Wiring Diagram:
Notes:
1.Do not use max pressure ad working point,this point is not safe since airflow is too small
2.To add a filter onto the inlet can make the blower run longer time
3.The right impeller run direction is CCW
Blower Performance:
OWB7040AL-12V blower can reach maximum 19m3/h airflow at 0 kpa pressure and maximum 5.5kpa static pressure. It has maximum output air power when this blower run at 3kPa resistance if we set 100% PWM. It has maximum efficiency when this blower run at 3.6kPa resistance if we set 100% PWM. Other load point performance
refer to below P-Q curve
FAQ:
Can we connect this centrifugal air blower directly onto power source?
