The Quincy Brand
It all started when three employees named George Gille, George Wall, and John Kathe realized that their work in a vacuum design company wasn’t going anywhere. There was no interest in their vacuum designs at all. They then noticed that there was a market gap in the demand for a more powerful air compressor in the American market. The three friends decided to start their own line of vacuum compressors, including production and distribution. They found financial backing to start a brand new company in the form of Elation and Maculae Irwin. By July 1920, the Wall Pump and Compressor Co. located on Quincy’s riverfront was born.
1923 – 1924
Nearing the end of 1923, the company had already expanded its production line greatly. Inspired by the location of the headquarters and manufacturing on the Quincy’s Riverfront, the company decided to change its name to Quincy Compressor Company. The following year, the company expanded its line as well, producing some of the most historic innovations at the time. They had begun selling reciprocating air compressors when the company blew up due to the increasing demand for compressed air.
Years passed and Quincy products were rebranded and geared towards a more specialist product series. In 1937, the company introduced the QR-25 series which continues to be an industry symbol of quality. The same durability and performance capabilities still thrill the market as initially designed. Only a few minor modifications and performance outputs have been made since. These characteristics are present in all of Quincy’s reciprocating line.
The demand for Quincy air compressors was overwhelming that it led to an additional production store at Bay Minette, Alabama, in 1980. It’s also where they began machining and manufacturing their rotary screw compressors and vacuum pumps.
Scaled by the ever-growing demand for quality products, Quincy Compressor Co. expanded into Kunshan, China in 2004. They opened Q-Tech Air Systems, Ltd., where about 35 people are currently employed. The facility was created to assemble and test Global rotary screw compressors. In July 2004, the first official production began, and the facility officially opened in September 2004.
Today, Quincy Compressor is still dedicated to delivering the same durability and performance to suit even the most demanding needs.

We’ve covered the basics when it comes to Quincy product types, now let’s focus on one particular type in which the tested products are categorized under.
Reciprocating or Piston Compressors: Single-Stage and Two-Stage
Reciprocating compressors, also called piston air compressors, are types that rely on a piston inside of a cylinder for their operation. These are compressors with a positive displacement which means air is trapped between two components and then forced to occupy a smaller space, increasing its pressure. These positive displacement compressors are the most common types used for home projects, hobbyist applications, small worksites, and sometimes even in industrial applications.
How does it work?
Generally, as the compressor operates, air fills the upper portion of the cylinder while the piston moves down. This is based on the difference in atmospheric pressure as well as the pressure of the cylinder. When the cylinder moves upward, it’s where the compression of the air occurs.
A single-stage compressor is identified by containing a single piston and cylinder. Standard units are designed to be a single-stage compressor.
Two-Stage or Dual-Stage
With a two-stage or dual-stage compressor, there are two pistons within their own cylinders each. Oftentimes they are set at a 90-degree angle which can look similar to those pistons out of a V-8 engine. This two-stage compressor operates similarly to a single-stage one. The only difference is that it adds another step for compression so it can take advantage of the maximum strength of both cylinders.
Quincy Air Compressor Buyer’s Guide
Now it’s time to break down the information you’ll need as a buyer. Let’s talk about some important factors to consider for your first (or your next) air compressor.
In general, the tank size only matters depending on what kind of applications you need compressed air for. But if we’re talking practicality wise, a bigger tank size is definitely better. Having a bigger tank means that when the air compressor fills up and stops, there’s a larger reservoir of pre-compressed air that’s ready for your next use. A large tank also means that it’s designed to run long enough without having to cycle over and over just to fill it with compressed air. And since the cycle is less frequent, your compressor will reap the benefits of a longer life and less energy consumption.
If you already own a compressor unit and you realize that your tank isn’t large enough, don’t just put a larger tank that it isn’t designed for. Make sure to contact the manufacturer first before going through any alterations and upgrades. Or if you have enough budget, just purchase a new one that carries a larger tank.
For a single stage compressor, you have a choice between 120/240v, 208-230v, or 230v. The key thing to remember here before making any decision is the type of electricity you have already wired for. For example, since most standard homes have 120/240v wiring, going for a compressor with this capability is the easiest because it means there’s no need to install any new electrical wiring. If you choose differently, you will need an electrician to set up the installation to support the higher voltage.
