The conversion from ACFM to ICFM can be expressed as, ICFM = ACFM (Pact / Pf) (Tf / Tact) (2), Pf = Pressure after filter or inlet equipment (psia), Tf = Temperature after filter or inlet equipment (oR). However, air density will change with temperature and pressure, which is where a more scientific calculation, such as SCFM comes in handy. For SCFM-part, we know that this AC will generate 400 SCFM of airflow. In systems with vacuum pumps, blowers, compressors, and heat exchangers, air pressure and temperature are constantly changing, which means the actual volume flow is changing. To calculate the actual pump capacity required, we first make the conversion to ACFM based on 24" Hg. Insert pressure.
