Best Quiet Air Compressor Buyer Guide
There are factors to consider when investing in the best quiet air compressor. It’s essential to take these factors into consideration to get a compressor that meets your specific requirements.
It’s obvious you want a quiet air compressor- for this reason, the decibel levels play an important role.
As earlier mentioned, something below 79 decibels is considered quiet to avoid the risk of induced hearing loss and noise pollution to your next-door neighbors, a quiet compressor is a must.
The quietest air compressor in this guide is California Air Tools CAT-1P1060S Light & Quiet Portable Air Compressor rated 56 decibels. However, other options are considered quiet, with all below 79 decibels.
PSI CFM ratings and HP
Cubic Feet per Minute (CFM) ratings are important when buying an air compressor. They tell the amount of air the unit will supply during a cycle.
Compressors with higher CFM ratings will provide more air, making them best for larger applications.
Your best would be something with a range of 0.6 to 5 CFM at 90PSI. If you’ll be using the unit as a supplementary compressor for a larger one, consider a range between 0.6-2cfm.
A compressor with 3CFM is excellent for powering light tools and other DIY projects, while 4-5CFM is perfect for a busy workshop.
Another important factor is pounds per square inch (PSI), which measures the amount of pressure per square inch of space. It’s the amount of force your compressor can deliver.
Horsepower (HP) is the amount of power a motor can perform. This factor is not as crucial as CFM and PSI because newer models work just fine even with less HP. Less HP will help save energy bills.
The bigger the tank capacity, the more air it will hold. Large tanks are great, especially if you will be undertaking major projects and can handle two or more tools simultaneously.
However, for simple DIY projects, you’ll do fine with a medium-sized tank.
Oil-Free or Oil Lubricated
Oil-free air compressors require little to no maintenance. They are mostly preferred over oil-lubricated counterparts.
Lubricated ones require regular maintenance checks and you to continually check that oil doesn’t drip into the air tank.
For example, Makita MAC2400 Big Bore is the only air compressor in this guide that requires oil lubrication.
Simple Ways on How to Quiet an Air Compressor
For some reason, you may find investing in a new quiet air compressor a costlier option or want to make the already purchased one a little quieter.
Below are some different ways to quiet an air compressor.
- Wrap the air compressor using an old carpet or using a sound deadening mat.
- Try to make the intake longer and then move the compressor outside your garage or far from the work area.
- Invest in a quiet muffler and place it on the intake of your compressor
These are just but remedies to keep the noise down as possible. However, note that they may not be as effective investing in a quiet compressor.
Final Thoughts on Best Quiet Air Compressor
Above are some of the best quiet compressors. While these units quieter than traditional compressors, they aren’t 100% dead silent.
