What Is an Air Compressor?

They are devices that work to increase the pressure of a given gas. Any gas with an industrial use can be compressed—e.g. oxygen, air, nitrogen, etc.

Compression is achieved by lowering the volume of the gas mechanically. The method for decreasing volume will vary depending on the type of compressor.

There are three types of air compressor:

1. Axial
2. Centrifugal
3. Reciprocating.

We’ll tell you more about how each one works below.

In terms of size, weight, and appearance, you have a lot of options. You can find heavy, stationary models or lightweight, to portable air compressors, known as pancake compressors.

How Does a Compressor Work?

An engine is a driving force behind the compression process. The motor can be powered by either electricity or gasoline, determined by the model.

When the machine is on, the air is sucked in through the intake valve. It will then pass through the internal mechanisms where it will lose volume.

The high-pressure gas will then emerge through the outlet valve. The motor will run continuously or in stop-and-start intervals. This depends on the type.

You can regulate the pressure before you switch on the machine, depending on intended use or the tool you’re powering.

The horsepower of the machine will hinge on what size air compressor motor you have. However, this is not the only measurement of power.

The intensity of the pressure is measured in PSI, or pounds per square inch.

The compression itself can occur in one or two stages. Two-stage machines are more powerful, as the gas is compressed twice before discharge.

The volume and rate at which air passes through the unit are determined according to the cubic feet per minute (CFM) measurement.

Compressors can have one or two cylinders (or tanks). Two-cylinder units have a greater capacity for storing air, translating to a higher CFM.

Unlike the PSI, the CFM can be affected by external conditions. For instance, if you’re working in a hot or humid environment, the CFM may decrease.

The same thing can happen if it’s windy outside, as this can impact gas intake. For this reason, most manufacturers use the standard CFM (SCFM), which measures air flow from the compressor.

The accurate CFM (ACFM) is more suited for scientific applications. The SCFM is a rating that’s for ideal operating conditions. That means no humidity, blowing winds, or intense temperatures.

If you’d like to see more details on the inner workings of various types of compressor, this comprehensive video does a fantastic job!

What’s the Difference Between Oilless And Oil-Based Compressors?

Some of these machines require oil to lubricate and protect moving parts inside the unit. Others are treated with long-lasting lubrication during manufacture.

The former group is classed as oil-based. You have to add oil to these types periodically to keep them operating smoothly.

Oil-free units don’t need this sort of maintenance on your part. All the critical moving parts, such as the pistons, come pre-lubricated.

What Uses Does an Air Compressor Have?

Air compressors can be used to power a large number of tools

They have many practical applications. They can be used to power tools, spray paints, inflate tires, and more.

Inflate Your Tires

You can ensure your tires are always inflated to the correct level. The average tire loses between one and three PSI worth of pressure per month, so it needs periodically refreshing with air.

Instead of heading to your mechanic or a garage, you can maintain inflation at home. Optimal inflation can also extend the lifespan of your tires and improve your fuel mileage.

Follow our guide for how to inflate car tires correctly.

Spray Painting

Using even a small air compressor can make a big detailing job quicker and easier. It can be used to power automotive spray or paint guns.

Automotive Tools

All sorts of tools we use on our vehicles can be powered with compressed air. A few examples are ratchets, impact wrenches, and grinders.

Other Tools

Those of you who are handy will find non-automotive uses for a compressor. It isn’t likely that the machine will be used exclusively for your vehicle.

Leaf blowers, pneumatic nail guns, staplers…the list is almost endless. 

Types of Air Compressors

You already know there are three general types with automotive applications. They’re classed according to how they work to decrease volume and increase air pressure.

Centrifugal Compressors

Centrifugal units operate using kinetic, or movement, energy. Air that enters the machine is circulated with an impeller that moves at high speeds.

The kinetic energy then passes through the diffuser, which is a form of outlet passage. Inside the diffuser is where it’s converted into a higher pressure before being discharged.

These types tend to have a higher CFM rate, as they can treat larger volumes of gas. The PSI rating is typically moderate.

Reciprocating Compressors

Most commercially available models are reciprocating. They operate in a similar way to how car engines work.

Pistons inside the machine are propelled by a connecting rod, wrist pin, and crankshaft inside cylinders. The number of cylinders will depend on the size of the machine.

First, the air is sucked into the piston. Next, the piston moves in the opposite direction, decreasing the volume of the suctioned gas.

The gas is then discharged once the PSI exceeds the outlet valve pressure. There are two subcategories of reciprocating compressors: single-acting and double-acting.

Single-Acting

In these units, compression only occurs on one side of each piston. Engines on these types usually run in intervals to regulate pressure and avoid overheating.

Horsepower, PSI, and CFM are on the lower end of the scale. Most systems are not water-cooled, meaning they can overheat if run continuously.

Double-Acting

There are chambers on either side of the piston for compression. The extra chamber allows for higher PSI and CFM.

