man using Porter Cable PXCMF220VW Portable Air Compressor

Every good tool collection needs a stout compressor to power the pneumatic tools. From nail guns to paint sprayers to air-powered vehicle lifts, almost every type of tool comes in a pneumatic version that produces reliable power when needed, provided it’s backed up by a compressor that can supply enough air and pressure.

If you’re looking for a compressor for your garage or workshop, a 20-gallon tank offers the right amount of air to keep your projects moving so, you’re not constantly waiting for the tank to refill. But that doesn’t mean that just any 20-gallon compressor will do.

You would be pretty disheartened to purchase that new compressor just to discover that it can’t power your pneumatic tools! We don’t want that to happen to you, so we decided to test some of the best and most popular 20-gallon air compressors on the market. Below, we have short reviews comparing each so you can see how they stack up.

  • The 10 Best 20-Gallon Air Compressors

    1. Industrial Air Belt Driven Air Compressor – Best Overall

    Industrial Air IL1682066.MN Belt Driven Air Compressor

    This belt-driven air compressor from Industrial Air was the top performer overall. It has a powerful 1.6 horsepower motor capable of moving up to 6.2 CFM of air at 40 PSI, making it one of the most capable compressors we’ve seen. This compressor produces a maximum of 135 PSI, which is plenty for operating pretty much any type of tool.

    However, it is pretty noisy, running at about 100 decibels, but it’s reliable and includes a 2-year warranty. This compressor features a dual-voltage motor. It’s wired for 120V electricity when you get it, but you can easily convert it to 240V if desired.

    Large pneumatic tires make it easy to move around the workshop, though at about 160 pounds, you probably won’t want to move it often. Overall, we think this is the best 20-gallon air compressor you can buy this year.

    Pros
    • Wired for 120V and convertible to 240V
    • Max pressure of 135 PSI
    • 6 HP motor moves up to 6.2 CFM at 40 PSI
    • Large pneumatic tires make it easy to move
    Cons
    • Runs at about 100 dB

    2. WEN 2202 Portable Vertical 20-Gallon Air Compressor – Best Value

    WEN 2202

    Most of the 20-gallon compressors we tested were pretty pricey, making them difficult to afford for most hobbyists. However, the WEN 2202 Portable Vertical Air Compressor offers a more affordable solution. That doesn’t mean it’s lacking performance, however. The WEN 2202 is well designed, with smart additions like the large wheels and handle that make it easy to move. It helps that it only weighs 86 pounds.

    Performance-wise, the WEN compressor creates a max airflow of 5 CFM at 40 PSI and a maximum pressure of 135 PSI. At 90 PSI, it makes 3.8 CFM, which is enough to power most standard air tools, though some tools will require more airflow. For such an affordable compressor, we were surprised to see that it has a 2-year warranty, helping to make this one of the best 20-gallon air compressors for the money.

    Pros
    • Reasonably priced
    • Max airflow of 5.0 CFM at 40 PSI
    • Max pressure of 135 PSI
    • Warrantied for two years
    • Large wheels with handle for easy transportation
    Cons
    • Not enough airflow for some larger tools

    3. DEWALT Portable Air Compressor – Premium Choice

    DEWALT DXCMPA1982054 Portable Air Compressor

    This DEWALT portable air compressor is more expensive than most of the others we compared it against, but it also provides superior performance that we feel warrants the higher price tag. To start, it can supply a maximum pressure of 155 PSI, which is higher than the compressor from Industrial Air that earned our top recommendation.

    It also moves an impressive 7 CFM of air at 40 PSI, which can power just about any pneumatic tool. You’ll find a stout 1.9 HP motor installed on this compressor. Despite its power, it’s pretty quiet, operating at just 76 decibels. The motor is also dual voltage, so you can wire it to work with 240V electricity, though it’s wired for 120V from the factory.

    At a hefty weight of 166 pounds, this compressor isn’t the easiest to move. Making matters worse, the handle doesn’t feel secure and tends to flex while moving the compressor. But with such excellent stats, we can overlook the lack of mobility.

