The flowbench is a machine that measures the airflow through the ports by sucking air thru like a vacuum cleaner. The vacuum gauges on the bench actually measure the resistance to the flow thru the ports, and the result is converted into CFM. That means "how many Cubic Feet of air will flow through the port per Minute."
