BUYER'S GUIDE

There are important features to look out for when you’re shopping around for air compressors. Even though it might appear as though every unit is made the same, that is not always the case. Focusing on these key features will help to make sure you’re buying the perfect compressor for your needs.

Types

The first thing you’ll notice when you start shopping for air compressors is that there are a lot of different types to choose from. The two most common include:

Piston compressors: You’re most likely to find piston compressors. They can be used for household and industrial projects alike. While operating, a piston will move up in a cylinder, which shrinks the amount of space the air has. This, in turn, increases the pressure of the air that is soon to be released.
Double rotor compressors: Double rotor models require the use of water or oil to trap and seal air. When the rotors move, the air is pushed into a smaller space which increases the air pressure and pushes it into the compression chamber.

Power Supply

When thinking about the power supply, you’re also going to need to consider where you’ll be using the air compressor. If it’s going to be used mostly at home, you’ll need to choose a model that consumes as little power as possible. However, for industrial projects, you have fewer constraints.

Most air compressors require 110Volts at 15 amps, but there are also models that require 220Volts at 150 amps. In most cases, the more power the unit draws, the more powerful it will be when attaching tools.

Horsepower

Horsepower is another essential feature to consider, as it will determine the usability of the compressor. Similar to a vehicle, the horsepower determines how hard the motor will work when turned on.

A higher horsepower means the air will be compressed much faster, which makes the unit ready to use in less time. Usually, air compressors will give you the total amount of time it takes to fill the tank. This is when you’ll want to take horsepower into account.

Air Pressure

Air pressure is arguably one of the most critical aspects of an air compressor, as it determines how powerful your attached auxiliaries are going to be. For example, a compressor with poor air pressure won’t have the power to drive nails out of a nail gun.

You’ll want to take your everyday tasks into account, as you’ll want a model with a sufficient amount of air pressure to fill your car tires, build a fence, among many other tasks. Ideally, an air pressure rating of 120PSI or more is the best option.

Tank Sizes

Most air compressors are designed to where you can use them without needing to be constantly connected to a power source. With these models, you’ll want to make sure you have a sufficient tank size. When the air is compressed, it is then stored in a chamber.

The larger the chamber, the more air you’ll have to use before the compressor needs to be plugged in again. For everyday projects, a six-gallon tank is ideal, but you can also find tanks that are larger than eight gallons.

Best Air Compressor FAQs

How to Use an Air Compressor?

Since air compressors are everyday tools, they’re incredibly easy to use. It’s always recommended that you refer to the specific instructions for your model, as the steps for operation may differ from unit to unit. Using these simple steps, you can easily use your compressor:

  • Step #1: Before plugging in the air compressor, make sure the power switch is turned off.
  • Step #2: Using the safety valve, release the valve and listen for the sound of hissing air. If the air hisses, slide the valve back into position before starting the compressor.
  • Step #3: Turn the compressor on and give it a few minutes to pressurize, depending on your model. Keep an eye on the pressure gauge on the front of the unit the tank has reached its maximum pressure.
  • Step #4: Using the regulator knob, adjust the pressure of the tank to the pressure required for the tool you’ll be using.
  • Step #5: Begin using your tools. As the tank drops in pressure, the motor should automatically engage to maintain the same PSI during your entire project.

How Does an Air Compressor Work?

Air compressors are incredibly useful and unique tools. Depending on the type of air compressor, it may work differently than other models. As piston compressors are the most common, we’ll discuss how they work.

With these models, pistons will gradually move up into a cylinder. As they move, it shrinks the cavity in which air is stored, which in turn increases the air pressure. As the air is kept in a smaller chamber, when you attach a tool and turn it on, the pressurized air will be released.

How Big of an Air Compressor Do I Need to Run Air Tools?

Air compressors are available in a wide variety of sizes. The main thing you’ll want to consider is how much pressure your tools require, as this will help you to find the right level of power you need.

Ideally, an air compressor with a six-gallon (or larger) tank should be more than enough. Additionally, you’ll want a model that offers at least 120PSI.

How to Adjust Air Compressor Pressure Regulators?

The regulator is one of the most important components of any air compressor, especially if you’re going to be using tools with the compressor. When the main unit is powered on and filled, you’ll then want to attach the air hose as well as the tool.

It’s now time to find the regulator on the compressor. Once you’ve found it, slowly turn the adjustment knob to increase the air pressure as needed. You can also use the knob to decrease the air pressure if it’s too high for the different tools you’ll be using. You will want to make sure the air pressure of the compressor matches the pressure required by your specific tool.

How to Choose an Air Compressor?

There are many factors to consider when you start shopping for an air compressor. You’ll want to make sure you find one with the perfect sized tank, an ideal level of PSI, as well as user-friendly features.

Depending on what you want to use it for, the specifications of your desired unit will differ. For example, household air compressors don’t require as much power as industrial ones.

FINAL VERDICT

Our recommendation for the top-tier air compressor is surely the Campbell Hausfeld Air Compressor. It has the most benefits, is the easiest to use, and has the added benefit of an incredibly low operating volume.

With its built-in rugged wheels, you can easily transport the compressor without having to carry it. Additionally, its design makes it easy to store and use in confined spaces.

Compared to the other compressors on the list, you’ll appreciate the tank size of this unit, as it is eight gallons instead of six. It also boasts a 25-foot maneuverable air hose as well as 17 extra accessories included with every order. You’ll also appreciate the high-quality design that will surely last over years of use.

Hence, if you’re in the market for a reliable air compressor that is highly portable and user-friendly, the Campbell Hausfeld Air Compressor is surely your best option.
