• To get the desired air flow and external static pressure combination, use the setting value from the table. Using a setting value other
than that listed in the table will not provide the desired combination.
• Table data is based at 230V. Air flow rate varies according to voltage fluctuation.
Due to our policy of continuous product innovation, some specications may change without notication.
