Terms to Know for Air Compressors
- Power Output: The airflow of an air compressor is measured in CFM (cubic feet per minute), which measures the amount of air a compressor can measure in one minute. Since many pneumatic tools require 90 psi (pounds per square inch) to operate, many air compressors are measured in how much CFM they can provide at 90 psi.
Best Overall
Good For: Homeowners who frequently use an air compressor and want a powerful, reliable model.
What Are People Saying About the Makita MAC2400 Big Bore Air Compressor?
Satisfied customers said that this product had quality components. Others mentioned having owned it for more than a decade without experiencing any issues. On the other hand, a handful of customers cited issues with replacement parts and customer support, and others felt it was too heavy to operate for those with back issues.
“This is a great quality compressor. There are a lot of nice features. The couplers are quick-connect and come already installed. The gauges are large and easy to read right on the front of the panel, and all the most delicate parts are firmly mounted on rubber isolation grommets within the ‘roll cage’ frame. It’s easy to fill and change the oil. The sight glass is easy to see. The rubber feet are sturdy and likely to stay attached long term.” — H D via Amazon
“This is a great compressor, well made and more silent than others. All the other reviews say the same but they don’t mention that it’s very heavy. If you have problems like me, this is not for you. Wheels and a handle would make a difference.” — Jesus Puente via Amazon
Best Starter Option
Good For: Homeowners who need a straightforward compressor for small- or medium-PSI tools like brad nailers.
What Are People Saying About the Craftsman CMEC6150K Air Compressor?
Satisfied customers said that the product was easy to maneuver. Some also praised this item for its varied attachment options. Those who weren’t pleased with their purchase said that the pressure buildup was disappointing. A few mentioned they also felt it was too loud.
“The best portable air compressor that I have owned in the last 30 years. Quickly pumps the air up to 120 PSI, and held the pressure for two nights with no loss. The tank and line pressure gauges are accurate and easy to read when doing some construction with air tools and the tank was able to keep up with the demand and had a very quick recovery. Recommended for those who want to use in a small home shop.” — JPKirkpatrick via Amazon
“…I wasn’t quite prepared for how loud it is when filling. I even preplanned for the noise by plugging it in outside my garage and running the more-than-long-enough hose in the side door to my workbench. I’m not sure the neighbors will appreciate the very loud noise from this machine.” — Kidder via Amazon
Best Pressure
Good For: Those looking for a high-pressure compressor that can handle large tools.
What Are People Saying About the DEWALT DWFP55126 Pancake Air Compressor?
Customers were pleased with the performance and price of this product. Several reviews also mentioned how portable the air compressor was with its sturdy handle and small size. Dissatisfied customers were frustrated with the lack of customer support from DEWALT, and others said it struggled to remain at the set PSI level.
“This air compressor is absolutely awesome. So very lightweight, easy to carry. Doesn’t take up much space when storing the compressor. Multiple connectors, high pressure rating. So easy to use. The instructions were easy read and understand. This compressor can be used in so many ways. Just remember when purchasing it doesn’t come with any hose or attachments. Great quality at a modest price.” — David Stockham via Amazon
“…When the pressure is set to any level lower than about 100 psi, the pressure quickly creeps up when not being used. When set to say, 40 PSI attached to a blow gun, the initial burst is strong, but the pressure immediately falls to around 20 PSI and stays there until demand is off. The pressure returns to 40 PSI. This is totally bad for tasks such as spraying finishes.” —Coatside Kirk via Amazon
Easiest To Maintain
Good For: Customers looking for a straightforward compressor with minimal setup and maintenance.
What Are People Saying About the PORTER-CABLE Oil-Free Air Compressor?
Customers said that this air compressor performed well, providing excellent value for the price. Others said that the included accessories covered most household and automotive needs. The low-rated reviews were from customers who were frustrated with the confusing manual and leaking susceptibility.
“This compressor worked well for my needs and wasn’t undersized. It handled spraying texture excellently and performed very well. If you don’t need a large portable compressor then this one will work for you and handle any small to medium job. It was light and very portable and never had any difficulties and doing the job I got it for.” — Anthony Fusco via Amazon
“…The new handle and power cord hanger are a big improvement, but there is a banging sound when the compressor is running. Also, there is a slow leak someplace, so if I do not use it for a while there is little pressure left.” — Amazon Customer via Amazon
Quietest Compressor
Good For: DIYers looking for a quiet compressor that has a heavy-duty tank.
