When selecting a compressor, it is worth paying attention to its noise level as it’s difficult to work comfortably in a noisy environment for very long. The noise of your air compressor may affect if you’re able to position it near the point of use or need to implement acoustic barriers in your compressor room.

When shopping for a quiet air compressor, there are many terms used including ‘silent’, ‘noiseless’ and ‘ultra-quiet’. But what does a silent air compressor or quiet air compressor actually mean? 

An air compressors noise is measured by decibel rating (dB). The higher the rating, the noisier the air compressor will be. 

  • 40 dB – This is considered low noise and is found most often in small air compressors or air compressors for domestic use. 
  • 60 dB – This is considered the safest level of noise for air compressors. 
  • 85 dB and over – This level of noise can become dangerous if exposed for long periods of time. 

No silent air compressor will be completely silent, but noise can be dramatically reduced by choosing a quiet air compressor model.

Why Are Air Compressors So Loud?

There are a few different reasons why air compressors are so loud, the first being friction. Some models, such as reciprocating compressors, have a higher number of moving elements that are in contact with each other and generate a lot of friction during the compressing process and can cause a lot of noise.

The second reason for a loud air compressor is the power source. Silent air compressors are typically powered by electricity to reduce the noise. Gas-powered air compressors will always produce a higher volume when being operated.

Lastly, your proximity to an air compressor will have a huge impact on the noise levels, the closer you are, the louder it is going to be. In some situations, it is not possible to isolate staff or even clients from an air compressor and therefore a low noise air compressor can be the best solution.

While there is plenty you can do to quieten the sound on a compressor, there are low noise air compressors available that don’t require any additional tricks. These machines are available in both oil and oil-free, depending on the intended application. Our low noise air compressors are available in 7.5-10 BAR capacity and can cater to any task you need.

Why Choose a Silent Air Compressor?

There are plenty of reasons why you should choose to invest in a silent air compressor. Reducing noise in the workplace provides your employees and visitors with a more comfortable environment while simultaneously reducing the risk of any negative health problems, such as tinnitus, which can be a direct effect from working with air compressors in close proximity.

Productivity can be improved, by reducing noise with a low noise air compressor, employees are less likely to be distracted and are able to concentrate more and work more efficiently. Without the need to raise voices to be heard, colleagues can communicate clearly with each other.

Popular Industries

Dental

Within the dental industry, compressed air is used for several point of use applications. A dental air compressor is usually installed in a clean, central location where it can power multiple surgeries or in equipment including dental carts and chairs, meaning ultra-quiet air is a key requirement.

Healthcare

Minimum noise and vibration levels are crucial within the healthcare industry, with compressed air being used throughout critical areas such as operation rooms, ventilators and drying of medical devices.

Scientific

Scientific and research laboratories need compressed air for cleaning, distillation, filtration and other purposes and at silent noise levels.

Pneumatic controlled systems

With the ability to be in the work area whilst not causing any noise intrusion, silent air compressors fit as solutions for other pneumatic controlled systems too. Smaller breweries with processes such as canning machines are a common example.
