The facts:
6 diameters from 355mm to 630mm, with 7,500 Pa static pressure increase possible; high total efficiencies achieved as a result of the optimized impeller / scroll and built-in high efficiency IEC motor.
By offering three blade diameter options for each impeller diameter, multiple operating points can be achieved without the need for speed regulation.
As a consequence, high efficiency matched with good economy, every day.
