The best air compressor is a durable and reliable power source for a variety of pneumatic tools around shops, garages, and contractor sites. Air compressors generate noise because of how they work, but the best air compressor is designed to be quieter and reduce noise on the job site, in your garage, or in your shop.
An air compressor uses a piston to force air into an air tank which build up pressure until a preset pressure is reached. When you use the compressed air to drive your tools the pressure is released and the compressor restarts to recover the pressure. The process creates a lot of noise in most air compressors. The best air compressor uses innovative technology to reduce noise and increase durability.
There are a variety of factors that you should consider when choosing an air compressor including the air compressor types, air compressor pump types, power sources, performance ratings comparison, air tank size, and features.
Air Compressor Types
We have a stationary electric air compressor in our garage. Like most stationary models, it has high horsepower with a bigger storage tank that allows it to drive pneumatic tools for longer periods before needing to recover pressure. Like ours, most have a vertical design that reduces its footprint even though it has the large tank.

Portable models come in a variety of styles with smaller tanks that make them easier to transport. They are perfect for light use such as airbrushing or finish nailing. The most popular portable air compressors are the pancake style that have flattened storage tanks that are more compact and more stable. A hot dog style air compressor has a single cylinder storage tank that is oriented horizontally. Some models have twin horizontal cylinder-shaped storage tanks. Heavier portable models may come with wheels and a handle so that they can be moved in a wheel barrow fashion. To find the best air compressor for your needs, you need to decide on the type that works best for you.
Compressor Pump Types
You have a choice between single-stage and two-stage compressor pumps. Single-stage have one or more cylinders that compress air to the desired pressure. Two-stage models use two or more cylinders where the first stage cylinder feeds compressed air to the second stage cylinder that compresses the air even more. By using two-stage compression, more compressed air is forced into a smaller tank than would be required for a single-stage compressor. More compressed air means longer runtimes without waiting for recovery. Two-stage air compressors are used in constant-use applications where tools are used continuously for extended periods. They are also capable of delivering a larger volume of air at higher PSI.
You have a choice between oil lubrication and oil-free pumps. Oil-lubricated compressors use oil to reduce friction between moving parts in much the same way that it works in your car or other mechanical devices. Oil lubrication requires an oil reservoir and you can expect these models to be heavier than oil-free models. The advantage of an oil model is that they are typically more heavy-duty and used in applications that require a more durable and longer-life machine. The disadvantage is that you need to maintain the oil and change it periodically.
Oil-free models are mostly more compact and lighter than oil models and do not require oil for lubrication. They use special material piston rings that don’t require lubrication. They are not as heavy-duty as oil models, but their compact size and light weight make them very portable and the perfect choice for situation where you need to take carry a compressor with you from job to job.
The process of compressing air generates heat. To prevent the pump from overheating, many models come with thermal overload switches that shut off the pump to prevent damage from overheating. Some models come with integrated roll cages to reduce damage to the compressor from the wear and tear of contractor jobs.
Your power source choice is between electricity and gasoline. An electric compressor doesn’t use fuel so it doesn’t generate exhaust gases making it the best choice for indoor jobs. Electric compressors use electricity to drive the pump and may require either 110VDC or 220VDC depending on the running horsepower of the compressor. Compressors with larger electric motors will use 220VDC.
Gas compressors generally produce a higher output and are ideal for job sites where electricity is not available. They generate exhaust gases so they should not be used in unventilated areas.
There are several specifications that can be used to compare air compressors. First is horsepower (HP). The higher the HP, the greater the air pressure (PSI) and the more air that can be store in the air tank. More air means longer run times between recharges.
The pressure generated by an air compressor is measured in pounds per square inch (PSI). It’s common for smaller, light-duty compressors to have a rating of around 90 PSI while larger, heavy-duty compressors will rate at 150 PSI or more.
Airflow in cubic feet per minute (CFM) measures the volume of air a compressor produces at a given PSI. Higher CFM ratings mean more airflow and compressors with higher CFM ratings are generally used in heavier applications like commercial garage pneumatic tool use or contractor construction framing operations.
Standard cubic feet per minute (SCFM) is used to match your tools to any given compressor. Most pneumatic tools have an SCFM rating or airflow requirement that can be used to determine if the compressor your considering can support it. It’s common for the rating to be expressed in SCFM at 90 PSI. Expect smaller pneumatic tools to require SCFMs less than 5 while larger tools might require more than 10. Plan on choosing a compressor with a higher SCFM than you think you need as SCFM can vary during operation. If you need to use multiple tools simultaneously, you will need to account for the SCFMs of all the tools when you choose a compressor.
Air tank size has a significant impact on the applications that a compressor can support. If you’re planning to use your compressor in automotive work or dedicated construction or remodeling projects, then you should choose a tank size larger than 6 gallons. If you’re only planning to use the compressor for small projects and light duty like airbrushing or finish nailing, then a model with less than 6 gallons is appropriate.
When you buy an air compressor, you may find that it doesn’t come with hoses or connectors unless you buy it as a kit. Keep the extra cost of these necessary accessories in mind when pricing your compressor.
We searched contractor forums, automotive forums, manufacturer sites, social media, consumer sites, retail sites, and customer review sites to find the most popular and highly rated portable, low-noise air compressors.
