Professional dual-speed centrifugal fan engineered by EBMPAPST for exceptional durability (10+ years), whisper-quiet operation, energy-efficient 0.47/0.67A current draw, and high-volume airflow delivering superior heat dissipation for industrial and commercial applications. Motor No: M4E074-DF.
German-engineered by EBMPAPST with robust 3.7kg 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.
Dual-speed 1430/1670 RPM operation with advanced centrifugal fan design delivers exceptionally quiet performance across both speed settings. Precision engineering, vibration-damping technology, and aerodynamically optimized impeller minimize noise, making it ideal for noise-sensitive environments.
Dual-power rating (105/150W) with energy-efficient dual-current consumption (0.47/0.67A) provides exceptional energy flexibility. This innovative design allows optimal operation at different power levels, significantly reducing energy consumption while maintaining excellent performance.
Dual-speed 1430/1670 RPM operation combined with optimized centrifugal impeller design generates powerful directional airflow with excellent volume capacity and high static pressure. Superior air movement provides remarkable heat dissipation, perfect for industrial applications requiring significant cooling performance.
The EBMPAPST R4E310-AF12-05 is engineered for versatile applications across multiple industries requiring reliable, energy-efficient centrifugal airflow solutions.
Innovative dual-speed design provides exceptional operational flexibility for varying application requirements. The 1430 RPM setting at 50Hz offers energy-efficient operation for normal conditions, while the 1670 RPM setting at 60Hz delivers significantly enhanced airflow and static pressure when increased performance is needed.
Intelligent dual-current design provides outstanding energy efficiency with only 0.47A draw at 1430 RPM and 0.67A at 1670 RPM. This automatically optimizes power consumption based on operational requirements, minimizing costs and reducing electrical infrastructure needs.
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.
3.7kg compact construction with 38×38×30cm dimensions provides easy installation in tight spaces. German engineering ensures reliable performance with 10+ year lifespan and minimal maintenance requirements.