Double-acting units are often equipped with a water-based coolant system. This enables the machine to run continuously without getting too hot.

Rotary Screw Compressors

As the name suggests, rotors are the driving mechanism here. The rotors mesh together at high speeds, sucking in gas just as quickly. The engines on these models can run continuously or in stop-and-go intervals.

The CFM and PSI of these powerful air compressors can range from minor to major; up to five figures. They’re ideal for powering pneumatic tools that are more complex or require high pressures.

How to Choose the Right Air Compressor for You

There are many factors to consider before you choose an air compressor. Keep all of the below considerations in mind while you’re shopping.

Air Compressor Type: Stationary Vs Portable Air Compressors

We mentioned earlier that these units can come in all shapes and sizes. Stationary air compressors, as the name suggests, can be a hassle to move around. Portable models, on the other hand, are either lightweight or equipped with wheels. You can move them around or transport them without much effort.

Stationary models are larger, meaning they’re more powerful. With lightweight units, the portability might come at the cost of a loss of power (CFM and PSI).

Think about what you’re planning to use the machine for. Will you be moving around your vehicle often? Do you have separate work areas for different vehicles? If so, a portable air compressor might be the best option.

You may have to compromise power for portability. Having said that, if you’re using specific high-performance tools, a stationary unit might be necessary.

One-Tank Vs. Two-Tank

Two-tank models are also known as twin-tank compressors. They can store greater quantities of gas than single-tank units. This makes for a higher CFM rating.

At the same time, twin-tanks are often more expensive. They’re suited to power tools or machines that are more complex.

Consider what you’ll be using the machine for. If the answer is simple applications (e.g., powering a ratchet), you may want to settle for a single-tank device.

One-Stage Vs. Two-Stage

Two-stage units will give you double the compression, resulting in a higher PSI. As with two-cylinder units, they’re on the higher end of the price scale.

As with the number of tanks, review your current collection of tools. Do they all have low PSI ratings? Do you plan on buying high-PSI tools in the future?

Power: Electric or Gasoline

Electricity is cheaper, less messy, and more convenient to use than gas. It’s also less dangerous—no fumes, and it’s non-flammable. You can use electric air compressors indoors or in your home garage safely.

Contrastingly, gas-powered machines can run independently. You don’t have to be near an outlet or get an extension cord to start working.

You will have to make sure you have a well-ventilated work area, though. There’s always a potential risk of carbon monoxide poisoning with small gasoline engines.

As with other points on this guide, fuel choice is a personal preference. Some of you may be uncomfortable handling gasoline or prefer the eco-friendly alternative.

What Rating Do You Need? CFM and PSI

The cubic feet per minute (CFM) and pounds per square inch (PSI) are crucial. There is no right or wrong when it comes to these ratings.

You have to assess the tools you already have and want to buy in the future. The model you invest in should be compatible with everything in your toolkit.

An air compressor must provide sufficient air output without overstressing the machine. Check the recommended CFM and PSI of all your air-powered tools.

Write down the highest CFM and PSI and keep these numbers close by when shopping. Pick a unit that has a higher rating to ensure maximum performance.

Tank Size

The bigger the tank, the greater the power the machine will produce. There’s more space for air storage, hence a higher CFM and possibly PSI.

Remember that larger tanks can impact portability. You have to find a balance between the two.

Oil-Based Or Oilless

Oilless units might seem like the obvious choice here. But before you disqualify oil-based models entirely, take a moment.

Yes, oil-based machines do need to be maintained. Oil has to be changed and replaced, filters have to be kept clean, etc. Not to mention small traces of oil can escape with the air in oil-based units.

At the same time, with proper care, they’ll last you for a long time. Some power tools perform better if they’re lubricated.

The lubrication in oilless models can wear down over time. As this happens, you may hear more noise from the machine while using it.

Despite these downsides, you might prefer to buy an oilless model. There are tools that can be damaged if they’re contaminated by oil traces, such as sanders, so in these cases oilless models are the better choice.

Certain projects can also be jeopardized by traces of lubricant. Imagine you’re painting your vehicle, you definitely don’t want oil mist collecting in the spray gun!

Usage: What Will You Run From It?

What tools or equipment will you be running from the machine? How often do you plan on using these tools? Is automotive maintenance your main focus or secondary to chores around the house?

Take the time to think about all these scenarios in detail. It can be a challenge to find a type that will suit every single item you have in your toolkit.

Nevertheless, you can choose a model that is compatible with most of the gadgets you have. 

How Much Space Will It Need?

Take a quick mental tour of your home garage. Be realistic about how much space you want to dedicate to your garage air compressor, but remember that compact units may not be as powerful as larger ones.

Noise Level

The engines of some models can run loud: pancake compressors are notorious for this, so are best avoided if you prefer to work in relative silence.

Cost and Warranty/Guarantee Offered

These aren’t screwdrivers – you’re going to want some form of warranty for something this expensive. In the event that anything goes wrong, you’ll be able to recoup your investment.
