Air Compressors and Noise

Friday, March 20, 2020

The sound pressure levels generated by an air compressor are a critical consideration when buying one. Many competitor compressors are inefficient in terms of performance, and sound pollution levels.

Air Compressors and Noise

This is why BOGE Kompressoren's engineers have developed whisper quiet technology to allow our customers to experience peak efficiency and performance, without intrusive noise pollution.


In this article, we are going to explore how noise pollution affects air compressor users, why some compressors produce unwanted noise, and what you can do to significantly reduce the impact.


Why Noisy Air Compressors Should be Avoided

The level of noise that can be tolerated by the user from an air compressor depends on how a compressor is being used and in what environment it is expected to be installed. There are three issues which need to be addressed when deciding on how much noise your compressed air system will produce:


  1. Neighbors: If your air compressor is being installed in a commercial property bordering a residential area, the amount of noise produced will need to be in line with local sound pollution regulations. Even then, many authorities have regulations of less than 70dbA at day time and 65dbA at night at the boundary of the factory promisors. and this is probably still too loud for many settings. To avoid this problem, you'll want something like the latest generation of our C-2 air compressor design – compact and quiet.


  1. Employees: In industrial and manufacturing environment, too much noise pollution can permanently damage employees' hearing. This is also true in many production environments where large volumes of compressed air are required. Of course, in such settings, protective gear is advised. However, another approach is to significantly reduce any danger to your employees with BOGE's brand new S-4 range takes sound insulation to the next level,


  1. Customers: Businesses which put their customers first, always come out on top. The last thing you want is to deafen your paying customers. This is even more salient in sensitive environments such as medical facilities and amusement parks etc. BOGE's whisper quiet technology. ensuring that businesses can interact with their customers or patients in a super quiet setting.


Why Some Air Compressors Produce Unwanted Noise
Given the fact that extended exposure to noise above 85dbA can permanently destroy the hair cells inside our ears necessary to hear, a loud air compressor can be more than just a simple annoyance.


BOGE produces some of the quietest compressors in the world, but many compressor manufacturers do not have the technology or expertise to do the same. If you have one of these noisy competitor air compressors, there are a number of reasons they may be producing more noise than usual.


These include:


  • Inappropriate sound insulation material used
  • Types of mechanical devices such as fans, motors, Airends used are noisy
  • Debris rattling inside the housing
  • Inefficient air flow internally
  • Poor dampening through inappropriate or loose screws and fittings
  • Low quality components with poor machining resulting in rough abrasion
  • Incorrect repair or maintenance, replacing components with the wrong parts
  • Overall wear and tear, especially in compressors not designed to last long
  • Running an air compressor in a way and in an environment for which it was not designed.


How to Reduce Noise in an Air Compressor

The best way to reduce noise to whisper quiet is to buy a BOGE air compressor with industry leading sound insulation. In the long term, this will save you money with regards to energy usage and replacement parts - BOGE is a pioneer in durable air compressor technologies.


If you have a competitor air compressor and do not currently have the budget to buy BOGE (though our compressors are competitively priced) you could try the following:


  1. Isolate your compressor from its surroundings by using proper isolation mounts and floor dampening.


  1. The noise produced by an air compressor bounces around the surrounding surfaces.  Making some improvements to compressor room by placing acoustic foam strategically on walls and ceilings, you can reduce these waves and limit how far the sound travels.


  1. If possible, you could relocate your compressor further away from you employees or customers so that the noise is not as overpowering.


  1. While some suggest building your own sound insulation box, we highly recommend avoiding this. Sound insulation around a compressor which has not been designed by qualified engineers can catch fire or produce toxic fumes. Instead, you may be able to construct a partition between those affected by the noise and the air compressor. Cooling Air flow must always be protected.


  1. You could also install an intake silencer or ducting to the exhaust air ventilation etc. However, these can reduce performance and affect the ventilation system and volume of air produced which is critical for many applications.
