When you’re an eager DIY-er or simply a professional, you desire a competent air compressor that is efficient in saving your ears from extreme exposure to constant noises in the shop or your garage.

Therefore, for your convenience, we have prepared a mini-guide to help you buy the best and the quietest air compressor available online. My choice is the Hitachi because it is ultra-quiet and oil-free! Check it out at Amazon.

While choosing an ideal machine for your professional gigs or daily routine work you need to be very careful and judge available products precisely on the basis of their merits. Here are some essential factors that you need to consider before settling for an air compressor.

CFM Rating

CFM (cubic feet per minute) rating is an important factor when it comes to purchasing air compressors. The CFM rating allows you to know the total amount of air your compressor is capable of supplying when being operated. A low rating indicates that your compressor won’t be capable of supplying sufficient air needed for the project.

Moreover, as they say, too much of anything is bad for you. The same goes for the cfm of your compressor. You don’t want to go too overboard with it. Striking a perfect balance is extremely important. The recommended cfm is between 0.6 and 2 at 90 PSI (pounds of force per square inch) when you’re using your unit as an additional compressor for a bigger one.

For DIY projects and to power smaller tools, the recommended cfm is 3.0 cfm. For a workshop the recommended cfm is between 4.0 and 5.0 and anything above this rating should only be reserved for industrial purposes.

Tank Size

There’s no surprise to the fact that bigger tanks are capable of holding more air. Air compressors come in various sizes and designs. Select the one with the largest tank so that an increased amount of air is filled in it and you can use two tools simultaneously.

Choosing a machine with a smaller tank will cause air depletion during your job and the air pressure along with airspeed will start decreasing. This in result will cause the motor to turn on to refilling the compressor tank with air which is a huge loss of your valuable time.

Oil-Free or Lubricated?

Choosing between an oil-free compressor and a lubricated one is a tricky decision to make. While oil-lubricated ones only use a tiny amount of oil to make the parts function smoothly, this can also result in the compressor needing constant maintenance and checking. You’ll need to make sure that the oil doesn’t drip in the compressor tank and also clean complex connections and valves regularly.

For this reason, it is recommended to select an air compressor that doesn’t require any kind of lubrication. You might be worried about the noise factor at this point but other available options won’t let you compromise the maintenance factor of your product for a silent one.

Quiet Air Compressors

According to industrial experts, any machine that has a decibel level of less than 80 is known to be a quiet one. If you don’t mind going the extra mile and spending a few extra bucks, then there are a few premium options to consider when it comes to selecting the best quiet air compressor.

Air Compressors with Magnetic Motors

Although they are a little heavy on the pocket, magnetic motors are known not to make too much noise.

Air Compressors with Belt-Drive Motors

These motors are quieter than other standard motors. They are direct-drive and come with a rotating wheel that is wrapped with a belt. However, we wouldn’t consider them as ultra-quiet machines.

Isolated Rubber Chamber for Portable Air Compressors

If portable air compressors are your thing, you can go for an isolated rubber chamber to accompany it. This item will help you nullify the noise and most of the portable compressors already come with it.
