Buying Guide

Best Quiet Air CompressorsYou may be thinking that your home, office, or work site could benefit from a silent air compressor. There’s a lot of range in air compressor noise levels. Some sound like a quiet hum, whereas others are as loud as a vacuum cleaner. Quiet air compressors operate at a noise level that is around that of typical speech, so they won’t drown out your conversations and can operate in homes and offices without too much disruption. Here, we’ll tell you all you need to know before you start looking for a silent air compressor, as well as the brands you can trust.

What Make An Air Compressor Quiet?

There is no exact definition for air compressors that are quiet, but models labelled “quiet” do share some common characteristics. Most of these compressors have noise levels lower than 65 decibels, which is around the noise level of a two-person conversation. That means that they are designed so that you can keep on talking even when they’re running.

Those low noise compressors are meant to run indoors, such as in offices or construction sites in apartment buildings,and almost all of them feature electric motors instead of gas, which means they emit no fumes.

About dBA Measurement and Decibel Rating

Best Quiet Air CompressorsHow exactly do you measure how loud an air compressor is? The most common way is with its decibel rating. Sound travels in waves through the air, and these waves have different forces depending on their amplitude. The decibel rating measures the force of these waves, which tells you how loud a sound is.

Typical speech is around 65 decibels, whereas a whisper is around 15 decibels. As the decibel rating increases, so does the risk to your hearing. Once you get to noise levels near 100 decibels, hearing damage can take place in just over 10 minutes. Traditional air compressors can have noise levels of around 90 decibels. That means they can produce hearing damage in less than an hour. Quiet air compressors, by contrast, are able to operate between 55 and 72 decibels. This means they are well within the safe range of noise levels for the human ear.

Who Should Buy A Quiet Compressor?

Traditional air compressors can get the job done for many people. But sometimes you need something that offers full performance while protecting your ear drums. A air compressor that runs on lower DB that normal compressors are perfect for those who need a device that can run indoors without having to worry about noise. They are perfect for offices, homes, or work sites. They also tend to be more portable than traditional air compressors. This makes them an excellent option for those who need a device that they can take with them to job sites.

They are excellent for construction sites where you don’t want to cause too much noise, such as in apartment buildings. They also allow you to communicate with those around you, making any job site safer. They can also protect your hearing. Traditional air compressors can get as loud as a lawnmower. Without ear protection, noise levels this high can lead to long-term hearing damage if you are exposed for extended periods. A quieter unit is great for those that need a device that will run frequently but don’t want to worry about ear protection. With the best low noise air compressors, you can carry on a conversation while it runs without having to resort to shouting.

How Are Silent Air Compressors Different From Other Air Compressors?

How Are Silent Air Compressors Different From Other Air Compressors?These quiet models are designed to reduce the amount of noise produced by the device as it operates so that they can be used indoors. Many other air compressors are designed to be used outside, and have little to no materials blocking sound. This means they can get as loud as lawnmowers, and can cause hearing problems with extended exposure.

Where The Noise In An Air Compressor Comes From

The noise in an air compressor is caused by a lot of different factors. One of the major ones is friction. When parts in an air compressor move, they make contact with one another, causing friction. This, in turn, leads to noise production. Traditional air compressors tend to have more moving parts, leading to more noise.

Many traditional air compressors are manufactured with essentially no sonic insulation. That means there’s nothing between you and the loud noise that the motor makes.

How do you quiet an air compressor, then? Manufactures use a variety of materials to reduce the sound through insulation.

To limit noise, makers of quiet air compressors also use materials such as rubber to reduce vibrations that can cause noise. They also make all of the motors electric, which significantly reduces noise levels. Additionally, they use thicker metals for tanks, which reduces the sound coming from the pumps. They may also use other insulating materials to further block sound waves.

Important Things To Keep In Mind When Buying A Silent Air Compressor

Important Things To Keep In Mind When Buying A Silent Air CompressorThere are a lot of good silent air compressors out there, and some are better at certain things than others. Here are some factors you should keep in mind when buying a silent air compressor.

dBA Rating

This is probably the most important number for buyers of a silent air compressor. The dBA rating tells you how loud the device is as it operates. The devices reviewed here range from 56 decibels to 71.5 decibels. That’s the difference between hearing a soft-spoken voice and someone speaking just a bit too loud. Keep in mind that many traditional air compressors operate around 80 to 90 decibels.

If you need a silent air compressor that can be used in an office or small indoor space, you’ll likely want a decibel rating around 60. If you are working on a construction site, but still want something that isn’t too loud, an air compressor with a decibel rating of around 71.5 will produce a comfortable level of sound that will still allow you to carry on with your conversations.

The dBA rating will vary depending on what setting you are running the air compressor, as well as the acoustics of the room you use the device in.

