 is about the level of a noisy restaurant or lawn mower. Volumes above about 85 dB are considered harmful to hearing. So, a lower noise level is not only easier on your ears, it can provide a more pleasant overall experience by letting you, say, listen to music or easily chat with somebody while the compressor is running.
Should I get an oil-free compressor?
Many portable compressors are now “oil-free” (or “oil-less”), which means they use interior parts with friction-reducing coatings instead of conventional oil lubrication. One of the main benefits is less maintenance because you don’t have to change the oil. Among the compressors we researched for garage use, all of the smaller models were oil-free, while it varied among larger, heavier-duty models. So, we’d consider the lower maintenance of an oil-free design to be a good tie-breaker if all of the other specs are similar.
What else should I know about air compressors?
If the compressor doesn’t reach to where you’re working, add more hose, not more extension cord. Why: Voltage drops off and the compressor won’t deliver full power.
At the end of the day, drain the tank: turn the compressor off, bleed off the air pressure in the tank, then open the drain valve in the bottom to release water in the tank. Why: Water in the tank leads to rust and rust years down the road may lead to the tank rupturing.
Don’t playfully spray a person with air from the hose. Why: People get hurt. High pressure delivered up close, especially if it picks up any metal particles, could damage the eyes. Kids should never see this; don’t let them pick up bad and dangerous habits.
