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.