    Pros
    • Maximum airflow of 7 CFM at 40 PSI
    • Supplies a max pressure of 155 PSI
    • Dual voltage motor can work with 120V or 240V
    • Powerful 1.9 HP motor
    • Runs quieter than other compressors at 76 dB
    Cons
    • It’s pretty pricey
    • The handle doesn’t feel secure

    4. Porter Cable PXCMF220VW Portable Air Compressor

    Porter Cable PXCMF220VW Portable Air Compressor

    It didn’t quite earn its way into our top three, but this Porter-Cable air compressor is a very capable device with great features. With an operating volume of 84 decibels, it’s quieter than most compressors in the price range. It’s also capable of higher pressures up to a maximum of 150 PSI.

    At 40 PSI, this compressor will move five CFM of air, so on paper, it can power most air tools without issue. In reality, this compressor had trouble keeping up with many of our bigger tools. The tank doesn’t seem to fill up fast enough for tools at the top end of this compressor’s capabilities.

    We like the oil-free motor that requires almost no maintenance. Usually, oil-free motors are obnoxiously loud, but this one is a nice change. However, the fittings on this machine were leaking when we got it, so we had to tear it down and Teflon tape them all. Still, considering the quiet operation and low-maintenance motor, the Porter-Cable is a great unit overall.

    Pros
    • 84 dB operation is quieter than most
    • 150 PSI maximum pressure
    • The oil-free motor is very low-maintenance
    • Moves 5.0 CFM of air at 40 PSI
    Cons
    • Many fittings leaked from the factory
    • Fills slowly and has trouble keeping up with air tools

    5. Campbell Hausfeld DC200000 Air Compressor

    Campbell Hausfeld DC200000 Air Compressor

    Campbell Hausfeld is known for making quality air compressors, so we were pretty disappointed with the poor performance we saw with this one. It can supply up to 150 PSI, which is more than many competing models. It’s also very lightweight and portable at just 92 pounds, which is much lighter than many compressors we compared it to.

    We appreciated the low-maintenance, oil-free motor, but we wish it made more power. At 90 PSI, it moves just four CFM of air, so it will have difficulty powering some pneumatic tools. The motor is just 1.3 horsepower, which is not as stout as some we’ve tested that produced 2 horsepower or even more.

    It wouldn’t be too bad if that were all that was wrong with this compressor. But we don’t think this compressor is built as well as others. After a few weeks of light use, it developed a leak at the pressure switch, drastically reducing its usefulness. For the price, we were hoping for better longevity.

    Pros
    • Can supply up to 150 PSI
    • Low-maintenance oil-free pump
    • Weighs just 92 pounds
    Cons
    • Developed a leak at the pressure switch
    • 3 HP motor isn’t as powerful as competitors

    6. NorthStar Single-Stage Portable Electric Air Compressor

    NorthStar Single-Stage Portable Electric Air Compressor

    The NorthStar Single-Stage Portable Electric Air Compressor is a very capable device that’s held back by obvious oversights. Thanks to the dual voltage two HP motor, it makes plenty of power. It has a 6-foot standard power cord for 115V operation but can also be rewired for 230V electricity. At 40 PSI, this compressor delivers six CFM of airflow, which is plenty to power just about any tool you throw at it.

    Or, it would be if it weren’t for the 0.25-inch air pressure regulator bottlenecking the airflow. This prevents the compressor from being able to run larger air tools. We were able to remedy the issue by swapping it for a larger regulator, but we don’t think you should upgrade such an expensive compressor because of a factory oversight.

    Even though this is a powerful compressor, it’s also on the quiet side, operating at about 80 decibels, which we were thankful for in our workshop, where the sound gets amplified. But the drain valve was a different story. It’s positioned on the side, so you must tilt the compressor to drain it effectively. Even then, there’s no way to evacuate all the condensate.

