How do air compressors work?
An air compressor works by using mechanical energy to compress air into a tank, which increases the air pressure and allows it to be stored for later use.
When it is turned on, the air is drawn into the inlet valve and the pump. As the pump runs, it compresses the air. The air increases the pressure inside the air compressor tank, and the outlet valve regulates the flow of air from the tank to the tool being used.
The compressed air can then be used to set the inflated tires or as a source of breathable air in diving and other applications.
The air is released from the compressor tank through a valve and used as needed, with the tank being refilled as the air is used.
The advantages of using an air compressor
An air compressor is crucial in powering an impact wrench, allowing it to provide the necessary air pressure and flow for fastening and unfastening tasks.
Before we start talking about which air compressor to choose, let’s discuss what advantages an air compressor can have.
Increased efficiency
- An air compressor provides the consistent and reliable flow of air that an impact wrench needs to perform its job effectively.
- This can save time and effort and increase efficiency, especially for heavy-duty tasks.
Increased portability
- An air compressor is more portable than an electrical outlet and can be taken to job sites and used in remote locations, giving you the freedom to work anywhere.
Longer tool life
- An air compressor can help your impact wrench last longer by giving it the proper air pressure and flow, which prevents it from being overworked or destroyed by insufficient power.
More profitable
- Over time, this can save you money compared to buying a few battery-powered impact wrenches and the cost of replacing batteries.

How to select an air compressor
When you think about what size air compressors should be, you should consider several factors. Without forgetting these factors and following them, you can succeed in choosing a compressor, ensuring reliable and efficient work, and making your work easier and more productive.
CFM (cubic feet per minute) requirement
CFM can be explained as how much air it can produce in one minute.
This is one of the important elements that show how good the compressor is.
Be sure of the rated power of your air compressor and that it meets the CFM requirements for your business.
PSI (pounds per square inch) requirement
It has the same value as CFM.
PSI measures how much air can be placed and compressed in a certain space
More than half of air compressors require in the range of 90 and 120 PSI values. However, it’s important to check the specific minimum requirement, to be sure.
Type of work
Which job you will do will also affect the air compressor’s size.
A smaller air compressor is ideal for light tasks. While for more complex work, a larger air compressor is needed.
Budget
The capacitance of the air compressor can also affect the cost.
Because of this, looking at the size, ask yourself whether this price is affordable or not.
A larger air compressor tank requires you to spend a lot of money. However, compared to purchasing a small air compressor, you will be confident in the power of your compressor, and you will not need to purchase an additional one.
Power source
Decide which type of air compressor you want to have: gas or electric.
Electric air compressors are silent and more convenient.
However, compressors with gas sources are more transportable and can be used in remote locations.
Recommendations for how to choose an air compressor
Guidelines to follow:
- Choose an air compressor with a CFM value that satisfies or exceeds the impact wrench’s CFM specifications.
- Pick a compressor whose nominal PSI value is equal to or greater than the needed PSI value.
- Give preference to an air compressor with a larger tank.
Conclusion
Thus, an air compressor is a very important choice that needs to be carefully discussed.
The first thing you need to know is to look at the CFM and PSI scores of air compressors and give preference to them which have better scores.
In addition, make sure that the container is of sufficient size to meet your requirements, and be able to find the appropriate space for it. Its size shows how often it is required to stop and start refueling with air, which can affect its effectiveness.
If you are planning continuous use, a larger tank is preferable. Also, don’t forget about the guides and recommendations we mentioned.
Final words
