Web5 jan. 2024 · Measure how far in inches the card swings inward to get a sense of the fan’s airflow. The rough airflow measurements for different inches are: 25 cfm for 1.5 inches (3.8 cm) 35 cfm for 2 inches (5.1 cm) 48 cfm for 2.5 inches (6.4 cm) CFM stands for “cubic feet per minute,” which is how airflow is measured. WebVacuum is a negative gauge pressure, usually referenced to the existing standard barometric pressure where the equipment will operate. This means vacuum is a differential reading between the surrounding atmospheric pressure and the …
