Air Compressor Buying Guide

Take a stroll through your local home improvement store and you’ll quickly see that air compressor designs are plentiful. These machines come in all shapes, sizes, and configurations. It’s important that you put some thought into your purchase. Instead of grabbing the cheapest option you see, you should consider a number of different factors. Taking some extra time to choose a quiet air compressor that’s right for your needs can help you save time, money, and headaches. Here are some things you should be looking for on your hunt.

Motor

Many people assume that all air compressors use the same type of motor. Unfortunately, this often leads to buyer’s remorse. There are a few different types of motors available. While they all do the job they’re designed to do, some motor designs are better suited for specific types of jobs.

Before we start examining the differences between the motors, it’s a good idea to familiarize yourself with what the motor does. The motor in your air compressor is what provides you with the pressure you need to make your tools work. When a compressor is first turned on, the motor will force air into the holding tank. More and more air is forced into the tank until the pressure increases to the upper limits of the tank. Then, the motor shuts off until the air pressure in the tank decreases.

Gasoline Engine Motors
Air compressors powered by gasoline engines are the most powerful. They’re frequently used in industrial applications. If you’re seeking a quiet air compressor, these types of motors should be avoided. They’re not particularly portable and tend to produce a lot of unwanted noise.

Magnetic Motors
As the name implies, these motors use a series of rotating magnets to create a strong magnetic field. Magnetic motors are relatively quiet, especially when compared to gasoline-powered compressors. Furthermore, magnetic options tend to require less upkeep than other alternatives.

Oil-Free Motors
Oil-free motors have grown in popularity in recent years because of how easy they are to use. These types of motors utilize pistons and valves to create air pressure. While they don’t require oil changes, the name is a bit misleading.

Oil-free motors do contain some oil. However, the components within the motor are pre-lubricated at the factory and contained within the motor so that you don’t have to do a thing. They’re also significantly quieter than other options.

Oil-Lubricated Motors
If the sound level is important to you, consider an oil-lubricated motor. These compressors utilize thick oil to regulate temperature and reduce friction. As a result, sound levels are significantly decreased. The only trade-off is that these motors require much more maintenance than their oil-less counterparts. You would need to keep the motor clean and change out the oil regularly. However, once you get the hang of things, these types of compressors can last for many years to come.

Belt Drives
Compressors with this type of motor have a rotating wheel and a belt. These motors are typically reserved for larger air compressors because they take up a lot of room and can provide you with a lot of pressurized air. In terms of sound, they’re quieter than standard motors or gas-powered equipment. However, they’re noticeably louder than oil and oil-free models.

 

Loudness

When you’re checking out air compressors, take a look at its decibel rating. Many manufacturers make this information readily available. If the product is advertised as a quiet air compressor, the decibel level it produces is most likely advertised.

To be classified as a quiet air compressor, the machine has to generate less than 80 decibels of noise. You can easily find options as low as 60 decibels. To give you some perspective about the noise levels you can expect, 60 decibels is equivalent to normal conversation. It’s also as loud as a standard air conditioning unit when you’re standing approximately 100 feet away.

If you’re looking to bring the decibel level down even further, you have a couple of different options. Many portable air compressors have an isolated rubber chamber around the motor. This cuts the noise significantly. Alternatively, you can search for a unit with built-in sound mufflers.

 

Maintenance Requirements

How dedicated do you plan on being when it comes to maintenance? Some units, such as oil-free models, are virtually stress-proof. They require no major work to maintain. Oil-lubricated models, on the other hand, require regular maintenance. It’s an important thing to consider, as failing to provide adequate care to an air compressor can lead to damage and poor performance.

 

Tank Size

Compressors can come with tanks of varying sizes. The tank is where the pressurized air is stored. Naturally, a larger tank will provide you with more work time. They can also be used with multiple pneumatic tools at one time. However, they take a lot longer to fill and require more space. On the opposite side of the spectrum, small tanks are great for portability. But, your supply of air can be used up quite quickly.

