6: Attentions
1: Do not working under the max air pressure, the air flow is too small at max air pressure, and it's not safe for using.
2: Add a filter attach to the intake makes the blower bearing longer service life.
3: The correct rotation direction is CCW
4: Do not use the blower in High temperature ,high humidity, high magnetic fields
5: Please use suitable power supply for the blower.
FAQ:
Can you design a new blower fan if we give you target performance?
Yes, we offer ODM service for both blower fan and controller board
Can we connect this centrifugal air blower directly onto power source?
