What’s the Best 30 Gallon Air Compressor?

Choosing the best 30-gallon air compressor can be complicated depending on what your requirements are. It can be daunting to make the right decision because air compressors are highly specialized. It can be confusing trying to understand the technical aspects of the compressor. Bearing that in mind, we put together this detailed article to guide you through the process of selecting the best 30-gallon air compressor for you.

We talked a lot about 20-gallon air compressors in the previous post, but what about 30-gallon compressors? Why do you need a bigger air compressor to get the jobs done? The right answer is “BIGGER is BETTER!”. A 30 gallon air compressor will hold more air and allow you to use your tools longer before the pressure drops and the motor kicks on to refill the tank. Also, some 30-gallon models are designed to have a very high CFM rating – up to 25 CFM at 90 PSI – which is better for using heavy-duty pneumatic tools like sanders, grinders or impact wrenches.

30 gallon air compressors range in price, based on a variety of criteria including type, design and available features. Portable units, such as Industrial Air ILA1883054 30-Gallon Belt Driven Air Compressor, usually cost $400 – $800, whereas truck-mount units, such as DeWalt DXCMH1393075 Two-Stage Industrial Air Compressor, can cost more than $2000. As you may have noticed, there is a major difference in price. So it’s important to choose a compressor that is durable, reliable and capable of providing the right amount of air pressure to your tool but at a price that you can afford.

We reviewed many 30 gallon air compressors available on the market and only 5 models match our requirements, all others lacking one essential feature or another. We hope this guide will help you choose the best 30-gallon compressor to suit your needs and your budget.

Why should I buy a 30-gallon air compressor?

Air tools have become a staple on many jobsites due to the simplicity and advantages they provide. In fact, it’s estimated that nearly every industry now relies on compressed air tooling to some degree. Among their greatest benefits are that they offer the freedom from electricity and don’t require their own motor – especially useful in rural areas or temporary locations like fairgrounds or music festivals. But for these tools to perform in locations that range from urban to rural, they do require the support of an adequate air compressor.

An adequate air compressor is a compressor that is capable of providing the right amount of air pressure to the air tools that you’re going to be using. Air tools come in a number of different forms, and each tool requires a different amount of compressed air to get the jobs done. It’s can be difficult to determine which size of air compressor is the best for you. An air compressor that is too small would be not enough to power the tools that need a lot of air volumes like impact wrenches or orbital sanders. One that’s too big will not be suitable for construction sites, road works, or wherever you need compressed air. Sometimes we need an air compressor that is portable but powerful enough to run all pneumatic air tools available or for using multiple air tools at the same time. That why you are here to read about 30-gallon air compressors. A 30 gallon air compressor is the best compressor for any heavy-duty application on construction sites.

When it comes to choosing an air compressor for a work truck, a truck-mounted air compressor is the most common choice. And the most common size of truck-mounted compressors is 30-gallon. The truck-mounted models, such as Ingersoll Rand 2475F13GH Two-Stage Gas-Powered Air Compressor, provide plenty of CFM up to 27.3 CFM at 90 psi which is able to handle any air tool you have. You know sanding is one of the most exhausting tasks in woodworking, and random orbital sanders are the most air-consumed tools among all. They require average 8-12 CFM at 90 PSI to run, and the model above provides more CFM than the requirement.

How to Buy the Best 30 gallon Air Compressor?

When shopping for the best 30-gallon air compressor, you will need to decide on what type of unit you will need to purchase. Truck-mounted or portable compressor? Electric or Gas-Powered compressor? How many CFMs and horsepowers do you need? And what features you should look for. Regardless, of the type of air compressor you wish to purchase, you’ll want to choose a compressor made by a reputable manufacturer that comes with a good warranty and offers a complete line of accessories and replacement parts.

In terms of reliability, we would suggest you buy your 30 gallon air compressor from top brands such as Dewalt, Industrial Air, Ingersoll Rand, Porter & Cable, Campbell Hausfeld, and Quincy. You can easily find their products on Amazon. These types of compressors will be a lot more money than the ones from Chinese manufacturers, however, they are made to withstand continued use and offer a good service for many years.

Truck Mount or Portable Air Compressor?

