Quietest Oil-free Air Compressor Buyer’s Guide

Once you’ve made your mind to go for a quiet air compressor, you’ll need to equip yourself with the best reviews that will lead you towards an ideal quiet unit. Therefore, you are required to arm yourself with knowledge about features other than sound. Meanwhile, what unit do you term as a quiet oil-free air compressor? Let’s find out.

The decibel ratings determine the noise level of an air compressor. In that, an air compressor with higher decibel ratings makes the loudest noise. The library noise is considered to be about 40 decibels, casual conversation is 60 decibels, the blender noise is 80 decibels, and lawnmower makes 80+ decibels. Therefore, using this scheme can gauge the amount of noise you can allow in your workplace. 

On the other hand, an oil-free air compressor does not use oil to lubricate its contact parts. It involves other technology such as magnetic motors where no parts come in contact. An oil-based air compressor, on the other side, uses oil, thus requires continuous maintenance. 

Why should you get the quietest oil-free air compressor?

The first thing about a quiet air compressor is to avoid health impact. Continuous listening to loud noise can result in headaches, fatigue, or impairing of the hearing abilities. This is called Noise-Induced Hearing Loss (NIHL). 

Another reason is to maintain a peaceful work setting where one can converse without noise disturbance. The oil-free part is to reduce maintenance and extra cost needed to buy oil frequently.

Without much ado, let’s jump into the features to look for when buying the quietest oil-free air compressor:

Decibel Rating

The decibel rating will help you gauge the noise level of any air compressor. However, do not mistake the ratings as they are taken from some distance; thus, it will be louder when you are closer to the machine. Note that 75 plus is considered not to be quiet, and 80 plus is noisy. Therefore, try and get a unit with the least decibel ratings and, if possible, get a long hose and place the air compressor far from your job site. 

Therefore, you should get the air compressor with the least decibel rating for the most comfortable experience.

PSI Ratings

PSI ratings are the parts per square inch. It is the units used to measure the pressure released by the air compressor. Obviously, your tool will need a certain PSI rating; therefore, the compressor must release the required amount of air pressure for compatibility. Small tools like brad nailers or framing nailers require less pressure like 90 PSI, while heavy-duty tasks demand more pressure above 150 PSI. 

You should go for high-end air compressors with two options for CFM and PSI ratings, as it will allow you to perform multiple tasks. Remember, the higher the PSI, the more the power. 

Tank Size

As you can see from our list, we have considered different tank sizes from 2.5-gallon to 20-gallon. An air compressor carries compressed air that is used to power air tools. Once the compressed air is finished, there is a need for a refill. Therefore, the larger the tank, the longer t takes to refill your tank. 

However, in this category, we are looking for quiet air compressors, and it is challenging to find a large tank unit that is quiet. Anyway, you can get a large air compressor of 20-gallon and still produces less noise. 

CFM Rating

The CFM rating is the airflow in cubic feet per minute, which designates the air compressor performance. The higher the CFM, the better, and it is always measured relative to the PSI. Moreover, a higher CFM will prove that you will finish the task promptly before refilling the tank. A CFM of about 3 is okay for light air tools, while powerful tools need 4CFM and above. 

Oil-free or Oil Pump?

Our topic details a quiet oil-free air compressor, but what does this mean? This is an important factor that should be addressed well. An air compressor can be oil-based or oil-free depending on the model and the manufacturer, and both have merits and demerits. 

Oil pumps use oil for friction purposes and will demand frequent oil replacement. This is time-consuming as you will have to monitor the oil levels and carry on frequent maintenance. However, oil-based air compressors have a more extended lifespan. 

On the other side, an oil-free air compressor requires no maintenance as there is no oil to replace. The oil present has been sealed for good. The mechanism by which it lubricates itself is the use of Teflon coating. Here, you will save extra cash that you ought to have used in oil or maintenance. Otherwise, they do not last as oil-based units.  

Budget

What is the size of your pocket? Maybe you can wish for a high-end air compressor, but you can’t afford it. Go for the features that suit you and the best warranty to get value for money. 

Conclusion

In my final words, I would love to wish that our review and buying guide has put you on the right track towards purchasing the quietest oil-free air compressor. This kind will not only enable a peaceful environment but will also check on your health and safety. 

The oil-free component will save you the hassle of frequent maintenance and additional cash spent on oil. I hope you get a model that suits your preference. Revisit our list and make a confident move. Good Luck!
