At under $200, this 20-gallon air compressor packs a powerful punch that competes closely with more expensive items on our list. The Industrial Air IT20ASMME is one of two horizontal models on our list, and also features the lightest build across the board at just 60 pounds.

Despite being pretty feather-light compared to most others we’ve picked out, the IT20ASME delivers a whopping 175 PSI of pressure. This puts it ahead – right next to the Husky model – in terms of sheer power and run-time length.

With its higher PSI, the IT20ASME can power up air-hog tools for longer periods of time without having to take too long to recover. This makes it a suitable choice for heavy-duty jobs that require long periods of tool use for completion.

Industrial Air IT20ASME -2

 

Another thing you’ll notice about this model from Industrial Air is that it seems relatively stripped down when compared with other more expensive choices. Two quarter turn valves on its side drain out water and air. Between them is a gauge to indicate pressure. Other than that, there’s not much else to see.

The rest of the controls are at the head of the cylinder where you’ll find everything else you need to operate the equipment. The package comes with a vertical base for vertical storage and four vibration isolating feet for horizontal. Along the sides are two welded handles that let you carry the thing around for transport.

Budget-friendly, efficient, and powerful, the Industrial Air IT20ASME can deliver premier functionality at a reasonable cost.

Porter Cable PXCMF220VW -6

Being oil-free model, the machine doesn’t call for too much of your maintenance effort. The compressor won’t need regular oil checks or replacements, letting you fire it up any time without worry of hiccups. This also means that the machine is capable of supplying air pressure to some of the most demanding tools for a much longer period of time without the need for frequent recovery.

To keep the motor safe from the dangers of wear and tear, the design was wired for a low-voltage start-up. This reduces the current draw on the motor and imposes a lesser starting torque. In effect, it doesn’t jolt the motor to life, instead bringing it to a gentle start that protects it from damage in the long-run.

Obviously, the Porter Cable PXCMF220VW fights for its position among the best 20-gallon air-compressors. Efficient, powerful, and low-maintenance, it would have made the perfect choice.
The only problems are that it can generate quite a lot of noise and its build isn’t as reinforced as you might expect. It won’t explode on you or anything like that, but it will leave room for a little doubt which can always play with your head when working with hazardous air tools.

Positives
  • Low-maintenance design doesn’t require time or effort for oil checks and changes
  • Powerful pressure output at 150 PSI
  • Fully enclosed working parts for greater protection for both you and the machine
  • Longer run-time for even the most demanding of air tools

Features

  • Air flow: 3.7 CFM at 90 PSI
  • Maximum pressure: 150 PSI
  • Oil-free: Yes
  • 83.8 pounds
  • Intuitive handle and frame design

Last on our list but definitely not the least is the Briggs & Stratton 074064-00. Another oil-free model, this design minimizes the need for checks and replacements, letting you work right off the bat without worrying about performance issues. At just 83.8 pounds, it might be heavier than the Industrial Air IT20ASME, but it still comes out as the best portable choice.

Why is that? Well, the Briggs & Stratton design boasts an intuitive handle and frame design that doesn’t just support the tank, but also protects the working parts. This holds everything in place, paving the way for a solid construction that can make any worker feel confident.

The frame – in combination with the heavy-duty never-flat tires – make it a dream to pull the thing around your job site. Whether you’re towing her over to your garage or across a gravelly work site, the Briggs & Stratton will feel exceptionally well put-together – no jingling or loosening parts.

Delivering 150 PSI of pressure, the model can sustain demanding air tools for longer run-times. Its powerful 1.5 horsepower induction motor also helps generate far more oomph, providing sustained performance for decades after purchase. Other than that, everything else is pretty much industry standard. Easy-access controls, air flow and pressure gauges, and a quick connect air outlet make it relatively convenient and effortless to use.

Now, for the downsides. While we’d hate to be a buzzkill, there are some features on the Briggs & Stratton that prevent it from rising through our ranks. The biggest issues users have with the model is its slow recovery and high noise level which sounds more like a roar than a gentle hum.

Positives
  • Easy to bring around a job site thanks to its lightweight build and intuitive handle and frame
  • Very well put-together, allowing confident, worry-free use
  • Sustains demanding air tools for longer periods of time
  • Heavy-duty motor can take years of use with no issues
  • Low-maintenance oil-free model
Negatives
  • Probably the noisiest of the bunch
  • Slow recovery means you’ll have to wait a while between tools before resuming your work

Buyer’s Guide

Even the most affordable 20-gallon air-compressors aren’t actually cheap. No matter what your purpose is, an air-compressor should be seen as an investment. That means taking your time, doing your research, and understanding exactly what each choice brings to the table to get a better perspective of which one will give the best value for every dollar you spend.

Needless to say, there are quite a few features you need to look out for if you’re buying an air-compressor. Knowing how each one of these factors add up should help you determine what you need and prefer, so you can opt for a model that won’t fall short of your standards.

Porter Cable PXCMF220VW -3

PSI Rating

One of the first things you need to consider before buying an air-compressor is its PSI rating. Most others would tell you to look into horsepower. But unfortunately, smaller air-compressors for residential use will rarely tell you its accurate horsepower rating. That’s mostly because big-box stores have managed to obscure the actual values to help advertise their wares. So, even if a machine claims to run on 1.5 or 2 HP, there’s no way to verify whether or not that’s true.

Instead, looking into PSI might offer a more accurate representation of the model’s power. PSI – or pounds per square inch – tells you how much pressure the machine can bust out during operation. The typical range for 20-gallon air-compressors is around 135 to 175 PSI. The higher the PSI, the more pressure you have to power your tools.

