How To Make An Air Compressor Quiet? (3 Effective Methods)

Air compressors are machines that may be useful in many situations. Thanks to their popularity, you can purchase one at a reasonable price and use it for a long time. However, there’s one thing left that often bothers the owners: The annoying noise they make.

In today’s article, we provide you with detailed instructions of 3 tips on how to make an air compressor quiet. So grab yourself a seat and enjoy!

Things You Need To Know Before Fixing Your Air Compressor Noise

Air compressors are one of the most powerful machines in your workshop, but they are also one of the loudest devices. Air compressors aren’t exactly silent when it comes to powering the gadgets they operate. Medium-sized compressors can reach a noise level of 40 dB. Larger, heavier machines may reach a higher noise level of above 90 dB.

The primary reason is the location. If your air compressor is located in the same room as you, you will be subjected to the full force of its output. Even if it’s in the same building, you occasionally hear more of it than you’d want. The greater the distance between you and your air compressor, the better.

Another factor that influences compressor noise levels is friction. With all of their moving components, dynamic displacement air compressors have a lot more friction. Positive displacement compressors are less friction-heavy since they have fewer moving parts. They’d be quieter than dynamic displacement compressors as a result.

Finally, the capacity and size of your air compressor are essential in making noise. Low-capacity inflators have a piston that travels at a breakneck speed. The interior of the compressor warms up at the same rate. All of those pieces will be audible as they move.

There are a few things you need to prepare to make air compressors quiet:

  • Decibel Meter
  • Rubber Mat
  • Rubber Grommet
  • Rubber Hose
  • Heavy Duty Air Hose
  • Muffler

3 Methods To Make An Air Compressor Quiet

1. Use a rubber grommet to attach to the motor

Rubber grommets are a typical form of noise-suppression material for air compressor motors. In addition, thick rubber grommets serve as anti-vibration cushions and dampeners for air compressor motors in most cases.

The best attachment location is between the frame of the air compressor and the motor’s mounting bracket. You’ll need to hire a professional or learn some technical abilities before employing this approach. 

2. Increase the amount of air coming in from the outside

It means you should take your compressor’s intake component outside of enclosed areas.

To do so, you’ll need to push the hose extremely tightly into the compressor’s intake and secure it with a bracket.

Now all you have to do is take the hose outside and fix it to remain put. Again, you may need to drill a hole, or you may use an existing one if one exists.

Furthermore, you may utilize some of the rubber grommets from the set that you still have to tighten the hose even more and reduce the amount of noise.

3. Attach a muffler to the intake hose

Attaching a muffler or a silencer to the air intake hose is the final step to quiet down an air compressor. These handy gadgets typically consist of 2 parts: an air filter and a silencing tool.

Once installed, the incoming air passes through tubes made of sound-dampening materials, significantly reducing the noise resulting from the rush of air.

The incoming air also travels through an integrated filter without having its flow rate negatively affected.

Remember that you can use a larger muffler if your specific intake pipe size is nowhere to be found. However, you should avoid installing one that’s smaller, or it’ll restrict the incoming airflow.


1. What is a silent air compressor?

A quiet air compressor is a machine designed with extra noise-dampening features to reduce, if not eliminate, any mechanical noise. It seems to work for smaller workshops with a compressor system near the business workstation. It’s also perfect for factories that have an open-plan layout.

The decibel rating of an air compressor determines how quiet it is (dB). A low noise decibel rating for commercial air compressors would be somewhere between 40 and 60 dB. Anything less than this would be suitable for a much smaller machine, far too tiny for industrial application.

Smaller workshops and factories are better suited for a low-noise air compressor. Our oil-free air compressors are capable of handling mid-weight compressed air volumes per day.

2. What happens if you don’t drain your air compressor?

The consequence of it is that the tank will rust. Furthermore, the drain itself corrodes and eventually stops working. Instead of air, water will fill the tank, and water will emerge from the air hose. Your air tools will not operate properly, and they may fill up with water, perhaps destroying them. When the air is humid, the compressor extracts water from it, which falls into the tank. That is why it must be emptied.


We hope our tips on how to make an air compressor quiet have given you all the necessary knowledge to do the job. Indeed, air compressors are noisy, but there are some ways to make them considerably quieter, so you don’t have to replace your old ones.

Applying our instructions will save you hundreds of dollars and improve your air compressor if you spend a little money rather than a lot of money, which has to be good for your wallet and your ears.