Tank Size

The size of the tank impacts how long a tool can run before the compressor has to turn back on. Devices with smaller tanks will also tend to produce less pressure- although this is not always true. Since they have less volume for compressed air, they won’t be able to power some tools for long. Smaller tanks, however, mean that the device will be more portable.

If you need an air compressor that can power your tools for long periods, then consider one with a larger volume tank: 8 or 10 gallons. If you only need to use tools that use short bursts of air, such as nail guns, an air compressor with a volume of just 1 or 2 gallons will do.

In addition, take note if the device has one or two tanks. Two-tank devices tend to be a bit quieter, as they can produce pressurized air with fewer revolutions of the piston. Fewer revolutions means less noise. However, this comes with the trade-off of more weight, making these devices a bit less portable.

PSI And SCFM

PSI, or pounds per square inch, tells you how much pressure the air compressor produces inside the tank. SCFM, or square cubic feet per minute, tells you how much air is flowing out of the air compressor. You should pay attention to both numbers when you are purchasing a silent air compressor.

SCFM is important for matching tools to your air compressor. Certain tools will have SCFM requirements, meaning they need a certain amount of air to operate. Always check that the air compressor you are considering buying will be able to deliver enough air to power all of your tools.

PSI is an indication of how well the device’s motor can compress air. Many air compressors operate at around 90 PSI, which is usually enough for most tools you would use around the house. Some air compressors, however, can reach a PSI of up to 200, which allows them to power more specialized tools. Most homeowner won’t need this much power, but some contractors might for particular tools or jobs.

Always make sure you check the PSI and SCFM of the air compressor before you buy it so that you get a device that is compatible with your tools.

Power Source

Best Quiet Air Compressor GuideWhen you’re looking for a silent air compressor, it is crucial that you check the power source. This will affect how loud the device is. There are two main varieties of air compressor: electric and gas powered air compressors.

Gas motors, relying on combustion, tend to be significantly louder than electric motors. That makes them unsuitable for indoor use. Additionally, they emit fumes, which means they can only be used in areas with good ventilation.

Nearly every silent air compressor will be powered by an electric motor. Without any combustion, they operate with much less noise. They also emit no fumes, meaning they are safe to use indoors. You can run your electric quiet air compressor in your garage without any worries.

However, not all electric motors are the same. They may have different voltage requirements. Many will run when plugged into a standard household outlet, with voltage around 120V. Some, however, may need an outlet that can provide 240V. Make sure your outlets are compatible with the air compressor you intend to buy.

Available Accessories

A quiet air compressor may also require other gear and accessories. Before buying yours, check if it is compatible with your tools and accessories. The connectors may vary by brand. The coupler you will need to connect a tool may also vary, so make sure you have all of the ones you need.

The hosing that you’ll require will depend on how much length you need on your worksite. Make sure you have the proper hose when you buy your air compressor.

Also, see what is included with the air compressor, so that you’ll have everything you need to get started once it arrives. This may include hosing, outlet connectors, and anything else you need to connect your devices to the air compressor.

In addition, make sure that you have all the tools you need for whatever jobs you have in mind. The perfect air compressor won’t do you any good if you don’t have the nail gun you need. Invest in quality tools so that you can make the most of your silent air compressor.

Different Types To Choose From

Best Quiet Air CompressorsThere are a few different types of air compressor that you should look out for. Some tend to be quieter than others, which may factor in to which is best for you.

Piston Pump

Piston pump air compressors are the most common type, and the one that will most commonly be used when you need a portable device with a compact design. Like the pistons in car engines, they move up and down, capturing air. All piston pump air compressors are not made the same, however. There are two main types: single-piston and dual-piston.

Dual-piston air compressors tend to be quieter because they can move the air into the tanks with fewer rotations. By rotating less, they are able to produce less noise. This also makes them more efficient and keeps the air cooler than in single-piston air compressors. Most of the air compressors reviewed here are dual-piston pumps, part of the reason they are all so quiet and efficient.

Rotary Screw Air Compressors

These devices are much quieter than piston air compressors, but tend to be much more expensive, and are often used more for industrial applications than for home or offices.

There are two main types of rotary air compressors: oil and oil-free compressors. The oil-based versions are less portable but require less maintenance. Oil-free devices tend to be more expensive, and they often cost more money to maintain.

Whether oil-injected or oil-free, rotary screw air compressors tend to be some of the quietest compressors you can buy. This makes them perfect for workplaces or worksites where you need to carry on conversations while the device is running.

Scroll Air Compressors

These tend to be the most expensive air compressors, but they offer the best performance and produce the least noise of any air compressor. They are designed to run all day, so they are great for any industrial application where continuous use is needed.

Scroll air compressors are not portable, so if you need a device that you can take with you to various job sites, then you will want to choose a piston model. Few homeowners or contractors will require the level of performance offered by scroll air compressors.
