To avoid buying an air compressor and realize you bought the wrong model, it’s vital you figure out the best size air compressor you require. The following points will help you determine what type and why the size of air compressor you need for your home use.

Types of projects

Do you need an air compressor for big construction projects or occasional maintenance jobs? Are you looking for an air compressor for a home upgrade of automotive repair? You need to figure out what type of activities you will be using the air compressor for. If you’re planning on putting up a shed in your backyard, you need something sturdy.

Types of air tools

Some air tools, especially those that need constant air flow like a sandblaster or a vibrator, you need an air compressor that has a bigger air storage tank and a high airflow. But, to operate something with occasional stops like a brad nailer, a small portable model will do.

Power source

A most portable air compressor can plug into a typical home power outlet while others do even use battery power. However, some large models require a 240-volt power source.

That means you need to check what system you use in your home; is it a three-phase or a single phase. If a single-phase then you cannot use a 240-volt air compressor, but if you have a three-phase and you use a 110-120-volt system you can hire an electrician for an upgrade for the unit.

Space available

How big is your storage unit? If you have small storage space, I would recommend you go for a portable model that comes with a little or no air tank, and if you have a big empty storage space the bigger, the better. A portable six-gallon air compressor can be great for most of home pneumatic tools and great for small storage space.

Place of use

If you’ll be undertaking your projects in one workplace, a garage or workshop, there is no need to worry about your air compressor design. However, if you plan on moving your tools around and frequently, you’ll need an air compressor that is lightweight, portable and easy to carry, probably with a handle(s) or wheels.

Air Tool CFM Requirements

The airflow rating on an air compressor is the most crucial thing you need to pay attention to when searching for the best size air compressor for home use.

Noted as CFM-Cubic Feet per Minute or SCFM-Standard Cubic Feet per Minute, should at least meet the minimum CMF rating requirement of the air tool you’ll be using. And since the compressor CFM changes depending on the set pressure (PSI), it’s better to use the CFM at 90 Psi air compressor rating while comparing the units.

Every pneumatic tool has a recommended CFM that’s is set by the manufacturer, if not met the machine might not underperform or not work at all and if exceeded the tool might get damaged. F

or you to determine the CFM rating, you will need to run your air compressor, take the highest CFM rating of the air tool you are planning to power, and multiply it with 1.5.

That way you will get some wiggle room as CFM can vary while in operation, and you might also want to connect multiple air hoses to power a couple of air tools at the same time, if your air compressor allows it, or you might need to upgrade your air tool in future.

An air compressor horsepower is yet another common rating touted by the manufacturers of these units. It isn’t as important as the CFM rating, but it will give you a broad idea of the strength and powerfulness of your compressor power. The air compressor’s horsepower helps in determining how to power the motor is in filling/refilling the air tank.

Tank Size

The sizes of an air compressor tanks vary from 1 gallon to 60 gallons or even more. The air tank determines how long your air tool can run before exhausting the air and requiring the compressor to turn back on and pump more compressed air.

As I said before, specific pneumatic tools require continuous compressed air flow, and as such, they need an air compressor with a bigger tank than those that operate with short air flow bursts. The less the number of on/off cycles your motor has to undergo, the longer the lifespan.

Having given you the pointers to use to determine the best size air compressor for home use, it’s time now to provide you with the top three models ideal for home use. I have researched through and selected three models that would be great for different DIY projects and automotive repair, reviewed them and prepared the review below.

All the above information is there to ensure you get the best side air compressor for home use and the best model. Believing you have gone through it and you have understood what you need to check to buy the best model, it’s time for you to head out there and get a model that will suit you best.

Ensure you use a well-planned budget to prevent overspending. Additionally, proper maintenance will help in improving your air compressor’s durability.
