How We Picked the Best Two-Stage Air Compressors

When recommending two-stage air compressors, we take five features into account. 

 

Power

We start with the amount of power the air compressor can produce. There are two main characteristics of air compressor power: Cubic Feet per Minute (CFM) and Pounds per Square Inch (PSI). CFM refers to how much air the air compressor can deliver per minute (the volume), while PSI measures the force of the air. These two characteristics work together in a crucial balance to satisfy the needs of your application. 

For example, if you’re using a tire inflator, airbrush, or dental tools, then having high pressure is more important than high volume. The opposite is true for paint sprayers, nail guns, and other tools where you need more volume. Many of our best air compressor categories are based on application, so you can be sure we’re recommending the product with the best PSI or CFM—whichever is needed. Finally, both CFM and PSI are determined by the motor’s horsepower, which is another aspect of power we consider, along with the voltage requirements.

 

Reliability

When you buy an air compressor, you want it to last for years to come. That’s why reliability is so important when making our best picks. We start with the overall construction and design. What is it made of? Does it have protective features like air filters to keep out contaminants?

After that, we look at the operation. Is there built-in technology that reduces wear and tear? How does it handle vibration or moisture? Finally, what is its rated lifetime in hours? How many years can you expect this air compressor to last? By examining reliability and durability, we’re making sure you don’t have to buy a replacement every couple of years. 

 

Efficiency

We measure efficiency by how well an air compressor can deliver your air needs with minimal downtime, and at the lowest cost to you as possible. Compressors that can do both very well rank highly because they perform almost continuously, don’t slow down your performance and save you money.  

One of the key measurements in this is an air compressor’s duty cycle, which represents how long it can operate before needing to cool down or refill the air tank. The higher the duty cycle percentage, the longer it can operate continuously without issue. For example, an air compressor with a 50% duty cycle will run 50% of the time without needing a break.  

Efficiency can take many forms in an air compressor, so we look at the whole unit to determine what features are in place to help bridge the gap between cost and performance. For a two-stage compressor, features like low RPM motors, aftercooling technology, a compact design, a high efficiency intercooler, and other physical features that improve compressor life and dependability may be considered in our final ratings.

 

Noise

Sound level is an increasingly important factor, especially in traditionally loud piston air compressors. That’s why we reward quieter air compressors with a higher ranking. The best piston air compressors today are barely louder than the average human conversation.

When you need a compressor running in a workshop, the garage, a tire shop, or on the factory floor, there are certain safety standards that must be met to prevent hearing loss and other problems, like not being able to hear someone shouting. In short, we think you should be able to work on your projects safely and without worrying about going deaf! 

It’s important to point out that the measurement of loudness in decibels is not standardized across the industry, and different manufacturers may test the loudness of their compressors differently. To combat the discrepancies, we typically consider brands that pledge to test their loudness consistently through organizations like C.A.G.I. or publish their testing standards so we can fairly compare them with other compressors. Of course, the best and most accurate way to know is to listen to as many compressors as we can in person and make determinations on our own. 

 

Overall Value

Taking all the above criteria into account, along with price, leads us to an overall value appraisal for each air compressor recommendation. We don’t go by the “cheapest” air compressor alone because you’re going to get what you pay for, and we prioritize performance and quality. The sweet spot of affordability and performance is what we're after.

Two-Stage Air Compressor FAQs 

How Do Air Compressors Work?

Any air compressor for home use, whether you're a Weekend Warrior or running a business out of your garage, will be a reciprocating type, which operates using pistons. An internal crankshaft drives the pistons inside the cylinders in a back-and-forth motion, creating a vacuum that sucks air in when it retracts. When the piston extends back up, it pushes air into a tank or output chamber and pressurizes it. At that point, the compressed air is ready for use. 

 

What is the Difference Between a Single-Stage and Two-Stage Air Compressor?

A single-stage air compressor compresses air only one time while a two-stage air compressor compresses air twice to increase the amount of pressure.

In a two-stage compressor, air comes through the inlet and is compressed by a large piston. It then travels through an intercooler, a copper tubing that helps cool it down, into a second chamber where it is compressed again by a smaller piston. This double-pressurized air is then transferred to the storage tank or output. As a result, two-stage air compressors are better for heavier-duty, professional air applications.

 

What is CFM?

CFM stands for Cubic Feet per Minute and describes "how much" air is produced, or its volume. An air compressor rated for 15 CFM can produce 15 cubic feet of pressurized air per minute. 

 

What is PSI?

PSI stands for Pounds per Square Inch and describes the pressure, or force, of air. An air compressor rated for 100 PSI can produce 100 pounds of air pressure per square inch.

 

How Does CFM Relate to PSI?

When reading air compressor specs, you'll find CFM ratings listed at a certain PSI rating, i.e. 15.5 CFM at 90 PSI. That means that, when the compressor is producing 15.5 CFM of airflow, it is doing so at a pressure of 90 PSI. If you increase the pressure in PSI, the air volume (CFM) will decrease and vice versa. Understanding this is important when sizing an air compressor for your tools and equipment.

 

What Size Air Compressor Do I Need?

When sizing a two-stage air compressor, start with what you'll be using it for and how often. Having to power a pneumatic nail gun every few months will require much less power and runtime than having an auto shop where you're using air tools all day, every day. This will help narrow down what type of stationary compressor you need (single-stage, two-stage, duplex, rotary, etc.). 

Once you've established use and frequency, figure out how much air volume in CFM and air pressure in PSI you need. This should be specified in your air tool manuals. For example, if you'll be running at most three impact wrenches that each require 10 CFM, then you'll need a compressor that can handle 30 CFM to keep up. As always, you can contact us with any questions, and I'll be happy to assist with your sizing!
