Quietest Air Compressor
There’s no lack of noise in the world around us, and silence has become a privilege not many can afford. Almost everything around us produces some level of sound, and we’ve more or less learned to live with it. However, that doesn’t mean we’ve learned to like it. Whenever we get an opportunity to choose a noiseless environment over a noisy one, we’ll choose the noiseless one every time.
When it comes to purchasing a tool or product, not many of us can honestly say that we consider how much sound it produces before purchasing it. One would imagine that the size of the machine is more important than any noise considerations. And yet, here we are, talking about the quietest air compressors, because noisy air compressor units always end up becoming an annoyance after using them for a while.
The fact of the matter is that concentration is the name of the game when we’re working with tools or operating machinery. No one wants to work in an environment where their eardrums are being pierced while using an air compressor. That’s a health and occupational hazard we can do without. This is why we’ve compiled a list of the quietest air compressors you can purchase in 2021 to meet your needs without making your ears miserable.
First, we will talk about the whats, the whys, and the hows of an air compressor, and figure out why they produce noise in the first place. We will also outline the key specifications of the quietest air compressors and what terms and numbers you should be looking out for when buying an air compressor unit. Then we will list our top picks for the quietest air compressors of the year along with a relevant description and key features of each one. Read on to find out everything you need to know about noiseless air compressors, all in one guide.
How Quiet is Quiet?
One thing that is worth mentioning is that noise and silence are relative terms. An air compressor isn’t just inherently quiet, it is quiet relative to the noise in the environment. A bell that you find particularly loud might seem practically silent in an industrial setting, and even crickets aren’t soundless in absolute silence. Therefore, what one may define as quiet may not be quiet at all for someone else. To work around this, we use standardized measures of sound such as decibels (dB) to talk about how much sound a particular machine produces. 0 dB is the quietest sound that a healthy human can hear. For reference, a normal human conversation has a sound intensity of 60 dB. Anything more than that will drown out your voice. Long-term exposure to sounds above 85 dB are generally considered harmful for human ears. A noise level below 80 dB is thought to be quiet compared to our surroundings, and that is that threshold used when terming the quietest air compressors. The sound levels of the air compressors on this list are all below 80 dB, which is a feat compared to their counterparts on the market.
The ABCs of Air Compressors
Air compressors are a staple of many households, workshops, and industrial settings. They are necessary for the operation of many pneumatic or air-powered tools. Nail guns, paint sprayers, stapling guns, drills, wrenches, buffers are just a few of many tools that can be paired with air compressors to complete a variety of jobs in your house, garage, workshop, or industries like construction and manufacturing.
How does an air compressor basically work? Firstly, ore and more air is forced into a storage tank through the action of the motor. This increases the pressure of the gas inside the chamber and, depending upon the specifications of the air compressor unit, generates enough energy to power large industrial equipment or household appliances. A hose connects the air compressor to the air tools and compressed air travels to the tool by way of it, effectively powering it.
Why Use an Air Compressor
You may be wondering why you should purchase an air compressor in the first place. Some people tend to think that such machines are only meant to be used in industrial settings, and as such, they miss out on the benefits of using an air compressor. For one, these machines reduce the cost of completing jobs involving tools, making them cost-efficient. One may assume that two machines, an air compressor and an air tool, is more expensive than an electric or battery powered tool. However, the former is more cost-efficient. The combined cost of an air compressor and pneumatic nail gun is actually several hundred dollars less than the cost of an electric nail gun. On top of that, pneumatic tools are more lightweight and easy to move compared to their battery powered counterparts. Therefore, they are more versatile and user-friendly, especially when used for odd jobs around the house. Air compressors can also be used to power tools for jobs like cleaning, using an air blower, and auto repair, using an air ratchet tool. The product is also useful for people who want to connect it to a spray gun for painting, leading to a more even and smoother paint job, while also saving time. As such, there are no restrictive limits to the uses of an air compressor.
Noise by Air Compressor Type
There are 3 basic types of air compressors, and each works with a different power source. These sources are electricity, gasoline, or diesel. To use air compressors with electric engines, you need to connect them to an electricity source. These types of machines operate using induction motors and are best for personal use. Air compressors with gasoline or diesel engines normally have bigger tanks and are used for mid-range or high-end jobs. However, as their name states, they require fuel to operate.
Beyond that, there is also another classification. The way that various air compressors compress air also determine how much noise is produced. Reciprocating compressors are the most common and least expensive, and they use pistons to rapidly pump air in. If a reciprocating compressor is powered by gas, it is bound to be loud. Electrical reciprocating compressors are much quieter, but still have the sound from the pistons to content with. Having a machine with low RPM will reduce how hard the pistons are working and dampen noise. Additionally, having a thicker cast-iron cylinder around the unit will also lessen noise produced through vibrations.
