Comparison

7 blades design vs 5 highly profiled blades

Compared to a conventional impeller, the 5 blades design is optimized for high-airflow, low-static-pressure operation. This makes it ideally suited for data center cooling, where energy efficiency is crucial.

Airflow Range

From compact 250 mm impellers to high-performance 630 mm units, the SR range delivers exceptional airflow capacity seamlessly from 100 to 29 000 m³/h

Manufacturing

3D Printing

All our prototypes are rapidly manufactured in-house using our dedicated 3D printing room for efficient design validation and performance development.

Geometry Verification

To ensure that the shape of our fans is as designed, we regularly test their geometry using the latest 3D scanning techniques.

Life cycle and overspeed destructive tests

Our impellers undergo a 100,000-cycle start-stop test and a destructive overspeed test to verify material fatigue resistance and structural integrity, confirm safety factors and support the development of future designs.

Fan Impeller welding

Every impeller is laser welded to achieve perfect structural integrity and uncompromised acoustic performance.

Mass production of impellers

Automated production. Unified technological process. Full performance repeatability.

Precise assembly of each Impeller

Every impeller is carefully assembled and inspected to ensure precise geometry, structural consistency, and flawless operation before the next stage of production. Attention to all manufacturing standards guarantee reliable performance and long-term durability.

High-standard EC Motors
