Small Air Compressor Buyer’s Guide

When looking for a product that can help make air-powered tools as powerful as possible, there are certain things to look out for. Not only should they be easy to use, but the quieter the better. These are just two of the traits to expect from the better small air compressors on the market. 

We have compiled the following buyer’s guide that details everything there is to know about these important devices. By the end of it, you’ll know exactly what the better products are capable of.

What To Look For In A Small Air Compressor

Low Maintenance

This starts with being oil-free which thankfully, most small air compressors are these days. This means the user won’t need to keep an eye on how well oiled the machine is for it to run smoothly and can keep the workshop from getting messy due to spills. 

PSI

The power is all-important here and it’s all down to the PSI. The more the merrier but most reliable products tend to offer anything between 125 – 175 PSI. Anything in this range should be enough to help a nail gun work at its maximum and make light work of a variety of projects. This is also important for pumping tires as, without enough PSI behind it, it will not be able to inflate.

Weight

These may be small, but not all of them are light enough to be easily maneuvered around the workshop. This is why it is important to keep an eye on the weight of the product. sure, it needs to be sturdy, but the weight shouldn’t become a reason to not use it.

Tank Capacity

Another consideration as those who have larger projects will of course require a small air compressor with a larger tank. The most these products tend to offer is 10 liters which most will find to be plenty. Otherwise, it is possible to get by on 6 liters for personal projects.

Power Source

Some people like to use gas-powered products, but electric products tend to be more reliable. Most have lengthy power cords that mean the user is not at the mercy of finding the nearest power socket.

CFM

This stands for ‘Cubic Feet per Minute’ which means how much power it can provide to power tools. This can be beneficial for certain tools that require constant power rather than an intermittent supply. 

Low Decibels

Any power tool is going to be noisy when being used, but the small air compressor used to power it does not have to be. Anything around 70 devices is going to be more pleasant to use on the ears and can mean the user feels like they can use it later in the day without annoying the neighbors. 

Something quick like pumping tires won’t be such a big deal but for longer jobs, you want to save your ears from loud machinery. Thanks to modern technology, a small air compressor noise level is not a gauge of its power.

Value

Not everyone needs to use their small air compressor day in day out, which is why it can be a good idea to look for value. There are enough products that won’t break the bank but still manage to offer high performance in terms of PSI and low decibels.

Why Use A Small Air Compressor?

There are many benefits to using these convenient products, and they include the fact that they are compact and easily portable. However, they are also great for the longevity of the tools as they help them last longer. Also, the power this approach gives to the tools ensures they can get a job done faster, with professional results. 

On top of all this, they are competitively priced and are quicker to use than other methods.

What Is A Small Air Compressor Used For?

They are most commonly used for powering tools making them common on a construction site but also at home workshops and for DIY projects. Because of the power they help to omit, they make light work of various jobs where a manual approach can take a lot longer. Some of the most common tools they are compatible with include a jackhammer, nail gun, and a pneumatic paint spray.

Otherwise, they are used to pump tires because of their portable design and most can work in cold temperatures without any issues. Although no two products are the same, only people who use their tools regularly will require the use of a high-end product. 

How Much Does A Small Air Compressor Cost?

Most reputable products tend to range between $100 – $400 and there can be a noticeable difference between both ends. It might be the case that the consumer needs to compromise on some aspects of a small air compressor such as tank size, although top PSI can be around the 150 mark for both. 

What Is The Best Small Air Compressor?

After reviewing multiple products, we found the best to be the Campbell Hausfeld 6 Gallon Portable Quiet Air Compressor. Not only is it 50% quieter than a lot of the competition with its max decibels being just 68, but there is a lot to like. It also has a max PSI of 125 and a 1-year warranty which is something we always like to see. Everything from the soft-grip handle and durable components adds to the value of what is a reasonably priced yet high performing air compressor. 

Oil-Free Vs Oil Tank

You’ll notice that the majority of products are now oil-free, this is because they are low maintenance and not as messy. Oil tanks do tend to be more powerful and are particularly durable, but the convenience of an oil-free product, combined with its reduced noise, mess, running cost, and added convenience makes it difficult to argue against. 

How Long Do Air Compressors Last?

This will depend on the quality of the product and brand reputation goes a long way when it comes to durability. However, expect most reputable products to last over a decade.