What Are People Saying About the California Air Tools Steel Tank Air Compressor?
Happy customers said that the product offered quiet operation and good value for the money. They noted that the machine reliability provided compressed air for light- and medium-scale jobs. Unsatisfied customers mentioned experiences with leaks and burning smells, and some said that the customer support team was unhelpful.
“I’ve had refrigerators louder than this air compressor. It’s not the fastest compressor, but it’s worth it to have such a quiet running machine. I can use it without waking up the whole house.” — Adam North via Amazon
“I received the air compressor in good condition. I read the tiny print manual and followed the set-up procedure. I turned it on and it filled the tank and blew out the relief valve. I filled it again and stopped it before another blow out. I put one of my tools on a line and plugged it into the unit. It would not stop leaking around the fitting.” — Russell via Amazon
Best Cordless
Good for: Customers looking for a small, cordless compressor they can bring anywhere.
What Are People Saying About the RYOBI 18V ONE+ Air Compressor?
Our research showed that customers who gave this product a positive review were impressed with its compact, versatile design and its quick air buildup. Others commented on how easy it was to use. However, there were others who claimed this air compressor lacked power even for small jobs, while others claimed it was overly loud.
“….It fills its small tank super fast, and when it’s full, it fills my tires just as fast as my old big tank. When it’s depleted, you have to give it a minute, though. So overall, if you have to fill very deflated tires, it will be longer than shop air but faster than most portable compressors. Much faster. For my purposes, it’s perfection.” — Robb Ryniak via Amazon
“As I expected, this compressor can’t really run tools. All I wanted was something that I could use to blow off tools and vac filters at the end of a work day and this barely does that. I basically use it for about five-to-eight seconds and the tank is depleted, go and do something else, then come back and repeat the cycle.” — Michael Byrnes via Amazon
Best for Cars
Good for: Those looking for a compact compressor for adding air to your tires, even when you’re away from home.
What Are People Saying About the AstroAI Portable Air Compressor?
We noted that several customers who gave this compressor a positive review liked that it was easy to use, noting it required almost no set up. Others were impressed at how powerful it was given its compact size, as well as its durability and well-crafted construction. On the other hand, there were a few negative reviews that pointed to this compressor having inaccurate readings, and others that said the power cord broke easily.
“I’ll be honest, I didn’t have high expectations for an inexpensive 12V tire inflator, but this little thing turns out to punch way above its weight in terms of how well it works given the size and price. In fact, I was surprised by how small it is—I didn’t realize that it’s not much bigger than the size of a shoe. It’s quick and easy to use, a totally straightforward piece of machinery that lets you set the pressure level you’re looking for, flip a switch, and get what you want.” — JOSHUA via Amazon
“We actually really like the convenience of this inflator, but we had some issues right out of the box. 1. The reading is not accurate (off by 1-3 pounds) so take that into consideration. 2. The inflator is supposed to stop inflating when it gets to the set PSI. However, this only worked about half the time… I did contact the manufacturer, but they didn’t really give me a legitimate answer for the lack of accuracy, and they didn’t address the inflator not turning off when it should at all. I guess it does the job, just disappointed with these issues.” — Cindita M. via Amazon
What To Know Before Buying an Air Compressor
There are several important thing you should keep in mind before deciding on what air compressor is best for your needs. Start off by determining if you prefer electric or gas and how much airflow and pressure you need based on what types of tasks you will be using the compressor for.
From there, you can look at factors such as the required maintenance, size and portability, tank size, and noise level to help you narrow down your choices Read our guide below to learn about some of the most important factors to consider before choosing an air compressor.
What type of fuel do air compressors use?
Air compressors are powered by electricity or gas. Gas air compressors are large, stationary units that are meant for commercial use. Electric air compressors are portable if they’re meant for household tasks or immobile if they stay in a workshop. Both types are useful in supplying air to a variety of power tools and other pneumatic tools.
What is the standard maintenance of an air compressor?
Compressors are either oil-lubricated or oil-free. Oil compressors require the occasional refill so that the cylinders stay lubricated. Oil-free compressors have Teflon-coated cylinders that don’t require lubrication. While you don’t have to worry about maintenance with an oil-free compressor, the Teflon coating eventually wears off, requiring you to buy a new compressor.
