Fans Air Flow versus Static Pressure

ventilation fans can effectively operate at static pressures of up to 0.25 in water by delivering a cfm airflow rate similar to the cfm rate at much lower static pressures The performance of a fan is defined as the amount of airflow in cfm at a given static pressure.
