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.
