How to Make an Air Compressor Quiet?

by James Williams

Air compressors are devices that are used to increase the pressure of a gas in any given system by compressing the air inside it. Almost every home owns an air compressor these days, and a majority of users have one common complaint: their compressors are too noisy.

If this sounds like you, then you have come to the right place because, in today's article, we will be walking you through some steps on how to make an air compressor quiet.

What Causes an Air Compressor to Be Noisy?

Before we start, let us take a look at the cause behind today's problem so that you will have a clearer concept of what you should be doing and why you should be doing it.

Vibration Due to Assembly

A lot of times, the main reason why your air compressor is making a lot of noise is due to incorrect assembly of the device, so take a look into that as well.

This could be due to some minor parts of the equipment being loose or getting misplaced and also require some looking into.

Product Material

Cheaper air compressors are usually made out of thin metal, and due to this, the materials tend to make a lot of noise because it causes them, and consequently the compressor itself, to vibrate more.

To prevent this from happening, contemplate saving up on some cash before heading to the market so that you can get yourself an air compressor from a renowned brand.

Product Placement

Placing your air compressor on uneven, hard surfaces will produce more sound since the device will be more likely to get displaced from its original position when it is being used.

Before you buy a compressor, or even if you already have one, look for a new, leveled space to place your equipment in, and we can assure you that you will immediately witness a drastic reduction in the sound being produced.

Exhaust System

A perfectly working exhaust system plays a very important role in noise production, and we cannot stress enough the necessity of getting an air compressor with a good exhaust system.

Now that we have taken a look at the various causes behind why your air compressor is making so much noise (and do remember that the list is not limited to just a few mentioned above),let us now move on to discussing the solutions to the main question of the day: how to make the air compressor less noisy?

Here's the guide you can follow:

Lubrication of the Parts

Often, your compressor will be making a lot of noise due to the friction created between the bearings and the other parts of the device. The best way to reduce friction is to lubricate your device frequently with grease.

Not keeping your device well lubricated will also cause it to wear out easily, and as a result, the total lifespan of your air compressor will decrease greatly.

Using Rubber Grommets on the Compressor

As mentioned earlier, your air compressor may also produce noise due to vibration, and one of the most effective ways of dealing with this is by placing rubber grommets between your compressor and the surface on which it is placed.

Needless to say, high accuracy is to be maintained when fitting the rubber grommets so that at the end, your compressor remains on an even surface. Although using rubber grommets will not cut out all the noise, but it will definitely help to make them sound more bearable by abating it considerably.

Placing Your Compressor Some Distance away from Your Workstation

This method is effective because if the air compressor is some distance away from where you are working, then there will be a lesser chance of its noise reaching you.

Nevertheless, you will be required to use a large hose (depending on the distance you wish to keep your device at) so that the air it takes in can be properly delivered to where you are.

In order to support the hose, you should consider getting brackets so that the hose does not get misplaced after some time. You will find the noise level to be rather low after the installation of the hose.

Similar to rubber grommets, this will not cut out all the noise completely, and if you are aiming for thorough quietness, then you might want to spend some extra cash and get yourself a silencer installed for the compressor.

Placing the Compressor on a Padded Area

As mentioned earlier, placing your air compressor on hard, uneven surfaces will increase its noise level because hard surfaces are more prone to reflect the sound incident on them by manifolds.

A great way to stop this from happening is to pad the walls around your compressor. The padding will absorb most of the sound created by the device, and as a result, less sound will get the chance to bounce off of the walls hence greatly reducing the noise level.

Using a Soundproof Blanket to Cover the Air Compressor

This method is similar to the one stated before and is suitable for those who cannot arrange a way of padding their walls. Soundproof blankets act in a way that is similar to padding and is made out of fiberglass or polyester material.

These materials assist in the absorbance of loud noises and can, therefore, also be used to cover your air compressor. Another way of using these blankets is to hang it on the walls of the room where the compressor is kept, although this might be less effective than covering the device itself.

Purchasing a New Air Compressor

If you find yourself still getting irritated by the sound your air compressor is producing even after following all the methods discussed in our guide, then we would suggest you get a new compressor instead.

While purchasing it, you should remember to get a moderately expensive compressor. Well-known brands are more likely to create quieter air compressors due to the fact that they have a reputation to uphold.

Even though this would be a bit heavy on the wallet at first, but in the long run, it will save you from the additional expenses of getting new parts or paddings. Check the noise level of the product.

Before you confirm your purchase, you should ask the retailer to show you the noise level of your new air compressor. Do some more research on what to expect so that they cannot trick you into believing otherwise.

The maximum noise level that your compressor should be 70dB. Any value more than this will prove to be unbearable.


Do remember to do your own share of research as well before you start working on the noise level of your compressor in order to ensure that you will get everything right.

This brings us to the end of our guide on how to make an air compressor quiet. We hope this article was helpful to you. Thank you very much for staying with us until the end!
