Best 10 Carefully-Picked Air Compressors For Impact Wrenches

An impact wrench is a power tool that uses the energy it has stored in a rotating mass to deliver high torque output with minimal exertion. You can use it for the repair and maintenance of automobiles and heavy equipment.

And while you can pair it with electric and hydraulic power, most people use air compressors to run their impact wrenches.

Air compressors are mechanical devices that use pressurized air to generate the power required to operate devices like impact wrenches.

Impact wrenches are all the rage today because you can use them to accomplish strenuous tasks without applying much in the way of effort. With the best air compressor for impact wrenches on hand, you can repair your vehicle, renovate your home, and fix your roof on your own without wasting money on an expensive contractor.

Admittedly, some people are not convinced that impact wrenches are as powerful as everyone says. In fact, some people have criticized them for being cumbersome and inconvenient. But such complaints are only true in situations where an impact wrench has been paired with the wrong air compressor.

You need the best air compressor to appreciate the simplicity and efficiency of an impact wrench. However, selecting the wrong air compressor for your project is very easy.

This is because the market is saturated with air compressors. And unfortunately, not all of them are suitable for an impact wrench. To find the right air compressor, you need to take variables such as the airflow and pressure into account, matching them to the needs of your impact wrench and the tasks you want to accomplish.

This is the only way to ensure that your impact wrench delivers on its promises. However, most people don’t know enough about impact wrenches to successfully match them with a suitable air compressor.

That is why this guide was created, to point you in the direction of an air compressor that will make effective use of the various gifts of your impact wrench.

Choosing the Right Air Compressor for Your Impact Wrench

As was noted above, finding the right air compressor is no easy task. There are too many brands on the market today, which is why you cannot afford to rush the selection process. Take as much time as you need to consider factors such as the following before you make your decision:

  • Single Stage VS Two-Stage

Do you want a single-stage compressor or a two-stage compressor? They are not the same things. A single-stage compressor compresses the air once. The two-stage compressor compresses the air twice. You can technically get by with a single-stage compressor.

However, two-stage units have a reputation for running cooler. They also have more CFM to offer. It is a question of your needs.

  • Duty Cycle

Have you seen an air compressor whose specs claim that it has a 50 percent duty cycle? That figure is important. It means that the compressor can run for five minutes continuously within any given ten-minute period.

The duty cycle is presented as a percentage and it will tell you the number of minutes that the compressor can operate within a ten-minute period. In other words, it shows you the amount of continuous work you can do.

Naturally, you want a compressor that offers you the highest duty cycle possible. While most people can get by with 50 percent, 75 and 100 percent are better. No one will stop you from exceeding the duty cycle.

However, doing so will jeopardize your air compressor, compromising the pump and motor. You will lower the lifespan of the unit.

  • Longevity

Most manufacturers won’t tell you how long their air compressor will last. They don’t want to publish an exaggerated number that will attract criticism from consumers if the air compressor fails to meet expectations.

The only way to determine the durability and life expectancy of an air compressor is to look at the reviews. The people who have used it will reveal to you the conditions it can withstand.

You can also use their testimonies to build a rough picture of the life expectancy of the unit. A compressor’s durability and lifespan are important because they will affect your decision where the price is concerned.

Some people are easily swayed by cheap air compressors. They do not realize that some compressors are sold at discounted prices because they don’t last long. You are better off purchasing an expensive air compressor with a strong reputation that will serve you for several years.

  • Tank

Where the tank is concerned, you should pay close attention to the size. It will tell you the amount of air the compressor can store. The size of the tank will determine the amount of continuous work you can do before refilling the tank. However, it will also affect weight.

Larger tanks are suitable for heavy-duty projects that do not require the air compressor to move. Hobbyists and homeowners are expected to prioritize smaller tanks associated with portable compressors.

  • Portability

The portability of an air compressor is determined by the size and weight. Your requirements where the size and weight are concerned will depend on the tasks you want to accomplish.

If you need a powerful compressor with a lot of air and your work doesn’t require the unit to move, you should buy the larger models that have to be bolted into the ground to prevent them from falling over.

But if your work requires frequent movement in and around the Jobsite, and you have to carry the air compressor from one Jobsite to another, you should prioritize the smaller, lighter units.

If you are determined to purchase larger, more powerful compressors, find models with wheels and handles.

  • Noise

A lot of air compressors are very loud and you cannot afford to use them indoors, not without deploying ear protection. They are best utilized in outdoor settings. Other compressors have quiet operations. You can use them without disturbing the people in the vicinity. But they are not always as powerful as their louder counterparts.

  • PSI

What is the air compressor’s maximum PSI? To work with a pneumatic tool, you need a minimum PSI of 125. The maximum PSI of your chosen compressor should match the air pressure requirements of your impact wrench.

  • Oil-Free VS Lubricated

Lubricated air compressors require oil. They are more powerful and they last longer but they are messy and they require significant maintenance. With oil-free models, you don’t have to concern yourself with oil leaks or maintenance, and neither are you expected to check the oil levels.

Unfortunately, oil-free compressors are not as durable. You have to compare and contrast the pros and cons of both oil-free and lubricated compressors to identify the model that suits your needs.

FAQ

Q.How Much Air Pressure Does an Impact Wrench Use?

ANSWER:When purchasing an air compressor, you should look for models that can generate at least 90 PSI.

Q.What is the Best Tank Size for an Impact Wrench?

ANSWER:You should get the biggest size possible without exceeding your size and weight preference. Small tanks are annoying because you have to keep stopping to refill them. You should target tanks of at least 20 gallons.

Q.What is the Best Air Flow Rate for an Impact Wrench?

ANSWER:It depends on several factors, including the drive diameter of the wrench and the tank volume. However, in many cases, you are encouraged to aim for 3-4CFM.

Q.Can You Pair an Air Compressor with a Generator?

ANSWER:It isn’t a good idea because the power provided by a generator tends to fluctuate. This will negatively affect the performance of your compressor.

Q.Are SCFM and CFM the Same?

ANSWER:CFM stands for ‘Cubic Feet per Minute’. It reveals the airflow rate at a specific pressure. SCFM stands for ‘Standard Cubic Feet per Minute’. It measures performance at a specific pressure and temperature.

Final Verdict

Based on the buying guide, you can probably tell that finding the best air compressor for impact wrench is no easy task. Fortunately, the list above has some of the most outstanding models in the business.

So you can save yourself some time by making your selection from the products above. Some are better than others. For instance, the Powermate Vx PLA4708065 is very powerful. But it is too heavy and the weight is focused on the top.

The Porter-Cable C2002 is lighter but it doesn’t have as much power. The Makita MAC5200 is balanced, small enough to carry from place to place but powerful enough to take on more strenuous tasks.

Of course, if power is your only concern, you cannot go wrong with the Industrial Air ILA4546065. As you can see, there is plenty of variety in this list for you to choose from.
