How to Use This Chart?
- SCFM Column: Standard Cubic Feet per Minute, as defined by standard conditions.
- Temperature (°F): The actual inlet air temperature.
- Barometric Pressure (PSIA): Atmospheric pressure at your location.
- Actual Pressure (PSIA): The measured pressure entering the system.
- CFM Column: The converted value for cubic feet per minute based on input conditions.
Key Observations
- Higher Temperatures lead to slightly lower CFM values since warmer air is less dense.
- Lower Actual Pressure results in lower CFM values because the pressure differential reduces air movement.
The relationship between SCFM and CFM is linear under constant conditions but varies with changes in environmental factors. This chart provides a reference for quick conversions, but using a our online calculator with precise inputs is recommended for accuracy in real-world applications.
Key Differences Between SCFM and CFM
- Standard Conditions: SCFM considers standardized temperature and pressure.
- Real-World Accuracy: CFM accounts for actual operating conditions.
- Measurement Context: SCFM provides a baseline But CFM gives real-time data.
Most Common Use Cases
- Home Air Compressors: Typically use values around 10–20 SCFM at standard temperatures and pressures.
- Industrial Applications: Often range from 25–50 SCFM, depending on specific needs.
- Portable Compressors: Use lower SCFM, typically around 5–10 SCFM.
