An air compressor is a device that creates enough power to operate pneumatic tools by harnessing the potential energy in the air and storing it in a pressurized chamber.
They use an electric, gasoline, or diesel engine that forces increasing amounts of air into an onboard storage tank to increase the pressure within.
Air tools connect to the compressor via a hose attachment. Depending upon the size of the storage chamber, it supplies enough high-pressure airpower to operate large industrial equipment on a construction site, all the way down to a smaller model used for household applications.
Industrial-scale air compressors are notoriously loud. They employ a lubricated, belt-driven pump design to power their bigger and more powerful needs.
Lower-demand air compressors employ a small motor to convert electrical energy to kinetic energy. They rely on fewer internal components so there is less to fail, less to maintain, and usually create less noise.
There are several factors to consider when looking to purchase a "quiet" compressor.
Motors have multiple moving parts and, to keep them running smoothly, require regular lubrication. When metal components grind together vibrations are created, resulting in unwanted noise.
Anything that uses oil requires regular maintenance and for oil levels to be topped up.
Many quiet air compressors sacrifice the slight noise difference in favor of an oil-free motor. With zero maintenance to perform, oil-free compressors are becoming increasingly popular.
Measured in gallons, the tank capacity determines how long the compressor can be operated between charges. Larger tanks allow for longer usage and are therefore more compatible with continuous use power tools such as jet washers, sanders, and paint sprayers.
Small storage spaces have an impact on the size of the machine you choose. Corded electric compressors tend to be on the smaller size, enabling under-counter or workbench storage. They vary dramatically in weight, with some approaching 80lbs. If heavy-lifting is an issue, consider a model on wheels.
Explained in depth below, they are measurements of the strength and potency of an air compressor.
CFM is the standard measure of the flow rate forced out by an air compressor.
It is important as it relates to the suitability and efficacy of an air compressor in relation to a specific application.
For example:
Continuous-demand power tools such as saws, sanders, pressure washers, and airbrushes need a high cfm rating for successful performance.
A continually spinning saw might have a rating of 8 CFM.
Applications with an intermittent demand such as nail guns and staple guns need an air compressor with a lower cfm rating.
A brad nailer might have a rating of around 2 CFM.
Multiply the tools cfm requirement by 1.5 to discover the minimum CFM rating that an air compressor should possess.
PSI is the standard measurement of pressure, in this instance, delivered by an air compressor.
It relates to the amount of force in a given area.
Force and area had an inverse relationship;
Most pneumatic tools require a psi rating of between 70 and 90.
Most light-medium duty air compressors have pressures of 90 psi, often much more. The best performance is achieved when a compressor has more force than the tool requires.
However, it is a fine line; too little pressure prevents the tool from a correct operation. Too much pressure can result in it being damaged.
Always consider the psi rating when purchasing a new air compressor.
Using a compressor to power your air tools is a time and cost-effective solution to otherwise arduous tasks. Traditional air compressors are notoriously loud, enough to cause long-term hearing issues for regular users.
Quiet air compressors ensure decibel levels below 80dB; many of the better models operate at sub-70dB. To reiterate, this is quiet enough to stand next to and hold a normal conversation while the compressor is at full power.
Offices, businesses, and homes are just some of the places where nothing but a quiet air compressor will do. In situations where people have to continue their daily business, a quiet compressor enables a tradesperson to continue without causing too much disruption.
Air powered tools are easier and lighter to maneuver than equivalent battery options. They are more affordable, and importantly, air pressure lasts longer than a battery charge.
Long-term exposure to high-decibel noise is detrimental to the operator, leaving them with ringing in the ears or even worse, hearing loss.
Although it is advisable to wear earplugs when operating a conventional air compressor, many people find them uncomfortable, distracting, and they often lead to recurring ear infections.
Switching to a quiet air compressor eradicates these issues and also keep neighbors and family members happy with the peace and quiet.
The speed of an air compressor motor is measured in RPMs or revolutions per minute. As it spins faster, it vibrates and creates more noise. Quiet models employ lower rpm motors to keep vibrations to a minimum.
Uneven and hard floor surfaces invite sound waves to vibrate and create additional noise. Quiet compressors have rubber matting or feet to level out surfaces and to absorb unwanted airborne and structure-borne sound.
Gas-powered compressors rely on a noisy engine to produce high-volume air-pressure.
Electric motor-powered compressors are naturally quieter and ideally suited to domestic jobs.
All of the machines featured in this article are corded electric models that are focused on the domestic market. As they are relatively smaller than the big, gas-powered, industrial compressors, they are automatically quieter.
