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.

6: Contact us for suitable driver/ controller for this blower.