How is speed measured in a compressor’s motor?
The speed at which the motor works is measured in horsepower. The higher the horsepower, the faster the motor can refill the compressor’s tank.
How is airflow measured in air compressors?
Cubic feet per minute (CFM) and standard cubic feet per minute (SCFM) are used to measure airflow. SCFM is measured in a controlled environment at 68 degrees Fahrenheit, 14.7 pounds per square inch (psi), and 36% humidity, while CFM is only measured at 90 psi. Generally speaking, SCFM measures airflow in perfect conditions, while CFM measures airflow in realistic conditions. If you’re planning on using attachments or compressor tools, such as grinders and nailers, you’ll want to pay attention to airflow because the air compressor has to match or exceed the CFM or SCFM rating of the tools.
In the video below, This Old House‘s Kevin O’Connor and Tom Silva break down the various types of air compressors available and how to measure the SCFM against the PSI.
How do you determine the pressure level of an air compressor?
PSI measures the amount of pressure placed on a square inch of space. Air compressors have a maximum psi they can deliver, with even the smallest and most affordable models being able to deliver at least 100 psi. Like with CFM and SCFM, you’ll need the air compressor’s maximum psi to be equal to or higher than the item you’re using it on. For example, if your car tires have to be pumped up to 35 psi, your air compressor must be able to deliver at least 35 psi.
What is a standard tank size for an air compressor?
A compressor with a larger tank holds more air, allowing you to go longer before needing a refill. Most household air compressors have tanks between four and eight gallons. Portable air compressors typically have smaller tanks than this.
How do you measure sound in an air compressor?
When air compressors are on, they have a sound level between 40 to 90 decibels. If you’re sensitive to sound, consider purchasing a compressor that has a decibel level around 60 decibels—the sound of an average conversation—or less. A compressor with a 60-decibel sound level is considered ultra-quiet.
How To Use an Air Compressor
While not all air compressors are exactly the same, they all operate in similar ways. Follow the steps below to ensure you’re properly using your new air compressor.
- Position the compressor and check the oil: The first thing you’ll need to do is to position the air compressor on a flat, stable surface. From there, connect the power cord to a grounded outlet (avoid extension cords for anything other than light-duty models) and check the oil to ensure you have enough to complete the project. Note that some light-duty and battery-powered models will not have oil.
- Check the drain valve: Next, check the drain valve at the bottom of the air tank to make sure it is fully tight. Use an adjustable wrench to tighten the valve if it is loose.
- Set up the air tank and prep the psi: Next, you should turn on the power switch and let the air tank run for approximately 1-2 minutes. Ensure the air pressure gauge switches off when it reaches the top pressure capacity. After it is warmed up, you can set the psi to your desired amount on the air control valve. Check your tool to see what psi level you should set. For example, most pneumatic tools run on 90 psi.
- Connect the hose: Once your psi is set, you’ll want to connect the air hose to the portable compressor. Make sure the hose is long enough to reach your service area. Use a wrench to tighten the hose if it is not fully secured.
Frequently Asked Questions About Air Compressors
What are some household tasks I can use an air compressor for?
You can use an air compressor for a variety of tasks, including:
- Pumping air into car tires or as a general tire inflator
- Power washing decks or walkways
- Spray painting decks or pieces of furniture
- Inflating air mattresses or pool toys
- Other DIY projects that require high levels of air pressure
How often will I need to change the oil in my air compressor?
Read your product’s user manual to see if it specifies how often you need to change the oil. If it doesn’t, a general rule of thumb is to change the oil every 200 to 300 hours of use for conventional motor oil and every 1,000 hours for synthetic oil.
Can I leave air in my compressor?
You shouldn’t leave air in your compressor. If you do, the water that was compressed out of the air will sit at the bottom of the tank. This water will corrode the tank and shorten the compressor’s life. Instead of leaving air in your compressor, use the drain valve to release the air after every use.
What is a good size air compressor for a home garage?
A good size air compressor for a home garage ranges from as small as two gallons to as large as 20 gallons, which is suitable for hobbyists with light-duty needs. For commercial-level or heavy-duty jobs, you’ll want to look for an air compressor that’s closer to 60 to 80 gallons.
