Air Compressor Buying Guide
What to Consider When Buying an Air Compressor?
How Do You Plan to Use It?
It is probably the crucial question, and that is why you should ask it first. Your plans with the compressor are the primary factor and the one that should be considered throughout the entire purchasing process.
If you only plan to use the compressor occasionally in your garage, an entry-level unit is a great choice for you. It will ensure the best value for the money, and you will still be satisfied with the performance.
However, if you plan long spells of using the compressor every day, a more durable and powerful unit would probably be a smart investment.
Does Portability Matter?
The next question to consider is whether you need the compressor to be portable. You can find products that are mounted in a single location, and they are very difficult to move from there. These compressors have their advantages, but portability is not among them.
On the other hand, portable units are lighter, and you can easily move them around from one location to another. You can also choose between different levels of portability based on whether you want to move the compressor around the garage, or between job sites.
Do You Need It to Be Oil-Free?
Most air compressors use oil for lubrication and smooth operation. The advancement of technology-enabled manufacturers to make oil-free models. However, oil units remained popular, and for a good reason.
Permanent lubrication might mean improved durability (it depends on the unit). On the other hand, oil-free units are simple to maintain, which might make them a logical choice for newbie users.
What Is the Optimal Noise Level?
Air compressors tend to be noisy, especially if they are powerful. The manufacturers have recently started competing in making their units as quiet as possible. Some are doing that with more success, while others are not as successful.
Most companies will state the exact noise level in the product description. While that is a fine starting point, it may be wise to read a review or two to confirm that the tool can stick to that noise level.
Did You Consider Fuel Costs?
Two most common fuel options are electricity and gasoline. As you will read later, it ultimately comes down to your choice. However, apart from the convenience in using the compressor and versatility, you should also consider fuel costs.
The fuel costs are directly in line with the compressor strength, which is why you want them to be optimal. In other words, you need a unit that can power any tool you want, but also a unit that won’t spend more fuel than necessary.
What Size of Air Compressor Do I Need?
The short answer would be that the air compressor size depends on your needs and possibilities. Here are some factors that you can consider when choosing the desired tool:
Can it fit in the planned location? If you plan a stationary compressor, make sure it can fit in the designated place.
Will you move it around frequently?
If you need to move it around the workshop, or between job sites, a light and compact-sized unit may be a wise choice.
Which tools will you be using? A small compressor can’t power massive tools, and you don’t have to waste money on a huge one if there is no need.
What Size of Air Compressor for Air Tools Is the Best?
It is hard to give a definite answer to that question because it depends on the tool. The general rule is the bigger compressor, the better. However, it would be wise to read the instruction manual for your tool. The chances are it contains information about CFM requirements.
Go ahead and examine that for all air tools you plan to use with the compressor. Find the most demanding device, and make sure the compressor you pick can suit its demands.
A List of the Most Important Air Compressor Features and Specifications
Here is an overview of the basic specifications and features you should consider when choosing an air compressor:
- Weight – if you plan to carry it around often, you need a light unit. Otherwise, you may want a heavy compressor to improve sturdiness and stability.
- Size – size goes hand in hand with weight. The bigger units may be more suitable for heavy-duty projects, but they are not as easy to transport.
- Power – you can read the motor strength in the product’s description. These largely vary depending on your preference. For amateur users, even 0.5HP can be enough, but professionals may need 2.5HP or more.
- CFM – it is short for cubic feet per minute, and it marks the capacity range of the compressor. Once again, it depends on your preferences and expectations from the tool.
- Safety features – it is always welcome for a product to have thermal overload and other safety inclusions.
- Tank capacity – the capacity of the tank can be directly related to the pressure range, and how long you can run the unit without stopping.
- Noise level – most manufacturers will mention the exact “dB” rating their compressor achieves. The general rule is the lower the number, the lower noise level, too.
- Hose length – it can be very important, and significantly affect the versatility of the unit.
Other accessories – nailers, blowguns, and other accessories can spice up the package.
Types of Air Compressors
Let’s make an overview of the most frequently used compressor types:
- Reciprocating compressors
- Rotary screw compressors
- Rotary centrifugal compressors
You may have heard about machines that work on the principle of positive displacement. In this process, the tool increases air pressure by lowering its volume, and that is how reciprocating compressors work.
The tank of the unit captures the air inside, and that is how it achieves high pressure. A piston is moving up and down; whenever it goes down, vapor moves via the intake valve. The vapor goes into the exhaust valve and enters the condenser when the piston goes up.
Pressure in reciprocating compressors varies between 70 and 100 PSI, although it can go up to 250 PSI in some cases. The motor power varies from as little as 1 HP or as high as 50 HP.
- A versatile tool for personal and professional use
- Simple installation and maintenance
- Easy to learn how it works
- It can be noisy
- Compact-sized units can be tricky to find
Rotary Screw Compressors
Rotary screw compressors work on the same principle as the reciprocating units. Factories and other professionals often use this tool because of its impressive duty cycle. More often than not, you can expect it to operate around the clock without stopping.