    Pros
    • Moves 6.0 CFM at 40 PSI
    • Dual-voltage motor will run with 115V or 230V
    • Powerful 2 HP motor
    • Runs at 80 dB
    Cons
    • 25-inch air pressure regulator holds this compressor back
    • Won’t run heavy air tools with the current regulator
    • Drain valve is poorly positioned and won’t evacuate all the condensate

    7. Stealth SAQ-12018 Ultra Quiet Air Compressor

    Stealth SAQ-12018 Ultra Quiet Air Compressor

    If the operating volume were the most critical factor when comparing compressors, the Stealth SAQ-12018 Ultra Quiet Air Compressor would be at the top of our list. It’s the quietest of all the compressors we tested, running at just 68 decibels.

    Just because it’s quiet doesn’t mean it’s weak. The Stealth SAQ moves a respectable 6 CFM of air at 40 PSI, so there won’t be many air tools it will have trouble powering. Its motor pushes 1.8 horsepower, allowing it to fill the tank in just 70 seconds.

    Weighing in at just over 120 pounds, this is a pretty hefty compressor that isn’t easy to move. Most similar compressors are top-heavy, but this one seems worse than others. Once you start tilting it back so you can wheel it, the tipping point comes very quickly, where the weight will try to pull it to the ground, which might be useful when locating the release valve if it weren’t so difficult to stand upright again!

    Pros
    • Very quiet with 68 dB operating volume
    • Moves 6 CFM at 40 PSI
    • Powerful 1.8 HP motor fills the tank in 70 seconds
    Cons
    • The release valve is difficult to locate and reach
    • Top-heavy design will fall if you tip it too far when moving
    • Difficult to move since it’s 120 pounds

    8. Craftsman CMXECXA0232043 Air Compressor

    Craftsman CMXECXA0232043 Air Compressor

    At just 83 pounds, this Craftsman air compressor is easier to move than most of the others we tested against. It can also produce higher pressures, up to a maximum of 175 PSI. But it takes a long time to reach capacity, especially if filling the tank from empty. Expect to spend several minutes waiting for it to fill.

    This compressor is advertised as running at 80 decibels. In our experience, it seemed much louder, but we didn’t mind the noise. What we couldn’t ignore was the 50% duty cycle. You’ll have to spend as much time letting the machine rest as it runs, so expect a lot of downtime when using this compressor.

    Pros
    • Max pressure of 175 PSI
    • Weighs just 83 pounds
    Cons
    • Very slow to charge, takes many minutes to fill a tank
    • The pump seems louder than advertised
    • 50% duty cycle means you have to let it rest as long as it runs

    9. California Air Tools CAT-20015HP Two Stage Air Compressor

    California Air Tools CAT-20015HP

    Running at just 70 decibels, the CAT-20015HP Two-Stage Air Compressor from California Air Tools is pretty quiet, even though it can reach a maximum pressure of 175 PSI. However, that spec seems a bit misleading. It might reach high pressures, but this compressor doesn’t move much air. It can move just four CFM at 40 PSI, so you will have difficulty powering some pneumatic tools.

    Like most similar compressors, this one has a handle and wheels to make it easier to transport. But after moving it the first time, one of the wheel supports bent out of place! They don’t seem strong enough to support the weight of this compressor. Unfortunately, this is one of the more expensive compressors on our list. Considering the numerous quality compressors available for less, we can’t recommend this one.

    Pros
    • Maximum of 175 PSI
    • Quiet operation of 70 dB
    Cons
    • Poor airflow of just 4 CFM at 40 PSI
    • Overpriced for its capabilities
    • Weak wheel supports bent out of place

    10. Pulsar PCE6200 Vertical Electrical Air Compressor

    Pulsar PCE6200 Vertical Electrical Air Compressor

    Packing a heavy-duty 4-horsepower motor, the Pulsar PCE6200 Vertical Electrical Air Compressor should be the most powerful compressor on this list. It moves 6.2 CFM of air at 40 PSI, so it’s no slouch. However, it has a maximum pressure of 115 PSI, which is the lowest of any compressor we tested.

    We were disappointed that the Pulsar compressor wouldn’t operate many of our tools that required less airflow than it supposedly creates. Part of this is likely due to the fittings leaking when the unit arrived. Even though it’s more affordable than other units, we don’t think it’s a great value when it can’t even do what’s advertised.

