How To Make An Air Compressor Quieter

In our everyday lives, we use different types of home improvement devices. Such as spray painters, grinders,  nail guns, sanders, and jackhammers. We need an air compressor for operating them. But an air compressor creates a heavy noise. That is very annoying and also it disturbs neighbors. 

How to make an air compressor quieter? You also want to know that, right? We will tell you 10 tips to make an air compressor quieter. We hope that it will help you and you can quieter your compressor.  

We will give you 10 options to make a quieter compressor and you can choose one or more. We recommend you, read all the options. Then apply any one option that you want and fixed with your compressor. 

10 Tips To Make An Air Compressor Quieter

How to make an air compressor quieter? It is a common question for all compressor owners. There have so many options to make a compressor quieter. For example, by wrapping the motor, moving the intake, encapsulating/blocking off the compressor, or covering the intake with a muffler. You also can use a rubber grommet around the compressor or buy a new compressor with a silent device.  

If you want to buy a compressor, choose a less noise-level compressor. You can do anything to make silent your compressor. Now we will discuss how to make an air compressor quieter.  

  1. Create an acoustic barrier between the air compressor and workspaces

Creating an acoustic barrier between the air compressor and the workplace to reduce the noise level. But how do you create the barrier? We will discuss it. 

A closed room with a sound-dampening wall will help to reduce the noise level. You can place your compression in a closed room with a sound-dampening wall. To create the room you have to use heavy materials such as concrete blocks. Because concrete blocks provide more sound-dampening effects than thin wooden walls.

Make sure the room has enough space and adequate ventilation to prevent overheating. Create a proper ventilation system according to the manual book of your air compressor. It is very important to prevent accidents.  

If you have a small air compressor, you can use a muffler instead a dedicated room. 

  1. Cover the air compressor with a muffler

Covering your air compressor with a muffler is another option to reduce noise. You can use welded mufflers. It works very well. In the market, you will get different types of mufflers. You can choose anyone.   

 To set the muffler, you have to find the intake of the compressor. Then, plug in a two-sided air hose. One end is on your muffler and the other is on your intake. Connect the first hose to the other one.

Though it is a tough job. But it reduces almost 4dB of your compressor. So you can cover your air compressor with a muffler. 

  1. Encapsulate or Box It up

To make an air compressor quieter, you can encapsulate or box it up. That means, separating your compressor from the workplace. You have to make a spare room where you set the compressor. Create a room soundproof with soundproof materials. You can use acoustic foam or other materials to make the room soundproof. After doing all the tasks, make sure you can’t hear any noise from the compressor. 

 Remember, the room must have enough space and adequate ventilation. Otherwise, the compressor will warm up and create overheating. In this situation, it will fail and not work properly. Even, it will cause fire or explode. 

Making a soundproof room for an air compressor is costly. But you get a good result.

  1. Check the lubrication level

Checking the lubrication level is very important. Because an air compressor can operate smoothly with a good lubrication level. 

You must check the oil level several times a week if your compressor is designed with an oil flood. You have to make sure the oil level never runs low. Change the oil once a year or more, it depends on your operating times and compressor model.  

You also need to grease the bearings of the motor. A well-lubricated compressor will last longer and sound better.

  1. Install an intake silencer 

An intake silencer is a muffling device. It reduces excessive noise and dampens the sound of inrushing air with sound-deadening materials or tubes. It also works as an intake filter.  

You can install an intake silencer. It reduces the excessive noise of your compressor. An air compressor creates a lot of noise that resonated from the air filters and it creates high-frequency pulsating noises. An entail silencer absorbs this high-frequency noise. 

  1. Change air filters

An air compressor has to work hard if its air filters and intake filters get overloaded. In this situation, the motor is working hard and creates more noise. So you have to carefully load the filters. 

Also, you have to change intake filters if they become worn or dirty. It is good to change inline filters once a year or after using 8000 hours. You can monitor the pressure drop to check when filters are loaded. 

  1. Move a noisy air compressor away from workspaces

You can move your air compressor away from workplaces. It will reduce little bit noise. Create a separate room for the compressor. Or, move your compressor to a distant corner where people are not working. It helps to reduce the noise level. 

The more distance between your compressor and the place where people work, the more noise will be tolerable. So you can place your compressor outside of your workplace. But make sure the distance will not be too much that will hamper your work. 

  1. Tighten up all the parts

Operating your compressor for a long time, the pistons, rattles, or other parts become loose for vibration. So you have to maintain your compressor from time to time. Check and tighten up all the loose screws or bolts. Before starting the compressor make sure all belts and bearings are not loose.  

Regular maintenance reduces excessive noise and also prevents more costly repairs. 

  1. Set the compressor on a rubber mat absorbs vibrations

Vibrations are another annoying part of an air compressor. Your compressor becomes noisier for the vibrations. Vibrations create a movement in the rotors or pistons that can transfer to the other parts through the floor. That is called noise transfer.  

You can get rid of the problem with a rubber mat. Place a rubber mat under the compressor that will absorb vibrations and prevent noise transfer through the floor. You can use plastic or cork. These are also good for absorbing vibrations.  

Using a rubber grommet on the air compressor mount instead rubber mat. The rubber grommet also absorbs vibration and prevents its transfer through the floor. Even works very well.  

  1. Choose a quieter air compressor

Choosing a quieter air compressor is the best way to avoid the noise of the compressor. But how can you find a quieter air compressor? The noise level for an air compressor is varied in the models.

For example, the noise level of Rotary screw air compressors is 70-75 dB. This noise level is similar to the busy highway. A reciprocating air compressor operates with up to 85 dB which is considered a serious nuisance and you have to raise your voice. 

By any chance, you can find out a quieter compressor. But others features can not fix with your requirement. So you have to consider both sides. First, choose a quieter model with others features that you want. If can not find a quieter model, try other ways to quiet your compressor.


Why is my air compressor so loud?

There have so many factors to make air compressors loud. Most of the noise can happen for attribution friction. Also, metal hitting or sliding against metal caused loud. Generally, the moving parts of the air compressor create loud. 

How many dB is a quiet air compressor?

A quiet air compressor operates at 70-80 dB and an ultra air compressor operates at 60 dB. 

How do you fix a noisy compressor?

First, try to find out the problem and then fix it. There have so many options to fix a noisy compressor. 
tighten up all the loose parts.
by wrapping the motor,
moving the intake,
encapsulating/blocking off the compressor,
covering the intake with a muffler
Use a rubber grommet around the compressor
