Notes:
1. Do not use max pressure as working point, this point is not safe
since airflow is too small.
2. To add a filter onto the inlet can make the blower run longer
time.
3. The right impeller run direction is CCW.
Blower Features:
1. NMB ball bearing guarantee long life.
2. Compact size but output high pressure and airflow.
3. Very suitable for compact system or tools.
4. Can choose Junqi External driver board.
