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?
This blower fan is with BLDC motor inside and it needs a controller board to run.
What kind of power source shall we use to drive this blower fan?
Generally, our customers use 24vdc switching power supply or Li-on battery.
Do you also sell controller board for this blower fan?
Yes, we can supply adapted controller board for this blower fan.
How to change impeller speed if we use your controller board?
You can use 0~5v or PWM to change speed. Our standard controller board is also with a potentiometer to change speed conveniently.
What is the MTTF of this centrifugal air blower?
MTTF of this centrifugal air blower is 20,000+ hours under 25 C degree.
