OWB7040AL High Speed High Efficiency 12V Brushless DC Centrifugal Air Blower For Medical Device

Brushless DC Air Blower Features:

1: High speed, specialized high-speed ball bearing(NMB) offering long service life and lower noise

2: High pressure and airflow output by compact size design

3: High efficiency, much more efficient than brush motor blower

4: High reliability, specialized controller make the working more reliable

5: High intelligent, PWM speed regulation, positive inversion, PG signal feedback, intelligent controlling

Technical Parameters: 

Mechanical Size:

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?
