How to Quiet Air Compressor Noise?

Air compressors are devices that help compress air and run a different type of power tools. Whether you are using an electric one or just one that needs oil to starts, they are famous for making loud noise levels.

Of course, air compressors come in for various projects around the house, but the noise is almost unbearable. They produce sounds between the ranges of 70 to 90 decibel.

You may already know that the human ear can only handle around 80 decibels of sound range. Anything above that can cause damages, especially if one is exposed to the sound for a long time.
No wonder why people around are thinking about how to air compressor quieter in the workplace!

Now you have a full summary idea on how to quiet an air compressor? Let’s drive into full depth review. Where we talked more than 5 ways to do this task.

Use a Muffler/Silencer Box:

This is an inexpensive way to deal with this issue. A muffler is often used in motor cars or bikes. It can install on the air intake to reduce the air compressor noise levels by 2 decibels. Some mufflers can cut the noise levels up-to 4 decibels and it’s a bit more expensive.

But considering your hear is at stake here, it’s a small investment that is worth making. You can connect a muffler to one end of an air hose. Then you can connect the other end to the air intake component. You can get a muffler or air compressor silencer box online or from your nearby shop. It will give heavy-duty to making your air compressor quieter than before.

Use Sound Blankets:

Apart from the exhaust and intake, the air compressor’s piston cylinder is one of its common causes of louder noise. Sound blankets can prevent that noise from being echoed or boosted up due to reflection from the walls in your room. You can put sound blankets on the wall, and it will prevent the amplification of sound.

Sound blankets can absorb medium to high-frequency sounds level. So they are pretty handy to quieting air compressors if you place it properly.

Shift the Air-Intake Outside:

Most of the noise comes from the air intake component. To reduce the noise levels, you should use an extended rubber hose. It let the machines suck the air from the free area outside and in turn, consume the noise. You can also use a pipe, it will work like air intake.

Likewise, as you can keep the pipe or hose out, you won’t be hearing the sound as louder as before when working indoors.

Make a Noise Reduction Box:

This is perhaps, the most effective way to deal with the noisy stuff. Means, building a soundproof box for preventing unusual noise, and reduce air compressor’s throat. You can make a DIY sound enclosure for your power generator out of cardboard or foaming substance. And you can use fire-resistant materials like gypsum or hard concrete for creating the noise reduction box.

Noise Reduction Box

The unit of the compressor should be inside the enclosure, and there need to be openings for the exhaust and wires. If the power outlets and hoses are left trapped inside a confined space like the enclosure, there might be accidents.

These are the important materials you’ll need to make your air compressor quieter box:

          • A saw (circular ones are better)
          • Screws
          • A Driller
          • Foam
          • Adhesive spray

Modifying such a soundproof box for your air compressor is an easy way to reduce the noise drastically. If your air tool doesn’t produce earth-shattering noise, to begin with, this box might make the entire sound fall to a minimum.

Use Rubber Grommets:

Rubber has sound level deadening capabilities, and it’s a probable solution. You can find rubber grommets on Amazon from around $2 to $10 or more prices. There are different types and sizes of rubber grommets available in the market so you can get one according to your machines.

Rubber Grommets

If the motor is secured using rubber grommet, you can reduce the noise significantly. The vibration in the engines causes a lot of noise when an air compressors start. As the rubber absorbs the vibrations, it reduces the noise levels to act as an air compressors sound deadening.

Maintain the Air Filters:

Air filters clean the air when the compressor sucks in. So if they don’t work properly and gets dusty, the compression process will get noisy. In that case, before the filters get clogged, it’s good to clean them up.

Therefore, it’s recommended to clean up them at least once every 12 months though this does depend on where you live and its uses. The dusty environment calls for more cleaning.

Use Lubricant for the Parts:

Oil-less air compressors tend to make more noise than others. If you are wondering how to quiet an oilless air compressor, lubrication is your answer. The friction between the different types of parts is the reason behind all the annoying noises. That’s why it is essential to oil and lubricate the components to prevent friction and rust.

Air Compressor Lubrication

Accordingly, lubricating the moving parts with grease can reduce corrosion and make your air compressors more durable. But it is to be noted that too much grease can make the bearings of the machine difficult to move.

Hence, this might damage the engine. So, you should use just the right amount of lubricant.

Buy a Top-Quality Air Compressor:

This is an obvious solution. If you get an air compressor of better quality after checking the decibel (dB) count, there’s a lesser chance of having a headache due to crazy noises. A cheap budget new air compressor will only cost more in the long run with all the parts needing touch-ups and replacements again and again.

Get Professional Help:

It’s always good to let experts help out when you’re confused about what the problem is? And how you make your air compressor quieter? Which actually works!

These easy steps on How to quiet air compressor noise, will surely help make your work fewer boring and protect your ears from any possible harming.

  1. I have a quick question for you. Are vertical tank air compressors better than horizontal tanks? From what I’ve been told the vertical tanks can hold more air. Thank you in advance for your answer.

    • Hey, Claud

      Thanks for getting touch with us through your question.

      anyways, The only main difference between a horizontal and a vertical air compressor is the amount of floor space they take up.
      But, when you are ultimate user then you should consider it with your exact and high requirements. Means, its vary on demands and possibility.
