5.2 Speed Controller Installation
The included speed controller comes with mounting screws, allowing it to be securely attached to a surface near the fan or in an easily accessible location. The controller is pre-wired with a power plug for convenience.
6. Operating Instructions
6.1 Adjusting Fan Speed
The inline variable speed controller allows you to adjust the fan's speed and turn it on or off. Turning the knob will increase or decrease the fan speed, optimizing airflow and noise levels for your specific application. The speed range includes low, medium, and high thresholds.

6.2 Airflow Direction
The fan is designed to boost airflow in a specific direction. Ensure the fan is installed with the airflow arrows pointing in the desired direction of air movement within your duct system.
7. Maintenance
The AC Infinity RAXIAL S8 fan is designed for minimal maintenance. Its balanced steel blades spin using permanently lubricated dual-ball bearings, eliminating the need for regular lubrication. Periodically inspect the fan and ducting for any debris accumulation that might obstruct airflow and clean as necessary.
8. Troubleshooting
- Fan not operating: Check if the power plug is securely connected and the speed controller is turned on. Ensure there is power to the outlet.
- Reduced airflow: Verify that the fan is installed in the correct direction (check airflow arrows). Inspect ducting for any blockages or leaks. Ensure the fan speed is set appropriately.
- Excessive noise: Adjust the fan speed to a lower setting. Check for any loose connections or debris inside the fan or ducting. Ensure the fan is securely mounted to minimize vibration.
