Operation Guidelines
- Do not operate at maximum air pressure as airflow becomes minimal and unsafe
- Install intake filter to extend bearing service life
- Correct rotation direction is counter-clockwise (CCW)
- Avoid use in high temperature, high humidity, or strong magnetic field environments
- Use appropriate power supply matching blower specifications
- Contact manufacturer for compatible driver/controller units
