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.
