7: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.
