Buying Guides – How To Choose The Best 30-gallon air compressor?

Air Tool Requirements

Make sure you review the specifications sheets of any air tools you have to make sure your compressor meets their requirements. This is particularly important for compressor volume and pressure, as these can differ greatly between smaller and larger units. However, 30-gallon compressors can often meet most of your air tool needs without any problems.


The amount of airflow needed for common pneumatic tools is one of the most important things to consider when buying a 30-gallon compressor. CFM is a measure of airflow. The CFM of an air compressor should be greater than the CFM of the power tool it will be used to power. This will ensure your equipment can provide maximum airflow and not strain.

You will need to stop and refill your pressurized air if your tools are using it faster than the unit can supply. CFM ratings are often set at 90 PSI, which is the standard setting for a nail gun.


The horsepower of an air compressor has no direct impact on its performance. It is an important consideration when shopping for an air compressor. How quickly the compressor fills up with gas will depend on how powerful it is.

It takes approximately 10-12 minutes to fill a 30-gallon tank. Higher horsepower will allow for faster filling of the tank. A professional-grade compressor that is high-performance and has a high horsepower rating will be a good choice.

Voltage requirements

The majority of 30-gallon compressors can operate at 120 V. This circuit can then be switched to 240 V to get the most out of the unit. This voltage increases the air pressure and reduces stress on the unit during startup. Units that run on 120 V and 240 V are good options, especially if you require a machine that will last longer and requires less startup time.


Air compressors make noise just like any other tool. Noise from machines that are in operation can be irritating. The noise can also disrupt a high-level workplace environment.

You should therefore ensure you choose the one that is quiet in operation over the long-term, i.e. Below 70 decibels. If you plan to use your air compressor at home, it is important to check the noise level. The noise of the gas engine makes more noise than an electric compressor, so it is generally quieter than a gas-powered air compressor.


Are you looking for a portable compressor? You need to decide which type of compressor you want, depending on where you intend to use it. A gas-powered compressor will work best if you require one that is portable and easy to move. Other factors, such as the compressor’s weight, make it easier to transport. Your lightweight compressor can be easily transported if it has wheels. In remote areas without electricity, gas-powered compressors can be used.


It must be able to fit in the space you have available and can be moved easily. You should therefore compare horizontal and vertical air compressors in order to determine whether you need to store it on the floor or somewhere else.


The warranty on all the air compressors we have reviewed is substantial. These compressors are also undoubtedly the most powerful 30-gallon air conditioners on the market. They are of top quality and will last for many years with proper maintenance.


Frequently Asked Questions

Do I drain the compressor after each use?

If your compressor does not have a water drain valve at its bottom, and you aren’t planning on using it for more than a few days, you can drain it. This will prevent water vapor from condensing and potentially corroding the compressor. If you are using it often as part of your job, however, you can drain it only at the end. This will ensure that it doesn’t have to work constantly to build up pressure between jobs.

What horsepower is needed to power a compressor that holds 30 gallons of air?

To operate a standard 30-gallon compressor, it may require approximately two horsepower. These machines have different designs so you might find an air compressor with slightly more horsepower. This is good because it allows the motor to refill the tank faster.

What is the average time it takes to fill a 30 gallons air compressor tank?

To get an idea of the time it takes to fill up a tank, you can look at the CFM of the compressor. A compressor with a high CFM will fill a tank faster.

When calculating how long it will take to fill your 30-gallon compressor, you need to consider the PSI. The atmospheric pressure is 14.7 PSI. The PSI of your compressor is the sum of the pressure readings on the pressure gauge and the atmospheric pressure.

Your compressor’s 30-gallon capacity will depend on how high the PSI is and what CFM you use. The value can be calculated accordingly.

We have provided a reference for the time it takes to fill a 30-gallon tank at 30 CFM. It ranges from 0 to 120 PSI.

*To make it easier to calculate, we have rounded 14.7 PSI to 15. PSI. We will add the atmospheric PSI (120 PSI + 15 PSI = 135 PSI) to the PSI on a gauge.

  • 30 gallons equals approximately 4 cubic feet
  • 135/15 x 30, = 270 cubic feet
  • There are 270 cubic yards of atmospheric air at 120 PSI pressure
  • The difference between 270 and 4 is 266 cubic feet
  • The compressor processes 15 cubic feet per hour 266/15 = 17.7 min

It takes 17.7 minutes for a 30-gallon compressor to be refilled at 120 PSI with 30 CFM.

Can I use electricity to run the air compressor?

It all depends on what type of compressor you use. You won’t need electricity to operate a gas-powered compressor.

What is the difference between a single-stage and a two-stage air compressor?

The two-stage compressors are more efficient that the single-stage units. These compressors are better suited for automotive and commercial applications.

What size compressor is required to power air tools?

It all depends on the type of air tool you use and how many you plan to use simultaneously. Because they can produce a greater than average amount of pressurized oxygen without taking up too many space in your garage or workshop, 30-gallon units are more common.
