The "Initial Desired CFM Total" is how much air needs to be moved through a facility to ensure a comfortable environment. This rate of airflow is expressed as cubic feet per minute, or CFM. It can be found with the following equation.

  • CFM = (V x ACH)/60
  • CFM = Cubic Feet per Minute
  • V = Building volume
  • ACH = Air Changes per Hour in the building. Click Here to see the recommended air changes for your facility.