When you’re trying to decide on tank size, think about how the air compressor will be used. If the machine is something you plan on using for big jobs, larger tanks are always better. For those who plan on using the compressor for DIY projects and tinkering, a small or medium-sized tank should be just fine.

 

Power and Pressure Ratings

Now, let’s get into some of the technical details. There are two main ratings you need to pay attention. These include the CFM rating, or cubic feet per minute rating, and the PSI rating, or pounds per square inch rating.

CFM Rating
The CFM rating is an important number that refers to how much air a compressor will be able to supply when it’s in use. It’s a measure of airflow. A higher CFM rating means that you will get more air. Generally, a CFM rating below 5.0 is ideal. For light, everyday work, 3.0 should serve you well. However, if you plan on using multiple tools at one, it’s a good idea to get a compressor that’s closer to 5.0 CFM.

PSI Rating
The PSI and CFM rating go hand in hand. The CFM rating is directly correlated to the PSI of an air compressor. It refers to the amount of air pressure a compressor and its respective tank can handle. The most common PSI rating you’ll see is 90. This is the magic number that most manufacturers stick to. There are other ratings available, but 90 PSI is great for most applications.

If you need even more versatility from your air compressor, you can easily find models that offer variable PSI and CFM ratings. They allow you to adjust the machine to fit your particular tools and needs.

 

Frequently Asked Questions About Quiet Air Compressors

Q: Is there such a thing as a silent air compressor?

A: While many compressors are labeled as “Quiet” or “Ultra-Quiet,” there’s no such thing as a silent compressor. These machines will produce some level of noise. As mentioned earlier, there are ways you can minimize it. Many people work a considerable distance away from the compressor. Doing this helps to cut the relative noise level so that you can concentrate on your work.

Q: What can quiet air compressors do?

A: Quiet air compressors can do the same things that standard models can do, which is a lot. Compressors are very handy machines that play an important role in many different industries. They can serve you well when you’re working on your car, when you’re painting, when you’re woodworking, and so much more.

The reason that air compressors are so versatile is that they provide power to pneumatic tools. The air pressure created by a compressor can drive nails, spread the paint evenly, and provide more torque than battery-powered tools.

Q: Are quiet air compressors safe?

A: When they’re used correctly, air compressors are very safe to use. Quiet compressors are a bit safer due to their low decibel level. Noises above 85 decibels can be harmful to you when you’re exposed to it for extended periods of time. Because quiet air compressors produce less than 80 decibels of noise, that’s not something you have to worry about.

While they’re generally safe, air compressors can be dangerous if they’re not maintained properly. One of the most common issues that air compressors face is leaking oil. If oil gets into the tank and is exposed to high amounts of pressure, it can cause an explosion. Needless to say, proper maintenance is crucial! This is why oil-free models have become so popular. You don’t have to worry about oil leaks.

Q: What makes an air compressor different from other tools?

A: Many experienced workers choose to use air compressors instead of tools powered by batteries or electricity. This is because pneumatic tools are much more powerful and very cost-effective. With an air compressor, you don’t have to worry about putting batteries on the charger. The only electricity you’ll use is from the motor, which is considerably less than a tool you have to plug in.

Not only that, but most pneumatic tools cost a fraction of what their battery-powered counterparts do. This is because there are no electrical components inside. They’re much cheaper to manufacture, so those savings are passed on to the consumer.

Q: Do quiet air compressors need additional accessories?

A: Beyond the oil and other maintenance tools, the only additional accessories you’ll need are the tools and the hose. Hoses are quite affordable and come in a range of sizes to suit your needs. You can also get automatic winders to keep your shop organized or couplers to use multiple tools at once.

Q: Are quiet air compressors portable?

A: Many models are portable. It’s not uncommon to see air compressors attached to a dolly-like frame. A set of wheels make it easy to move to your work site. Portability features are usually reserved for models with a medium-sized tank. If you have a large tank, it will have to stay in one spot.
