Best Quiet Air Compressors Buying Guide
Now you’ve seen a few of the best available offerings that are currently on the market when it comes to quiet air compressors.
If you’re still not convinced, however, or if you need to be pointed in the right direction of which factors you should consider, and which you should prioritize in order to find the perfect air compressor that’s quiet enough for your needs.
First, we wanted to remind you about some of the great benefits that are associated with having your very own air compressor.
After that, we’ll then get straight into what you should look out for when making your decision about which compressor you’re going to opt for.
What Are The Benefits of Having Quiet Air Compressor?
Although we hinted at a couple in the introduction to this article, there are a number of different advantages to having your own air compressor.
Provides power for your hobbies and DIY projects
If you enjoy carpentry, crafts, or DIY of any kind, there are plenty of tools that can be powered by an air compressor which will make it much easier for you to complete various parts of the project more efficiently, making something like a quiet airbrush compressor a convenient tool to have.
Even cleaning out the dust from rails and hinges of your garage door opener becomes super easy.
Turns big jobs into smaller jobs
Jobs around the home, like spray painting the walls or the fence in your backyard, can be made into light work with the use of an air compressor.
In fact, after buying one of these tools there’ll soon be nothing left that’s untouched by paint, as covering cabinets, furniture, and even smaller pieces will become a breeze.
There’ll be no more need to hire a professional painter every time you notice a patch that’s starting to show peeling, as you’ll find it easy enough to complete these jobs yourself, which will be a lot cheaper than paying a professional to do the work for you.
Versatile use means it can help you with a number of different jobs
The fact that air compressors can be used for so many different applications makes them a hugely versatile tool that any home DIY enthusiast or hobbyist will greatly benefit from.
Some examples of what your air compressor can do include the following examples:
- To power tools like drills, hammers, and compactors on construction sites and in industrial settings.
- They can be used in manufacturing to power rotary screw equipment to ensure that products are sealed tightly and free from contaminants.
- Air compressors can power tractors, sprayers, pumps, crop conveyors, and a number of other pieces of equipment that are used for farming and agricultural purposes.
- Used to heat or cool vehicle engines as well as pumping air into the brakes of bigger trucks.
- You can run your pressure washer using your air compressor which will pump high pressure water through the washer to effectively clean areas like concrete surfaces, hard floors, and brickwork to remove stains.
Plus a whole lot more!
The combination of versatile use and durability means that air compressors work out as being pretty cost-effective when you consider the whole picture.
Often constructed using high-quality materials, the majority of air compressors will provide long-lasting use.
Need to make some DIY repairs? No need to bother calling your regular handyman!
As we mentioned earlier, by making certain jobs easier, having an air compressor will allow you to tackle these by yourself instead of having to hire a professional to do it all for you.
Establishing the intended purpose behind your air compressor will help you choose the right one for you and your needs.
It determines which specifications you should look out for as well as giving you some indication of how noisy the air compressor will be when it’s running.
The reason behind your purchase will also often dictate your budget and how much you’re happy to spend on a new tool.
As a side note, the quieter models do tend to be a little bit more expensive in general compared to air compressors that make more noise.
Speaking of such...
Given the fact that you’ve found your way to this article, we’re guessing that noise level is going to be a big factor in making your decision about which air compressor to get.
It can be tricky to measure noise level, especially when you’re buying online with no way to test out the product before you purchase it, but most products will have a dB rating listed.
The decibel rating will give you an indication of how loud your air compressor will be.
The difference between 30 and 40 dB might not seem like much, but the volume level doubles with every increase of 10, so 50 dB is around 4 times louder than 30 dB, for example.
Another way of gauging how loud an air compressor will be during operation is to check out what other customers have said about the noise volume in the reviews section.
Long term exposure to sounds below 70dBA is unlikely to lead to hearing loss so aim below that. Long or repeated exposure to noise over 85dBA will damage your hearing.
Whenever you’re buying new tools to store at home, you need to think about the space you have to store it in, as this will have to inform your decision about which size you should get.
It’s one of the most obvious factors to consider as it’s one that can make a huge difference.
If you’re someone who is living in a small apartment or if there’s a limited amount of room for storage in your home, you’ll be forced to choose a smaller unit that will be suitable for the available space.
There is a wide range of air compressor sizes to suit a range of applications, with models like a pancake compressor being the best for small spaces as it can be stored on a shelf.
Remember though, that a smaller compressor will only be capable of smaller jobs.
If you have the room and you think you’ll be using your air compressor for more heavy-duty applications, why not opt for a larger model?
You won’t be able to overwork your compressor if you underestimate your needs, so if your budget can accommodate one, investing in a larger air compressor will widen the scope of the future DIY projects you can complete.
Speaking of size, it’s important to think about the size of your air compressor’s tank. The tank capacity is typically given in gallons and will determine how often you’ll need to refill.
You should choose a tank size depending on what you’re planning to use your air compressor for most often.
Less demanding jobs, such as powering tools like a brad nailer, will typically only see short bursts of use, and therefore you won't require a tank that big.
