The RUCK AL 900 D4 04 is an inline cased axial fan designed for general industrial and commercial ventilation applications. It is part of the RUCK AL series and features a 900mm axial impeller developed with CFD-optimised aerodynamics to ensure efficient airflow performance.
The fan is equipped with a 4‑pole, 3‑phase IE3 efficiency motor suitable for frequency-controlled operation, allowing adjustable airflow while maintaining energy efficiency. The housing is weight-optimised and finished with a powder-coated surface for durability in standard ventilation environments.
The RUCK AL 900 D4 04 is suitable for conveying air and similar media with temperatures up to 60°C during continuous operation. Its design exceeds current ErP efficiency requirements by approximately 15 – 20%, making it appropriate for installations requiring energy regulation compliance.
