Buying the Best Air Compressors – Complete Guide

When you set out to purchase one of the best air compressors, there are several terms and features you’ll want to understand. Here are some things to watch for.

PSI

This stands for pounds per square inch and is the most critical factor when looking for a high-quality air compressor. The higher your PSI is, the more guarantee you have that you can complete your heavy-duty jobs with ease.

For example, if you need to use the air compressor to fill up a trailer tire, you’ll want a compressor that exceeds the total PSI for all four of the tires.

Keep in mind that air compressors usually are electric, so the larger the PSI when you’re away from an electrical outlet, the more life you’ll have. PSI is an important factor, but it isn’t the only thing to consider when looking for the best air compressors.

Tank Size

The tank size works together with the PSI to determine if it’s the best air compressor for your needs. Tanks are measured in gallons with higher numbers meaning that it will hold more compressed air at high pressures. The most desirable option in a perfect world is a large tank with a high PSI, but many people shift to smaller, portable units for versatility.

If you need a dependable workhorse, you’re looking for a large tank with dual outlets. Watch out for the tanks that have a significant capacity but low PSI. This is a marketing scheme to trick you into thinking you are getting a high-powered air compressor when you aren’t.

Purchasing a high PSI compressor with a small tank leaves you often recharging while attempting to work. Granted, it will fill fast, but you won’t be able to accomplish a little task without the need to recharge. This isn’t just frustrating but also wastes your time.

The worst option is an air compressor with a low PSI paired with a large tank. This provides the longest operating time, but also the longest time to wait while recharging. You’ll barely get halfway done with something and you’ll have to stand and wait for it to refill.

Small units with a high PSI are compact and easy to carry. They are units for away from home. Even though the tank is small in size, the higher PSI allows for a quick recharge. They pack a punch ideal for small jobs away from home.

This is why you need to always shop PSI and tank size together as an equation. You can’t look at one without the other.

Multiple Outlets

When you have large projects to accomplish, it’s helpful to have multiple outlets. These aren’t generally found on a small tank, so you’ll want to watch for that as well.

dBA

The loudness of your unit isn’t just a concern for the hobbyist, but also to professional contractors. Sometimes, big units are just as quiet as a small unit. Pay attention to both the dBA and how the compressor is built.

A compressor with low dBA that’s built poorly is often just as loud as the 80 dBA unit that’s well constructed. If you are a contractor working on a family’s home, the lower your dBA, the happier your clients will be.

A quiet unit might be so soft; it’s possible not to hear it from the next room. There are two ways to get what you want. First, look at the box and aim to get the lowest dBA with other features you want. Your next step is to read reviews such as these to determine just how loud they actually are.

Air compressors are not ultra-quiet, no matter how they are made. If a brand tries to tell you they are, run the other way.

Weight

How much does an air compressor weigh? It all depends on what type you choose. No one wants to tote around a 90-pound air compressor, even if it does have wheels. Larger compressors have more features, but is the weight worth it to you?

The large, heavy units are best used by someone that won’t be moving the compressor. If it’s staying put inside your shop, then you can go ahead and purchase the biggest, most massive air compressor you can find without an issue. If the machine has wheels, consider what you’ll do if those break down the road.

When you need to travel with one of the best air compressors, especially upstairs, then a larger unit isn’t going to work. Small air compressors are great for home use and tend to be less noisy as well, but they don’t usually have a lot of power or tank space.

Some of the newer, lightweight air compressors have just as many features as the larger ones. Be prepared to pay a little more for this versatility. Weight needs to be a significant consideration, but your PSI and tank size are paramount when picking the best air compressor.

Accessories

13 piece accessory kit - gaugeWhen shopping the best air compressors, you’ll notice that some come with manuals and lots of accessories. On the other hand, you’ll find models that come with nothing but the unit. Keep in mind the cost you’ll have to buy all the accessories you want later.

Keep in mind that some companies will throw lots of additional accessories in the mix to make you think you are getting a deal. The reality is that you’ll probably never use those items, and you’ve overpaid for a product. The best thing you could do is determine ahead of time which accessories you need. Then, you’ll be able to either find a set that comes with those items or plan to purchase them separately.

Warranty

You want to research the warranty of the best air compressors before purchasing. A lengthy and comprehensive warranty covers you if something breaks. If you buy a kit with accessories, it’s important to note that many of the warranties don’t include those accessories for the same time period.

Which Air Compressor Should You Buy?

With the variety of air compressors on the market, it might be difficult deciding which is right for you. If you are a home user, normally a low dBA is the main priority. In addition, most of the larger powerhouses are beyond your price range.

Smaller motors with a large tank allow you to tackle a variety of projects. If you need to store the unit in a tight spot, you’ll want a smaller tank instead. You’ll also probably want something portable, so keep that in mind.

If you have a large home, or you’ll be storing the compressor in a detached garage, then dBA might not be an issue for you. At that point, you could opt for a more powerful air compressor without a problem. No matter what you choose to use for your home, pay close attention to how long the power cord is. Just an extra foot can make a world of difference when trying to accomplish a job. If all else fails, you can also purchase an additional extension cord.

As a contractor or professional, your air compressor needs will be completely different. Depending on how often you use it, you might be able to get away with a small, portable unit. These are also helpful in specific fields like roofing.

If you need to work on a larger scale, you might even want to consider purchasing multiple units. A work-based air compressor is going to be entirely different from a home air compressor. That’s why home users won’t want to buy a unit based on what a professional uses.

Special Considerations for the Best Portable Air Compressor

You need to think about more than portability and lightweight when looking for the best portable air compressor. This line is in high demand with users, so they tend to innovate these machines faster. That’s why PSI is rarely an issue anymore with portable air compressors.

The best way to pick a portable compressor is to look at the efficiency. Portable units are set up to give you a lengthy work session without a recharge. All this is done with minimal weight so it’s the perfect balance for most users.

There are many sizes to consider with a portable compressor. They can easily be carried up and down the stairs, but there are even small enough units to put in your glove box. Keep in mind that the lower in size you go, the fewer features you’ll likely see.

New on the market are tankless air compressors. While they are lightweight and convenient, the power is often not so hot. They aren’t meant for everyday use, but rather for emergency needs. It makes sense for everyone to own a portable unit for emergency tire inflation. The cost is low on these machines and having one is better than being stranded on the side of the road.
