How Big a Compressor for Air Impact Wrench in 2022?
The size of air compressor you’ll need for your impact wrench will depend on a few factors, including the power of the wrench and the duty cycle. A 1/2″ impact wrench will require a much larger compressor than a 1/4″ impact wrench.
To determine the size of air compressor you’ll need, first calculate the CFM (cubic feet per minute) requirement of your impact wrench. To do this, multiply the power of the wrench by the duty cycle. For example, if you have a 1/2″ impact wrench that requires 6 CFM, and it has a duty cycle of 50%, you’ll need an air compressor that can deliver at least 12 CFM.
Once you know the CFM requirement of your impact wrench, you can choose an air compressor that meets or exceeds that number. Keep in mind that the size of the tank on the compressor will also be a factor in how long you can use the wrench before needing to stop and let the compressor catch up. A larger tank will allow you to use the wrench for a longer period of time before needing to stop.
If you’ll be using your impact wrench for extended periods of time, or if you have a high CFM requirement, you may want to consider a two-stage air compressor. A two-stage air compressor has a larger tank and can deliver more CFM than a single-stage air compressor. This type of compressor is typically more expensive, but it will be able to keep up with your demands more easily.
When choosing an air compressor for your impact wrench, make sure to consider the CFM requirement, duty cycle, and tank size to ensure you get the best performance for your needs.