It pays to keep in mind that while that air travels through your compressor, it will lose some pressure through the hose and the coupler which will inevitably have leaks – no matter how seemingly insignificant. That means that even if you set your compressor to 90 PSI, the actual pressure delivered at the end might be slightly less.

That said, if you’re using air tools that require lots of pressure, you might consider buying an air-compressor with a higher PSI. That way, you can bump up the PSI settings to push 100 or 120 PSI to get the ideal pressure in your tool without overworking your compressor’s motor.

8 Best 20-Gallon Air Compressors 6

CFM Rating

CFM – or cubic feet per minute – is a measure of the volume of air that an air-compressor produces for every minute it’s turned on. Every tool requires a certain level of air volume. If the air-compressor falls short of that volume, then it may require a longer recovery period at regular intervals, delaying your work. That’s why some models tend to require that you put down your tools for a while especially if you’re using a demanding air tool or if you’ve been operating the equipment for too long.

CFM rating tends to change depending on the PSI pressure rating. Unfortunately, they won’t be too accurate either, just like the horsepower rating. When buying an air-compressor, the most important CFM rating should be the one corresponding to 90 PSI because that’s the pressure that most tools require in order to function.

Noise Level

Have you ever heard an air-compressor? You’d be surprised how noisy these things can get. And because the noise they generate can easily qualify as public disturbance noise, it would help to keep noise levels in mind before you buy. Knowing exactly where you plan to put your air-compressor should also provide some insight as to how much noise is too noisy.

Noise levels can be affected by the compressor’s motor and mechanism. For instance, oil-lubricated compressors have been developed to generate far less noise than their oil-free counterparts. Air-compressors that use a belt-driven motor also tend to be far more silent, letting you work even in residential areas without waking up the whole neighborhood.

8 Best 20-Gallon Air Compressors -1

Oil-Lubircated vs Oil-Free

To compress air and build-up air pressure, air compressors have a moving piston that moves up and down to allow air in and to press it down. The oil, as you might have guessed, works to allow the free movement of the piston. As the oil depletes, you’ll have to check and replace it to make sure that the compressor works as intended.

For those who have trouble with the obligation of maintenance, an oil-free air-compressor like the Porter-Cable PXCMF220VW would be the ideal purchase.

They’re lighter and require far less maintenance because there isn’t any oil to check or change. They do this by modifying the lubrication that moves the pistons inside.
Oil-free air-compressors use a pre-lubricated piston, usually coated in Teflon or a similar material, that maintains the surface of the piston even without routine checks. This also allows manufacturers to reduce the number of moving parts inside an oil-free compressor, so they tend to cost less.

The downside is that an oil-free air-compressor also tends to deliver less power than the oil-lubricated option. If you’re particular about noise, it also helps to know that oil-free models are likely to generate far more noise.

Build

There are a few good reasons to inspect an air-compressor for proper build before settling on a purchase. The first is to make sure that there aren’t any leaks that could dampen its efficiency in delivering pressure to your tools. The second is to guarantee that it won’t break down and conk out too soon after you bring it home.

The last is to minimize the risk of accidents. Built-up air pressure can be a very hazardous thing. And if it’s contained in a tank that isn’t reinforced or secure, then you put yourself in very real danger.

Fortunately, most of the air-compressors you’ll find take build quality into careful consideration. But that doesn’t mean they all offer the same level of security. Models that use cast iron – like the Industrial Air IL1682066 – are more likely to withstand wear, tear, and rust. And those that incorporate a secure, stable frame with anti-vibration legs can help maintain your compressor in place even during demanding use.

Portability

At just 20-gallons, one of the benefits of this air-compressor size is that it lets you pull your machine around to bring it to various areas of your home or job site. But just because all of the choices on our list are 20-gallon picks, doesn’t mean they’re all that easy to bring around.

For instance, the Northstar model comes in at a whopping 205 pounds. So even with its wheels and handle, it might be a challenge to pull it around. The Industrial Air IT20ASME on the other hand, weighs modest 60 pounds. But without wheels, you’d have to carry it around via its welded handles.

If you’re interested in something that will practically follow you around, something like the Briggs & Stratton 074064-00 might be a better fit. Large wheels, a reinforced frame, and great traction on a variety of terrain can make an air-compressor a breeze to keep in tow.

Ease of Use

No one wants an air-compressor that demands you to hack your mental bandwidth in two to monitor its status while you work on your job. So, an efficiently designed compressor that maximizes ease of use should be your top-priority.

Models like the DeWalt maximize ease of use by giving you an easy access control panel that features everything you need to see and adjust. Similar models that place all of the controls and gauges in a single, easy-to-view spaces should prevent you from having to walk around to make adjustments or to see pressure levels.

Drainage valves can also weigh down or improve the convenience of a model. Some choices will have oddly positioned drainage ports that require you to tilt the tank over to get all the condensate out. The problem with these designs is that they may cause water damage inside over time, especially if you’re unable to fully drain after each use.

Conclusion

Whether you’re interested in becoming your own at-home DIY expert, or if you’re looking for a brand-new piece of equipment for your small workshop, a 20-gallon air-compressor can be a great investment. But because they come in a wide array, it pays to know your options before making a purchase.

Our top pick for the best 20-gallon air-compressor would have to be the DeWalt DXCMPA1982054 that just shines with efficiency, convenience, and overall great value despite its higher price tag. But don’t just take our word for it.
