Airflow before and after service on low setting
Summary: Airflow increased by an average 22% from 785 FPM to 985 FPM.
The graph below is high fan airflow measured in FPM sorted from low to high before the coil rejuvenation.
The red line shows that before service the high fan airflow ranged from 385 FPM to 1085 FPM. Average airflow was 785 FPM.
The blue line shows that after service the high fan airflow ranged from 569 FPM to 1400 FPM.
Overall the coil rejuvenation increased the airflow by an average 22% from before 785 FPM to after 985 FPM
