Introduction
Prolonged exposure to loud noises can have adverse effects on your health. Whether you’re at home, on a construction site, or at a shop, your productivity and health can be affected by constant exposure to loud noises.
That is why it is important to have an air compressor which makes less noise than a regular one.
But buying the right product could pose a challenge if you don’t know how to look for the perfect one.
But don’t worry, we are here to help you.
We noted down below all the facts you should check while buying a quiet air compressor.
Want to know all the details?
Let’s get started.
What to Look for While Buying a Quiet Air Compressor
Buying the right air compressor that makes less noise can be a challenge. Especially since there is a sea of options out there, and most retailers or brands would use fancy marketing tactics to sell their products rather than telling you the right features.
But buying a quiet air compressor is easy when you know what to look for. We’ve noted down all the major features that one should consider for buying the right kind of quiet air compressor.
Now if you’ve already searched the web. Woodworking toolkit has curated a list of the best options out there. So, if you want it to be quiet, look into our suggestions.
What do we have to look for in a quiet air compressor?
Check Decibel
To know how quiet your chosen air compressor is, you need to check its decibel scale. The higher the rate, the louder it will be.
Most quiet air compressors in the market will have tags like ‘ultra quiet’, ‘noise free’ etc, but these tags can’t tell you how quiet the compressor is. To know that, check its decibel rating and compare it with sounds that you are familiar with.
For example, leave rusting is 30 dB, vacuums range from 60-85 dB, the lawnmower is 90 dB, etc. A quiet air compressor is usually under 80 dB. The quietest it can be is 50 dB. If the manufacturer doesn’t mention the decibel rating then it is most probably loud.
Sound Dampening
One of the main features of a quiet compressor is sound dampening.
Pumps in regular compressors are exposed. Which results in an unrestricted blast of sounds. Quiet air compressors are produced using thicker gauge steel or aluminum. Which avoids producing noise blasts. Quiet compressors also place dampening pads to reduce the vibration. This restricts the sound waves made by the compressor
Rubber Components
Vibrations released by air compressors cause further amplification of sound. So, having rubber isolation pads is a solution for this. They can help to tone down the severity of the sound.
The pads avoid the vibration made by the compressor to reach the floor. Rubber isolation pads along with other features like sound dampening can produce less than 70 decibels of sound. This range of sound is seen in a 1-on-1 conversion. That’s way better than 90 dB, which has the possibility of permanently damaging your hearing.
Oil vs Oil-free
While searching for a quiet air compressor you may stumble on a debate on oil vs oil-free compressors. Many people do not prefer oil-free compressors because they are noisier than oil compressors.
This might be partially true. But many air compressors are oil-free and quiet at the same time. Manufacturers are now making oil-free air compressors for the dental, medical, and food industries. Some examples are scroll, rotary screw, or reciprocating pump that had a dual-piston design.
Types of Air Compressors
Even if you ensure all the features mentioned above, there are still other options for you to choose from when it comes to quiet air compressors. While buying a quiet compressor you need to choose one that best fits your requirements.
Type 1: Reciprocating (Piston)
One of the most common types of compressors is the reciprocating piston pump. For namesake, it has a similar piston that is seen in the engine rotating in a chamber to compress air. The movements are in a swift up and down motion to capture air, similar to the size of the piston.
Dual-piston compressors produce less noise than single-piston ones, as they produce more air with lesser revolutions, allow better cooling, and have more tolerance. Some other features that you can look for in quiet air compressors include low RPM, cast iron cylinders, ASME certified tanks, and compressors that come with an equipped aftercooler.
Type 2: Scroll
Scroll air compressors are the quietest and most efficient than other air compressors. In order to compress the air, two spiral-shaped metal pieces are used. One-piece remains stationary and the other is fitted inside and keeps moving in a circular motion to create the compression.
These compressions are manufactured to run consistently and are great for many commercial usages like food, pharmaceutical, medical, textile, production, etc facilities. Even though scroll compressors are supposed to run continuously all day they do have a drawback. That is, their CFM capacity is very limited.
Type 3: Rotary Screw
Rotary screw air compressors are quieter than reciprocating compressors but not as quiet as scroll compressors. They have a positive displacement compression system that features a matching pair of helical screws. The helical screw doesn’t touch each other, making this compressor quiet.
They are found in both oil-injected and oil-free compressors. Though oil-free models are more expensive, they are better in quality and are needed in the food and medical industries. A major benefit of these compressors is, they can be placed close to the workspace without the need for hearing protection.
Conclusion
We hope this article helps you to buy a quiet air compressor according to your requirements.
Buying a quiet air compressor might seem redundant to you. But no matter what, one should never put one’s health at stake. A quiet air compressor will ensure safety from sound pollution.
We hope you found this article helpful. We have tried to provide you with all the relevant information that might be needed.
Thank you for being patient and staying with us till the end.
