Professional 4.6/2.8kW centrifugal fan featuring dual-speed 1250/940 RPM operation with three-phase 400V compatibility. German-engineered by ZIEHL-ABEGG with massive 140kg heavy-duty robust construction for exceptional durability exceeding 10+ years, ultra-quiet performance, superior energy efficiency with dual-current 7.5/4.5A draw, and massive high-velocity centrifugal airflow for superior heat dissipation in the most demanding large-scale industrial applications . Article No: 133687.
German-engineered ZIEHL-ABEGG construction with massive 140kg heavy-duty industrial design ensures reliable, long-term operation exceeding 10+ years. Premium materials including reinforced steel housing, high-quality ball bearings, and precision manufacturing guarantee exceptional lifespan in the most demanding environments with minimal maintenance requirements . ZIEHL-ABEGG has over 100 years of engineering expertise, and their fans are designed for high durability and reliability in continuous operation .
Dual-speed 1250/940 RPM operation with advanced centrifugal fan design delivers exceptionally quiet performance for a fan of this massive size. Precision engineering, vibration-damping technology, and aerodynamic impeller optimization minimize noise, making it suitable for noise-sensitive industrial environments while maintaining powerful airflow .
Dual-power rating (4.6/2.8kW) with intelligent dual-current consumption (7.5/4.5A) provides exceptional energy flexibility and efficiency. This innovative design allows optimal operation at different power levels, significantly reducing energy consumption while maintaining excellent performance for continuous operation in the most demanding applications .
Dual-speed 1250/940 RPM operation combined with large-diameter optimized centrifugal impeller design generates exceptional directional airflow with volume capacity up to 35,000 m³/h and high static pressure . Superior air movement capabilities provide remarkable heat dissipation, making it perfect for the most demanding large-scale industrial applications requiring significant cooling performance in ducted systems .
The ZIEHL-ABEGG RG63N-VDK.7Q.1L is engineered for the most demanding heavy-duty applications across multiple industries requiring reliable, energy-efficient centrifugal airflow solutions .
Innovative dual-speed design provides exceptional operational flexibility for varying application requirements. The 940 RPM setting at lower power offers ultra-quiet, energy-efficient operation for normal conditions, while the 1250 RPM setting at 4.6kW delivers massive airflow up to 35,000 m³/h when maximum performance is needed . This allows for optimal energy usage and extended equipment life by operating at the most appropriate speed for current conditions .
Intelligent dual-current design provides outstanding energy efficiency with only 7.5A draw at full speed and just 4.5A at lower speed. This automatically optimizes power consumption based on operational requirements, minimizing costs and reducing electrical infrastructure needs for large-scale industrial 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, perfect for continuous operation in the most demanding environments .
140kg massive heavy-duty construction with robust dimensions provides exceptional stability and durability. German engineering ensures reliable performance in the most demanding large-scale applications with 10+ year lifespan and minimal maintenance requirements .

A: This fan utilizes a large-diameter optimized centrifugal impeller design combined with powerful dual-speed 1250 RPM operation at 4.6kW. The advanced aerodynamic impeller is engineered for maximum air movement efficiency, generating exceptional directional airflow up to 35,000 m³/h with high static pressure. This makes it one of the most powerful centrifugal fans in its class for large-scale industrial cooling applications .
A: The massive 140kg heavy-duty construction incorporates premium materials including reinforced steel housing, high-quality industrial bearings, and precision German manufacturing standards. The dual-speed operation also allows operation at lower speeds when full power isn't needed, reducing mechanical stress and extending component life. Every component is optimized for long-term reliability in the most demanding continuous operation environments with minimal maintenance requirements .
A: The dual-speed 1250/940 RPM operation provides exceptional flexibility: at 940 RPM/2.8kW, the fan operates at ultra-quiet levels with reduced energy consumption for normal conditions. When maximum cooling is required, the 1250 RPM/4.6kW setting delivers massive 35,000 m³/h airflow. This flexibility allows for optimal energy usage, extended equipment life, and adaptation to varying cooling demands throughout different seasons or operational conditions .
A: The RG63N-VDK.7Q.1L is widely used in heavy industrial ventilation systems, large central HVAC for factories and warehouses, power plant cooling, large data centers, industrial process cooling, and tunnel ventilation . Its massive airflow capacity and high static pressure make it ideal for any application requiring significant air movement in large ducted systems or through heat exchangers .