    Pros
    • Powerful 4 HP motor moves 6.2 CFM at 40 PSI
    Cons
    • 115 PSI max pressure
    • Won’t power tools that it’s rated to
    • Fittings were leaking from the factory

    Buyer’s Guide: How to Choose the Best 20 Gallon Air Compressor

    When looking at 20-gallon air compressors, it’s easy to see that they all share a common tank size and assume they have the same capabilities. That would be a disastrous mistake, however. If you purchase the wrong compressor, it’s likely that it won’t perform the tasks you’re getting it for.

    To help put everything in perspective, we’ve written this short buyer’s guide that will cover the most important concepts that you need to understand before you decide on a compressor to buy.

    Understanding Compressors

    You can learn most of what you need to know about any compressor from two main measurements: CFM and PSI. It’s easy to confuse the two, but they’re not interchangeable, and if you get a compressor that doesn’t match your needs, you might find it can’t do what you want.

    PSI

    Pounds per square inch is how air pressure is measured. Most pneumatic tools will run on 70-90 PSI. The largest tools might need as much as 120 PSI.

    CFM

    This stands for cubic feet per minute, representing the volume of air that’s moved. A CFM measurement is represented at a particular air pressure to express the total amount of air moved at that air pressure. For instance, a compressor might be rated for 6 CFM at 40 PSI, which means that when it creates a total pressure of 40 pounds per square inch, it moves 6 cubic feet per minute of air.

    For the most part, this is the spec that you’ll need to match to your tools. Some smaller tools may only require 3 CFM of airflow at 90 PSI, while others might need 6 CFM or more at the same pressure. If your tool requires more air than your compressor can supply, it won’t run, or at least not effectively.

    Other Features to Consider

    CFM and PSI are the numbers that determine whether your tools and compressor are compatible, but they’re not the whole story. Other features can make one compressor preferable to another, even if they operate the same tools. Let’s look at a few of those traits so you can figure out what matters most to you.

    Operating Volume

    If your compressor is outrageously loud, you’re less likely to use it, and you’ll enjoy it less when you have to. This effect is exacerbated if your compressor is working indoors. The operating volume is measured in decibels, providing an easy way to compare each compressor’s noise. Granted, not all manufacturers list this specification.

    Some of the quietest compressors we’ve used operate around 70 decibels or a little lower. On the other hand, some of the louder ones were over 100 decibels.

    Portability

    Most people aren’t purchasing a 20-gallon compressor for its portability, but there are many times when you’ll need to move it. Sometimes, your hose isn’t long enough, or you want to reposition some of your tools and change your setup.

    You can expect your compressor to have a handle and wheels since most of them do. There are differences in wheels, but they only have a minimal effect on portability. There are pneumatic and solid tires, and you can find them in different sizes.

    The real difference that affects portability is weight. Some compressors weigh more than 150 pounds, while others weigh about 80. Remember, most of these compressors are vertical, so they’re pretty top-heavy. If portability is important to you, look for a compressor that’s on the lighter side.

    Conclusion

    The ideal 20-gallon compressor can power all of your pneumatic tools without making you go deaf, and it can do so without emptying the tank. Not all of these compressors that made it onto our reviews list were able to manage this, but three of them did it well enough to earn our recommendations over the competition.

    Our number one pick is the IL1682066.MN Belt Driven Air Compressor from Industrial Air. It has a dual voltage motor compatible with 120V or 240V electricity and a stout 1.6 HP motor that can move up to 6.2 CFM of air and reach a max pressure of 135 PSI.

    We think that the WEN 2202 Oil-Lubricated Portable Vertical Air Compressor is the best value. It manages a max airflow of 5 CFM and a max air pressure of 135 PSI. It’s also affordable and is protected by a 2-year warranty.

    When money isn’t a barrier, and you want premium performance, we suggest the DEWALT DXCMPA1982054 Portable Air Compressor. It has a maximum pressure of 155 PSI and a max airflow of 7 CFM at 40 PSI. Plus, it’s quieter than other compressors, with an operating volume of just 76 decibels.