The entire purpose of a service vehicle is to be versatile. Whether you are working on the oil field or offering roadside services, having the ability to work onsite could make a world of difference. Truck-mounted air compressors may be the answer to that vital question. Adding a 30 gallon truck-mounted air compressor to your truck will allow you to carry every type of air tools you have and give you everything you need to function on the job.

Most 30 gallon truck mount air compressors are gas-powered. They’re designed to be used for outdoor applications, not for indoor use. You should buy this type of air compressor if you want to install an air compressor directly to your service truck. A 30 gallon truck-mounted compressor can provide compressed-air at a very high CFM, but it can be very expensive to buy.

30-gallon portable air compressors, on the other hand, are designed to be used for both indoor and outdoor applications. Most of these compressors are electric-powered and require less maintenance than truck-mounted models. They are also less expensive and quieter. However, 30 gallon portable air compressors have much lower CFM and horsepower than truck-mounted models. A typical 30 gallon compressor, such as the DeWalt DXCMLA1983012 30-Gallon Air Compressor, delivers just about 6 CFM at 90 PSI, which isn’t enough to run 1-inch impact wrenches (require 10 average CFM @ 90 PSI) and orbital sanders (require 6-9 CFM @ 90 PSI).

CFM is the Key

CFM (cubic feet per minute) tells you how fast an air compressor can supply air. And it’s usually the most important number to consider. If a tool uses air faster than the compressor can supply it, you’ll have to stop working and wait for the compressor to catch up. Every manufacturer tests its compressors at 90 psi – an average setting for a nail gun – so you can be confident that you’re comparing apples to apples when you look at CFM numbers.

The chart below includes some common air tools and their average CFM measurements. Reference this chart to determine what continuous CFM rating is required of your air compressor.

We recommend increasing the CFM total you get from the highest rated tool (or the total number of highly rated tools that could be used at the same time) by 50 percent to ensure that you have adequate performance under the most demanding applications you may encounter. For example, if a ½” impact wrench requires 4 CFM at 90 PSI, select a compressor that delivers at least 6 CFM at 90 PSI.

Horsepower

The horsepower of a compressor isn’t directly connected to the performance of the air tools or delivery of air, but it is an important factor when deciding on what is the best 30-gallon air compressor to buy. Because a 30-gallon air tank is relatively big, it takes time to fill up the tank with compressed air (up to 10 minutes for some models). The higher the horsepower, the quicker the tank will be filled. However, you should pay attention to the CFM rating first before considering the horsepower rating. The best air compressor may not be the right one for you if it doesn’t deliver the CFM you require of it.

Single Stage or Dual Stage?

Dual-stage compressors tend to be more efficient, compressing air to a higher pressure (PSI) than single-stage compressors. This allows more air to be stored for future use while generating less heat, reducing wear and extending compressor life. Dual-stage compressors are good choices for continuous use in shops or to power multiple tools at once.

Other things to Consider

It would be difficult to buy the right 30-gallon air compressor for your needs without understanding these following features:

  • An oil-free pump reduces maintenance and does not mix oil into the compressed air. An oil pump tends to run quieter, cooler, and more durable. Moreover, an oil compressor weighs a lot more than an oil-free compressor and costs more as well.
  • A belt-drive compressor offers greater flexibility to adjust the airflow and pressure as needed. It is also less expensive to purchase and is easier to install and maintain than a direct-drive compressor. However, a direct-drive compressor has the ability to operate at lower temperatures and higher energy-efficiency.
  • Low-oil shutdown prevents downtime and costly repairs resulting from low oil levels
  • V-design cylinders typically run cooler that in-line cylinders. Heat is a compressors worst enemy.

What size generator to run a 30-gallon air compressor?

WEN 56682, 5500 Running Watts/7000 Starting Watts, Gas-Powered Portable Generator | Buy on Amazon

Most 30-gallon electric air compressors we’ve reviewed draw about 15 amps to 20 amps on 120V household current. Running these compressors off a generator you will need a generator at least 3000 running watts/6500 starting watts for the compressor needs on startup.

Manufacturers do not recommend using a generator to power your compressor. They claim air compressors can be seriously damaged by the generator’s sudden fluctuations in power. They will also deem this as improper use and will void any warranty on the compressor.
