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.

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.
Air Compressors FAQs
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.
