You might be wondering what size air compressor do I need to use an impact wrench. Although air compressors come in a variety of sizes, their ability to power your impact wrench is usually determined by the compressor’s capacity. In this article, we’ll show you how to determine your impact wrench’s air requirements so you can find the right air compressor.
The first thing to check is if your impact wrenches task requires constant or occasional use of your compressor. If you just need your impact wrench on occasion, a small compressor will suffice. But, if you need it on a regular basis, the compressor must have the discharge capacity that impact wrenches require.
In a non-assembly line context, an impact wrench is likely to be used for significantly less than half of the time, drawing the full CFM rating.
To use an impact wrench, what size air compressor do I need?
The size of the air compressor required for an impact wrench is usually determined by the impact wrench’s size. For a 12-inch impact wrench, you’ll need a 4-5 CFM at 90 PSI air compressor.
For example, a 1′′ drive impact wrench requires 10 CFM at 90 PSI, a 12″ drive requires 4 CFM at 90 PSI, and a 38″ drive requires 3 CFM at 90 PSI.
Most impact wrenches have a 12″ drive, which means you’ll be getting around 4 to 5 CFM at 90 PSI.
Other variables, on the other hand, will decide the size of the air compressor you’ll require. The type of project, the impact wrench, the power source, the quantity of space available, and the position where it will be used are all factors to consider.
How to Determine the Size of an Air Compressor Tank and the Air Requirements for an Impact Wrench
Two additional major factors influence the size of your air compressor. These are some of them:
* Air requirements for impact wrenches
* Size of the compressor tank
How to Determine How Much Airflow Your Impact Wrench Requires
Cubic Feet per Minute (CFM) is a unit of measurement for airflow (CFM). In general, the air compressor’s CFM should fulfill the impact wrench’s minimum CFM rating. As a result, CFM is frequently mentioned in terms of the amount of pressure (PSI) required to operate an impact wrench. CFM at 90 PSI is the most common example.
We just need to measure the air compressor’s minimum CFM rating because the impact wrench’s suggested CFM is set by the manufacturer. To do just that, multiply the CFM of the impact wrench by 1.5.
For example, if your impact wrench has a 4CFM airflow rating, the Air Compressor CFM = 1.5 x 4CFM, resulting in at least 6CFM of airflow from the compressor.
However, for impact wrenches, you can select the best one from the Barbershop air compressor list because these air compressors produce significantly less noise and are of high quality.
How to Calculate the Required Tank Size for an Air Compressor
Now that you know how much CFM the air compressor has to produce to operate your impact wrench, you can measure out how big the tank needs to be to accommodate that airflow.
Tanks for air compressors can hold up to 80 gallons. The larger the tank, the longer the compressor will be able to power the impact wrench before producing more compressed air. Because impact wrenches, unlike sanders and power tools like grinders, don’t require a steady supply of air, you’ll need a smaller tank. So, an 80-gallon air compressor is most powerful to run an impact wrench.
Simply multiply your impact wrench’s suggested CP by 6 to get the minimum tank size. For instance, if you have an impact wrench with a 4CFM, the size should be:
At least a 24-liter air compressor tank = 4CFM x 6. This is only an estimate, and we recommend going with a slightly larger tank just to stay safe.
Other Considerations in Choosing the Right Air Compressor Size
There is no such thing as a universal air compressor for impact wrenches. Other aspects to consider while choosing an air compressor for your impact wrench are listed below:
Type of Project
The amount of the air compressor needed to power the impact wrench will undoubtedly be determined by the type of project you’re working on. A stronger air compressor, such as the California Air Tools 8010 compressor, is required for high-torque operations like huge construction projects, car repair, or assembly projects.
A smaller air compressor will suffice for simple applications such as house maintenance or DIY projects.
Size of Impact Wrench
The compressor size will vary depending on the size of the impact wrench you have.
In comparison to a 1/2-inch and 14-inch drive, a 1-inch drive will require an air compressor with a larger tank and more airflow.
Amount of Space
If you aren’t working on any jobs that require high-torque impact wrenches, you should think about how much storage space you have. If you’re short on room, a smaller air compressor, such as a pancake air compressor, would be a better option.
On the other hand, if you have plenty of storage and require a larger tank, a larger compressor is the way to go. Keep in mind, that a compressor’s size does not always determine its air output. A compact air compressor, for example, may have a higher air output than a larger air compressor.
Your Workplace
As inconsequential as it may appear, the location from which you will be operating may influence the size of the air compressor you want. If you simply work in one location, such as a garage, a large air compressor will be sufficient.
If you’re moving from one position to another, though, a smaller, lighter air compressor that’s easy to transport may be preferable. Depending on the type of stationary workplace, a large or small air compressor will be necessary.
Is the Size of the Air Compressor Important?
Some manufacturers are now concentrating their efforts on manufacturing air compressors that are tiny and light while still providing adequate power. Most manufacturers, on the other hand, still measure a compressor’s power by its size.
As a result, estimating an air compressor’s power just based on its size is challenging. However, the following four factors can help you determine whether a compressor is powerful enough:
* Horsepower is a measure of how powerful something is (HP)
* CFM (cubic feet per minute) — The amount of airflow produced by the air compressor
* Pounds per Square Inch (PSI) – Airflow pressure
* Liquid capacity of the tank in liters
This information is normally found in the air compressor’s user handbook or on a sticker.
