Why is the airflow too low in my ZIEHL-ABEGG ECblue BASIC-MODBUS Fan?

If the airflow from your ZIEHL-ABEGG Fan is too low, consider the following possible causes: * **Fan Speed:** The fan may be turning too slowly. See the section "Fan turns too slowly" for troubleshooting steps. * **Blocked Airways:** Check for any obstructions in the air passages, such as blocked supply or exhaust air vents and filters. Refer to the section "Impeller blocked or dirty" for guidance. * **Pressure Loss:** The pressure loss might be different than what was initially planned. Review the fan selection to ensure it matches the requirements.
