Intake Silencer

It is an exquisite device to curb annoying noise coming out of the air compressor. The noise is caused by the air intake when the compressor rotates and air passes through a flapper or a reed valve. The air rattles the valve and the vibration on each pulse cause this noise.

The air intake parts are made from an air filter and a silencer. The sound of the intake air is minimized with the help of the silencer and an input silencer would reduce the pulse noise created by the air. When you have to purchase an intake silencer you need to know the thread size on the intake head. These intake silencers have different standard male pipe thread sizes.

Even if you don’t get a fitting intake silencer you can use a short pipe nipple or bell reducers for fitting a larger sized silencer. Try not to use a smaller sized silencer because it would hinder the working of the air compressor. You can experiment with different silencers to find out which one is best for your device.

Isolating Compressor

You have to isolate the compressor because the rigid connections can result in creating a lot of radiated noise. Using rubber isolation mounts for an air compressor can be a great idea. If you have used rigid plumbing you can utilize a flexible air hose for bridging the compressor and plumbing.

A rubber cord can also be used for the power connections when there is no rigid conduit involved with the compressor. It also depends on the type of compressor you are using. These rubbers are budget devices so you don’t have to spend much and the noise problem is resolved instantly.

Compressor Deading Devices

When the air compressor is present in a room the walls increase the noise as they reflect it. It is the same case with any such material in the room and you need to watch out before fitting the compressor near a corner of the wall. One of the bright ideas is to cover the walls or the surrounding area of the compressor with sound-absorbing material to reduce the noise.

Such material is easily available in the market or online and it is a really effective solution.

Fix the Air Compressor Away from Your Space

It would be great if you can put the air compressor away from your living space. You don’t need to install anywhere near you and you will notice a considerable decrease in the noise.

You can make use of a longer air hose so that it can reach your area while the compressor is not anywhere near your location. According to different reports, you can decrease the noise by 1/4th if the compressor is located away from your room.

A Soundproof Box

Soundproof boxes are available in the market and even if you can’t find one you can create one at your home. The soundproof box covers the entire device and it would absorb most of the noise. A soundproof box can also be created by covering all the surrounding areas like walls and floor with acoustical material that would absorb the noise.

The box can be constructed by different kinds of material and tiles. You would find a lot of ideas online so you may have to do a bit of research. You can utilize the insulation foam that comes with the refrigerator or similar devices to cover the device and make a significant difference.

You just have to be careful about keeping the airflow intact when it comes to the compressor because you may have to face overheating otherwise. The ventilation system has to be on point and a simple exhaust fan will do the job to let the cooler air in and get the heat out.

Be careful regarding the insulation material and don’t put it anywhere near the air tank. The air tank needs to remain uninsulated to perform properly as it condenses the moisture in the heated compressed air generated by the pump.


We hope that the tips we have provided will help you minimize the noise of the air compressor. It may take some time but these solutions are effective and you would feel the results in a few days after implementing one of these techniques.

Although it is difficult to achieve total noise cancellation with the old air compressor models but it could be rendered bearable. It is a trade-off and if you want to have a silent machine you may have to go for the advanced models with built-in silencers.
