Bold: The bolded measurements indicate the smallest motor that can be used to obtain the shown airflow, with the given blade selection.
Note: Airflows are for reference only. Airflow was measured in the V-direction (discharge over motor). Airflow in the A-direction (intake over motor) is typically lower.
Other motor/blade combinations may be possible if higher flows are required at a duty point with low static pressure. Please consult ebm-papst Application Engineering to make this determination.
iQ Motor and Blade Selection Guide:
Chart below details the typical airflow (CFM) and input power (Watts) for available motor and blade combinations measured at free air.
