10+ Years Industrial Durability
German-engineered by ZIEHL-ABEGG with robust 4.5kg 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 1260/1330 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 (0.14/0.17kW) with ultra-low dual-current consumption (0.60/0.76A) 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 1260/1330 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.
Industry Applications
The ZIEHL-ABEGG RH31L-4EP.WD.1R is engineered for versatile applications across multiple industries requiring reliable, energy-efficient centrifugal airflow solutions.
Advanced Technical Features
Dual-Speed 1260/1330 RPM Operation
Innovative dual-speed design provides exceptional operational flexibility for varying application requirements. The 1260 RPM setting offers ultra-quiet, energy-efficient operation for normal conditions, while the 1330 RPM setting delivers enhanced airflow and static pressure when increased performance is needed.
Intelligent 0.60/0.76A Dual-Current Design
Intelligent dual-current design provides outstanding energy efficiency with only 0.60A draw at 1260 RPM and 0.76A at 1330 RPM. This automatically optimizes power consumption based on operational requirements, minimizing costs and reducing electrical infrastructure needs.
Single-Phase 230V Convenience
Standard single-phase 230V operation provides easy integration into existing electrical systems without requiring three-phase power infrastructure. Perfect for commercial, residential, and light industrial applications where three-phase power is not available.
Compact 4.5kg Lightweight Construction
4.5kg lightweight yet robust construction with 36×36×35cm dimensions provides easy installation and excellent portability. German engineering ensures reliable performance with 10+ year lifespan and minimal maintenance requirements.