The next type is a rotary screw compressor, which is much more expensive, but also much more noiseless. These include large screws that are continuously spinning and forcing air inside the container. The components in this type of air compressor do not produce vibrations and only limited noise since the screws aren’t actually touching. They also work at lower temperatures and are safer to use with pneumatic tools. Lastly, we have scroll compressors which are the most expensive and quietest air compressors. They operate using one stationary and one mobile spiral element moving up and down a cylinder, forcing air inside. This type of compressor is exclusively found in commercial factories, where they run continuously.
CFM and PSI
The CFM (cubic feet per meter) and PSI/psi (pounds per square inch) are both ratings that you need to look out for when searching for the quietest air compressor. The CFM rating tells us how much air the air compressor is able to supply (its output rate) when it’s operational. The psi count is a measure of how much force or pressure is applied per square inch, and is equivalent to the power of the compressed air. To simplify it, the CFM is the amount of air supplied, while the psi is the power of air supplied. These two metrics are interrelated. Air compressors specifications will always include these two ratings as they are a testament to the functionality of the machine.
The higher the CFM rating at a standard psi count (usually 90 psi), the better the air compressor. More versatile air compressors are able to deliver different CFM ratings at different psi counts, allowing them to be used for a range of jobs in multiple settings. To give you an idea, a 3.0 CFM is ideal for light tools. 4.0 to 5.0 CFM is the sweet spot for operating different kinds of tools in a workshop, and a CFM for 5.0 is required to power industrial appliances. It is important to find the quietest air compressor that gives the highest CFM airflow required for your tools at a certain psi count. Too high of a CFM rating means extra unwanted noise, and we want to avoid that. This will save you the headache of trying to work with a noisy air compressor down the line.
To Oil or Not to Oil
Friction and noise go hand in hand. If you think of the various moving parts of an air compressor constantly grinding and rubbing against each other, you can almost hear the grating sound they produce, not to mention the incessant vibrations. We present you: oil. Lubrication goes a long way in smoothening the function of an air compressor and protecting the components from wear and tear. Oil lessens the unwanted friction in the machine and ensures that all the parts keep working smoothly. This reduces the amount of sound the air compressor produces while working.
Oil lubricated machines are almost always quieter than machines that aren’t oil lubricated. However, there’s a catch. Introducing oil into the system means regular maintenance, not to mention frequent oil top-ups. You also need to be wary of oil leaks since oil dripping into the air compressor’s storage tank will affect the performance of the product. All this checking and cleaning might not be what you signed up for when you searched for the quietest air compressor. Therefore, we would recommend avoiding oil lubricated machines altogether to save yourself the trouble.
Bigger and Better
The capacity of an air compressor’s storage tank, measured in gallons, is one of its most important attributes. The motor of an air compressor works by filling the tank with air, which is then compressed and supplied to a tool through a hose. There isn’t a continuous supply of air, as one might think. If there isn’t sufficient air stored inside the tank, the pressure and air speed will slowly decrease until you’ll have to pause work so that the motor can turn on and refill the tank. This can take any amount of time, wasting precious minutes. An air compressor with a large storage tank will be able to power a tool for longer in one go, or even power multiple tools at the same time. This feature is especially important when operating tools like paint sprayers. However, one needs to consider that a large storage tank equals a large air compressor that takes up considerable space and is difficult to lug around. Consumers need to select a unit that doesn’t compromise on the tank capacity while retaining compactness and mobility.
Now that we’ve got the basics out of the way, we can get into the quietest air compressors you can buy. Here are our top picks for the quietest air compressors with the best performance and efficiency. This list is not exhaustive, but it does cover most of the best options available in 2021.
Our list of handpicked silent air compressors kicks off with a leading competitor, the California Air Tools 8010 Ultra Quiet Air Compressor.

Those who are familiar with the quietest air compressors available for purchase are bound to be well-acquainted with Eagle Silent Series as well. The name of the Eagle EA-6500 air compressor includes the word “silent” in it, and it definitely lives up to it. The air compressor unit powered by an electric motor has a decibel rating of only 53 dB, which makes it one of the most noiseless air compressors present on this list. Keep in mind that human conversation has a sound level of 60 dB, and this is significantly less than that. The 20 gallon air compressor weighs in at 132 pounds and has a height of 45.96”, which makes it one of the larger models on this list. This obviously reduces its mobility, but not by much since it has a roll cage design, anti-vibration feet, and never-flat wheels that can scale rugged terrain and allow for the machine to be easily transported. The EA-6500 also makes up for the bulkiness with its exceptional power and performance. The manufacturers cite the low RPM of the machine’s motor as the reason for its limited sound output. We wouldn’t begrudge you doubting the air compressor’s power since it has a low RPM, because we thought the same. However, there is no cause for concern. The Eagle Silent Series 2-HP 20-Gallon Air Compressor has a whopping CFM of 60 at 90 psi and a CFM of 7.9 at 40 psi, which is incredible. As for the motor, it has a running 2 HP and peak 2.5 HP rating. The double piston pump system is oil-free and requires no maintenance.
