📄 DOWNLOAD DATASHEETGerman-engineered by ZIEHL-ABEGG with robust 18kg construction ensures reliable operation exceeding 10+ years. Premium materials, high-quality ball bearings, and precision manufacturing guarantee exceptional lifespan in demanding environments with minimal maintenance requirements.
Advanced centrifugal fan design delivers exceptionally quiet performance at optimized 900 RPM. Precision-balanced impeller, vibration-damping technology, and aerodynamically optimized housing minimize noise, making it ideal for noise-sensitive environments like hospitals, offices, and residential areas.
Remarkable energy efficiency with ultra-low power consumption of only 160W (0.16kW) and intelligent dual-current draw (0.37A at 50Hz / 0.20A at 60Hz). Significantly reduces operational costs for continuous 24/7 operation while maintaining exceptional performance.
900 RPM optimized operation combined with advanced centrifugal impeller generates powerful, high-static-pressure airflow with exceptional volume capacity. Superior air movement provides remarkable heat dissipation for industrial equipment and HVAC systems.
The ZIEHL-ABEGG RH40M-6DK.4A.1R is engineered for versatile applications across multiple industries requiring reliable, ultra-energy-efficient centrifugal airflow solutions.
The ultra-efficient 160W (0.16kW) motor delivers exceptional airflow performance while maintaining outstanding energy efficiency. This advanced motor design provides optimal power-to-airflow ratio, ensuring maximum cooling capacity with minimal energy consumption for continuous operation applications.
Advanced three-phase 400V motor provides smooth, efficient power delivery with superior reliability for industrial applications. Three-phase technology offers better power factor, smoother torque delivery, and higher efficiency compared to single-phase alternatives.
Intelligent dual-current design draws only 0.37A at 50Hz and 0.20A at 60Hz, providing outstanding energy savings across different frequencies. This automatically optimizes power consumption based on operational requirements, minimizing energy costs.
18kg robust construction with 46×46×35cm dimensions provides exceptional stability and durability. German engineering ensures reliable performance with 10+ year lifespan and minimal maintenance requirements.
