Quick Calculations: For every 1000 ft (305 m) of elevation increase over "standard conditions", ACFM demand increases by approximately 5%. However, air density will change with temperature and pressure, which is where a more scientific calculation, such as SCFM comes in handy. Example: A typical 1-ton air conditioner will generate 400 CFM of airflow. So, if your compressor has a Free Air Delivery of 9 CFM, it would take 9 minutes to fill up a gallon tank at 100 PSI. To calculate the airflow with an inlet pressure of 80 PSIG (5.5 BAR), the calculation is as follows: Model 3215 consumes 15 SCFM @ 100 PSIG (425 SLPM @ 6.9 BAR) and will consume 12.4 SCFM @ 80 PSIG (351 SLPM @ 5.5 BAR). SCFM vs. CFM Find the volume of the air compressor tank in gallons. The most common used in the United States is with the "sea-level" properties: Europeans normally use one ata and 0 oC as SCFM. SCFM differs from CFM mainly in that SCFM has these variables fixed. The formula for converting SCFM to ACFM is as follows: ACFM = SCFM [Pstd / (Pact - Psat )] (Tact / Tstd) Where: ACFM = Actual Cubic Feet per Minute. Too little pressure means the job wont get done. Refill the. We don't save this data. For more information about this conversion, click here. Step 1: Calculate the ratio of absolute inlet pressures. Hopefully, now the SCFM vs CFM relation is better understood. Knowing what each of them means will help us illustrate the main SCFM vs CFM differences: If you check the Ideal Gas Law, you can see why not all air (gas) is the same.