Spray painting, on the other hand, is a larger job that will take a lot more time to complete, meaning you’ll be using your air compressor for a longer period of time. In this case, a larger tank will be beneficial as it means you can go for longer between refilling the tank with paint.
When choosing an air compressor, you’ll need to decide between one that’s run on either electricity or gasoline.
The majority of electric air compressors can be run off a 110-120V standard household current and are ideal for interior DIY work.
Comparably, gas-powered air compressors are a good option for outdoor use where you may have more difficulty finding a reliable source of power to run your air compressor.
They’re also the more portable choice of the two, which is useful for traveling purposes.
Oil-Lubricated vs. Oil-Free
The next important decision to make is whether you’d prefer an oil-lubricated or an oil-free air compressor.
Oil-lubricated compressors tend to last for longer before showing signs of wear and tear as the lubrication prevents the moving parts from becoming damaged.
As you could probably work out from the name, oil-free air compressors are free of any oil. Groundbreaking, we know.
The fact that they’re smaller and more lightweight than oil-lubricated compressors means they don’t require oil and makes them a popular choice.
Frequently Asked Questions
Which air compressor is the quietest?
If you are looking for the best balance of power, price and low noise operation then the California Air Tools 8010 is the quietest air compressor we'd recommend.
How many dB is a quiet air compressor?
It all comes down to power. A low power air compressor will be really quiet but won't be really useable. If you aim around the 60dB noise level mark you'll get a quiet compressor that will still do the job.
Can you get a silent air compressor?
No. The only silent air compressor is one that's switched off. All air compressors will make some noise.
Why are air compressors so loud?
There are actually a few different reasons that contribute to the noise volume produced by air compressors that are in use, but it’s mostly due to the friction created by the vibrations.
The noise level can depend on the model you opt for and how simple or complex its construction is, as when there are more components to move together it does typically tend to result in a louder operating volume, and this also applies to the motor.
Air compressors that are powered by electricity therefore tend to be quieter than gas-powered compressors, as these contain a higher number of moving parts.
How can I make my air compressor quieter?
Even when you buy an air compressor that’s been specifically designed so that it will operate at a quieter noise volume, you may still wish to reduce how loud your air compressor is when it’s running.
Luckily, there are a few ways you can make your air compressor quieter.
This includes the following options:
Put it further away:
If possible, put the compressor further away from you. Get a longer hose and wire the switch near the area you'll be working in. If you soundproof the room that the air compressor is in then it'll be even quieter.
Use rubber to cover certain parts of the air compressor, as this can help to reduce the level of vibration that’s produced which results in quieter operation due to its insulating properties.
This is also useful for absorbing some of the impact from use which helps to keep any echoing to a minimum. Not all rubber coverings will work the same, however, so make sure you choose the right type for your air compressor.
Cover or Change the Ground’s Surface
Due to the vibrations that your air compressor experiences when it’s running, being in contact with hard surfaces can result in loud noises because of the movement.
To combat this, cover the ground on which your air compressor is going to be standing with a rubber mat or choose a location with a different surface to see if this improved the sound. You can also mount the air compressor and/or pump on rubber grommets to reduce noise.
Make a Few Modifications
With some air compressor models, you can modify or change the intake and exhaust systems which can alter the level of noise it produces when it’s in use.
For example, installing an intake silencer will drastically reduce noise volume during operation.
Build a Soundproof Box
If you’re still not happy with how much noise your air compressor is producing, you can construct a containment box that can work to effectively muffle the noise produced by your compressor for a more soundproof effect.
Whether you opt for a design that is simple or complicated, your containment should always be made using fire resistant materials for additional safety. Also, be careful not to restrict the airflow around the air compressor unit, otherwise, you could cause it to overheat.
Something similar to our DIY generator quiet box would work too.
What is the loudest air compressor?
As a general rule, air compressors tend to be louder the bigger in size they are. This is because they’re usually more powerful as they’re designed for more heavy-duty applications.
Whilst there are plenty of models committed to quieter performance, like the examples we’ve listed throughout this article, a lot of air compressors operate at a fairly standard dB rating.
It’s hard to pin-point one single model that’s the loudest air compressor of all, but at the louder end of the spectrum, you’ll find some air compressors that produce up to as much as 90 dB, which is incredibly loud when you remember how decibels are measured.
Can air compressors be dangerous?
It is highly unlikely that there will be safety issues with your air compressor, as long as you use it appropriately and in the correct manner.
Misusing air compressor tools can, of course, result in a higher risk of injury as well as potentially being dangerous for the user.
Some of the dangers associated with air compressors include:
- Air embolism
- Ruptured eardrums
- Ruptured organs
- Dislodged eyeballs
- Temporary hearing loss
Should I drain my air compressor after every use?
Yes, you should definitely drain your air compressor after every time you use it. This is to prevent water pooling in the tank, as this could lead to corrosion or rust, and it could even potentially weaken its structure.
To drain your air compressor, simply release the air with the drain valve open and allow any condensation to drain out of the tank.
It’s also a good idea to leave the tank facing downward while you let it air in order for it to fully dry on the inside.
Buy one of the quiet air compressors reviewed above and your ears will thank you even after longterm use.