On the other hand, a two-stage compressor isn’t likely to fit a residential setting. It’s mostly used in an industrial setting where a three-phase electricity is found. A three-phase power is more efficient and causes less wear and tear on your motor. If you do prefer to buy a two-stage unit, make sure to consult your local codes and electrician beforehand.
An important measure of what an air compressor can do and how well it can do it is its horsepower rating. Choosing the right horsepower rating depends on what job you’re going to do. Aside from this, the pressure (PSIG) and capacity (CFM) also play a big part in how well your unit can perform in different applications. If you’re quite confused with all the calculations you’re going to do, here’s a list of converters and calculators from Quincy.
The pump is arguably the most important piece of the compressor. The pump should be designed specifically for the application otherwise it will overheat and die. For a single-stage air compressor, a pump with a V-design is best as it will minimize vibration, improve cooling, and overall extend the life of the unit. For a two-stage unit, a cast iron pump with an aluminum head is a great choice.
Size, Weight, and Portability
Air compressors are now available in a wide range of size, so it’s really all up to you and your needs when deciding on this aspect. The most important thing to take note of here is that you make sure that no matter its size, it can still do the job you want or need. Your work area and storage space are also good points to take into consideration.
The duty cycle of an air compressor is the amount of time it can be operated in. It may differ from model to model, and the environment you’re in also matters. Typically, a rating of 100 PSI and a standard ambient temperature of 72-degrees F is used to compute the duty cycle percentage. The most you can get is 100% duty cycle which is an hour of run time or constant duty.
Another important factor to consider is how loud the air compressor can be when operating. Given that compressors aren’t exactly quiet machines, you should be prepared in case it is louder than what you might expect. Think about where you’re going to use it and whether the area can control the noise or not. Consider your household and your neighbors as well.
The last thing you need to consider is how long your air compressor can perform well. A good compressor system will need as little maintenance as possible, so definitely check for reviews before purchasing. Also, the good thing about Quincy compressors is the warranty they offer. They have various extended warranties for their different products such as the Royal Blue Warranty, True Blue Warranty, No BULL Warranty, Blue Shield Extended Warranty, and the 10-Year Heat Exchanger Warranty. Aside from this, they have great customer care and they promote total customer value.

Overview of Quincy Air Compressor Review
It’s no surprise that the compressors from Quincy are one of the most popular and well-known due to their strong performance and high durability. Again, how you choose will solely depend on the application. So before we really break down and compare the four models, here are some reminders to ensure the success of your purchase.
A few reminders…
- Know what your needs are when it comes to operation. If your system or the application requires a variable speed air compressor, consider a unit with speed control. Otherwise, stick to a fixed drive system.
- Really take the time to evaluate how your operations or applications work and see which one will work best. If you prioritize flexibility, a variable speed air compressor allows you to slow down or speed up the process. A fixed speed air compressor, on the other hand, lets you switch on-and-off the equipment, allowing you to build the pressure based on your specifications.
- Again, take into consideration the size. Generally, an air compressor should be as compact as possible. It would fit better in your work area or in your storage plus it makes it very portable. But if you feel like you need a more powerful one and you could disregard the fact that it’s bulky, then, by all means, go big or go home.
- Check for good reviews, such as this one, before making a decision. See if previous users or current owners are happy with their purchase. Doing so will almost guarantee that you will expect the same.
Now let’s recap. All of these Quincy compressors are of good quality and have good standing in the market. The QT-54, despite being used primarily for home projects and hobbyist applications, offers a great amount of power. It has 5HP and a 60-gallon tank. The Q13160VQ also has a 60-gallon tank but has less motor power than the QT-54, at only 3.5HP. Despite that, its low RPM ensures an operation that’s quieter and cooler. This one’s also great for indoor applications or other light-duty commercial projects. The QT-5 is almost the same with the QT-54 but with a larger tank capacity. That means you can store more compressed air than the 54. Last but not the least, there’s the Q12120PQ which is ideal for smaller and light-duty applications. It has a 20-gallon tank and a 2HP motor. It’s portable and lightweight.
Purchasing an air compressor is an investment. Thankfully, Quincy Compressors is an ideal choice in many scenarios. Take the information you need and buy wisely. For us, we proclaim the Q13160VQ a winner. It’s compact enough for a stationary compressor that has just the right amount of strength and a good tank capacity. It’s made from quality materials that ensure longevity and strong performance.
