Understanding Air Compressor CFM
CFM (Cubic Feet per Minute) is a measure of the airflow capacity of an air compressor. Choosing the right CFM is essential for ensuring your tools operate efficiently and effectively.
How to Calculate Required CFM
The required CFM depends on the CFM requirements of your tools, the number of tools you plan to use simultaneously, and the usage factor. Here's the formula:
| Parameter | Formula | Description |
|---|---|---|
| Total CFM | Tool CFM × Number of Tools | Total CFM for all tools |
| Adjusted CFM | Total CFM × (Usage Factor ÷ 100) | CFM adjusted for usage percentage |
Common CFM Requirements
Here are some typical CFM requirements for common air tools:
| Tool | CFM Requirement |
|---|---|
| Air Ratchet | 2.5 - 5 CFM |
| Impact Wrench | 4 - 10 CFM |
| Spray Gun | 5 - 15 CFM |
| Air Sander | 6 - 20 CFM |
| Air Drill | 3 - 8 CFM |
Frequently Asked Questions
What happens if my compressor's CFM is too low?
If your compressor's CFM is too low, your tools may not operate efficiently, and the compressor may overheat or fail to keep up with demand.
How do I find the CFM requirement of my tools?
Check the tool's user manual or specifications label. Most tools list their CFM requirements.
Can I use multiple tools with one compressor?
Yes, but ensure the compressor's CFM rating meets or exceeds the combined CFM requirements of all tools used simultaneously.
What is the usage factor?
The usage factor is the percentage of time the tool will be in use. For example, if a tool is used 50% of the time, the usage factor is 50%.
