Knowing your primary applications helps you decide between piston compressors (great for intermittent use) and rotary screw compressors (better for continuous operation).
Air flow is measured in cubic feet per minute (CFM), and pressure is measured in pounds per square inch (PSI). Different tasks require different levels:
| Application | Typical PSI Range | Typical CFM Range |
|---|---|---|
| Bike tires | 30-50 PSI | 1-3 CFM |
| Car tires | 30-60 PSI | 2-5 CFM |
| Framing nailer | 70-120 PSI | 2-4 CFM |
| Brad nailer | 70-90 PSI | 0.5-1 CFM |
| Car painting | 40-60 PSI | 4-6 CFM |
| Sandblasting | 90-120 PSI | 6-10+ CFM |
| Sprinkler system | 30-40 PSI | 1-2 CFM |
| Cleaning dust and debris | 60-90 PSI | 3-5 CFM |
| Pneumatic tools and air tools | 70-120 PSI | 4-8 CFM |
Ensure the compressor you choose can deliver the required PSI and CFM simultaneously. Oversizing slightly can prevent strain and improve longevity.
Think about your long-term needs. Will you add more tools? Increase production? If so, select a compressor with extra capacity or one that can be upgraded. For example, a rotary screw compressor with a variable speed drive (VSD) can adjust output as demand changes, saving energy and accommodating growth.