Instead of pistons, you can find rotors that compress the air to ensure the unit works properly. It can use oil, but it is not necessary, which makes the maintenance process easier.
- Admirable duty cycle
- It can be very quiet
- Optimal energy efficiency
- An oil-free compressor can be more expensive
- Maintenance requires some effort
Rotary Centrifugal Compressors
Unlike the previous two, this compressor type belongs to the category of dynamic tools. They use rotating impellers to pressurize the air. These units are energy-efficient, and they can secure faster rotation that some other compressor types.
Rotary centrifugal compressors do not use any oil, and that makes them suitable for sensitive environments.
- Very reliable performance
- Excellent energy efficiency
- These compressors are mostly oil-free
- It might not be the best choice for high pressures
- It can be prone to producing vibrations
Portable VS Stationary Air Compressors
You can divide air compressors into various categories depending on the specifics that are important to you. When it comes to mobility, you can pick between stationary and portable units.
Portable Air Compressors
If you are looking for a mobile unit that you can easily move around the job site, or between locations, a portable air compressor is a right choice for your needs.
These compressors are light and compact, which makes transporting them as easy as ABC. Some even come with a carry handle. They are extremely versatile, and you can learn how to use them in minutes.
However, limited weight and size can also limit the compressor’s power. That is why you cannot expect portable air compressors to be too powerful. Regardless, most of them can do a great job for most applications, except for heavy-duty ones.
- Easy to carry and move around
- Very versatile
- It is simple to use them
- They might not be as powerful as stationary units
- Their price tag can be high
Stationary Air Compressors
A stationary air compressor is a unit that you mount in a single location, and you can’t move it around anymore. That is the only location where you can use them.
The good thing about this is that they can be incredibly powerful. That secures impressive versatility, but you also need to consider that you need to bring the tool relatively close to the compressor. Alternatively, you can buy a longer hose, but that is an additional investment.
- They can be very powerful
- You can find them at an affordable price
- They are versatile
- They are not portable
- You need to consider the length of the hose
Electric VS Gas Powered Air Compressors
When choosing the ideal air compressor for your needs, you can also consider the power source. In that category, the most common options are gas and electric-powered air compressors.
Electric Air Compressors
The majority of users, especially amateurs, resort to using electric compressors. That makes sense because the only thing you need to do is to plug the unit in a power socket and it is ready to go.
Electricity can provide a lot of power at any given time. It also ensures optimal energy efficiency, but keep in mind that your compressor is not stronger than you need it. Otherwise, your utility bill will be higher than you expected.
It is vital to note that you shouldn’t use extension cords for your and tool’s safety. If you need extra length, invest in another hose.
- Easy to use and suitable for beginners
- Extremely versatile
- Most of them have great energy efficiency
- Some may lead to high utility bills
- It is not safe to use extension cords
Gas Air Compressors
Did you know that gas-powered units use gasoline as their fuel source? That is important to clarify so that you don’t think you need natural gas or propane.
Gasoline can secure a lot of power, and it is suitable to use on the go. Even in the locations where electricity is not available, these units can work.
Availability and portability are the primary benefits of these compressors, but you can also expect them to pack a decent punch as long as you choose the right units. On the downside, they can be noisy, and it is a hassle to set everything up. Regardless, gasoline remains a viable option when you can’t consider electricity.
- Suitable to use when electricity is unavailable
- They are usually very portable
- You can expect them to be fairly strong
- It requires effort to buy and mount gasoline
- They can be noisy
Air Compressors for Personal Use VS Professional
Most manufacturers won’t say that openly, but many of them design units for personal or professional use. Let’s take a look at what the difference is between the two.
Personal Use Air Compressors
Do you only plan to use an air compressor around your home? In that case, you will probably work on light-duty projects, and you need a unit you can rely on at all times. That is why a personal air compressor is usually portable, light, and compact-sized.
These tools are simple to set up, and you can learn how to operate them in seconds. They might not pack a lot of power, but they still provide decent performance. They are easy to move around, which means they are helpful whenever and wherever you need them.
- Affordable cost

A professional-grade compressor must pack an adequate amount of power to fit in that category. These units are both strong and durable, and they are long-lasting investments.
You will probably use these compressors all the time, including when you need a tool for heavy-duty projects. That is why professional units are big and heavy, and that sturdiness and reliability is the reason why they can be costly.
- They pack an extra amount of power
- Incredibly versatile and suitable for heavy-duty projects
- Long-lasting and very durable
- They can be pricey
- Usually heavier and bigger than personal units
Features of the Best Air Compressor for Home Use
Are you a DIY enthusiast that has big plans with an air compressor, but not that much experience in using one? In that case, you want to start slow. Find a product that is easy to set up and operate first.
Next, keep in mind you do not have to splash your cash on the most expensive air compressor out there, especially if you only plan to work on light-duty projects. A light and portable unit might also be a smart choice so that you can move it around effortlessly.
Finally, the gasoline takes a lot of effort to set up as fuel, which is why home users prefer electric-powered air compressors. As for the strength, analyze the tool you want to power with the compressor and pay attention that the CFM provided by the compressor is at a suitable level.
