10+ Years Industrial Durability
German-engineered by ZIEHL-ABEGG with robust 7kg 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.
Ultra-Quiet Dual-Speed Operation
Dual-speed 1340/1060 RPM operation with advanced centrifugal fan design delivers exceptionally quiet performance across both speed settings. Precision-balanced impeller, vibration-damping technology, and aerodynamically optimized housing minimize noise, making it ideal for noise-sensitive environments.
Energy Efficient Dual-Power Design
Dual-power rating (0.48/0.31kW) with ultra-low dual-current consumption (0.85/0.49A) provides exceptional energy flexibility and efficiency. This innovative design allows optimal operation at different power levels, significantly reducing energy consumption while maintaining excellent performance.
High-Volume Centrifugal Airflow
Dual-speed 1340/1060 RPM operation combined with optimized centrifugal impeller generates powerful directional airflow with excellent volume capacity and high static pressure. Superior air movement provides remarkable heat dissipation, making it perfect for industrial applications requiring significant cooling performance in ducted systems.
Industry Applications
The ZIEHL-ABEGG RH40M-VDK.4C.1R is engineered for versatile applications across multiple industries requiring reliable, energy-efficient centrifugal airflow solutions.
Advanced Technical Features
Dual-Speed 1340/1060 RPM Operation
Innovative dual-speed design provides exceptional operational flexibility for varying application requirements. The 1060 RPM setting offers ultra-quiet, energy-efficient operation for normal conditions, while the 1340 RPM setting delivers enhanced airflow and static pressure when increased performance is needed.
Intelligent 0.85/0.49A Dual-Current Design
Intelligent dual-current design provides outstanding energy efficiency with only 0.85A draw at 1340 RPM and 0.49A at 1060 RPM. This automatically optimizes power consumption based on operational requirements, minimizing costs and reducing electrical infrastructure needs.
Three-Phase 400V Industrial Power
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.
Compact 7kg Industrial Construction
7kg lightweight yet robust construction with 40×40×25cm dimensions provides excellent stability and easy installation. German engineering ensures reliable performance with 10+ year lifespan and minimal maintenance requirements.
