Features 47kg heavy-duty construction for maximum reliability.
German-engineered ZIEHL-ABEGG construction with 47kg heavy-duty centrifugal design ensures reliable, long-term operation exceeding 10+ years in demanding industrial environments. Premium industrial-grade materials, precision-balanced centrifugal impeller optimized for 1860 RPM high-speed operation, reinforced motor components, and heavy-duty scroll housing guarantee exceptional lifespan for continuous operation in commercial and industrial applications requiring maximum reliability with three-phase power efficiency and robust performance under demanding operating conditions.
Optimized 1860 RPM high-speed operation provides exceptionally quiet performance for a heavy-duty industrial centrifugal fan, ideal for commercial buildings, industrial facilities, and applications where noise control is essential despite high rotational speed requirements. Advanced centrifugal aerodynamics with optimized impeller and scroll design minimizes turbulence and operational noise at elevated speeds. Precision balancing of the 47kg rotating assembly ensures smooth, vibration-free operation even at maximum speed output, reducing acoustic emissions in sensitive environments while maintaining efficient high-pressure airflow performance.
3.5KW power rating with efficient 5.60-4.40A current draw provides optimal energy efficiency for three-phase 380/480V high-performance applications requiring substantial airflow and pressure. Advanced three-phase motor design maximizes efficiency while delivering excellent airflow and cooling performance at 1860 RPM. Three-phase operation ensures superior torque characteristics, smooth high-speed operation, and compatibility with industrial power systems, offering optimal power utilization and reduced operating costs in commercial and industrial settings with demanding ventilation requirements.
Efficient centrifugal design at 1860 RPM generates substantial high-velocity airflow with excellent pressure development for demanding commercial and industrial applications. 70×70×50cm heavy-duty industrial design provides superior performance with excellent pressure characteristics at elevated speeds, making it ideal for applications requiring substantial airflow against significant system resistance in ducted ventilation systems, industrial cooling, and process applications where overcoming pressure loss is essential for system efficiency and heat dissipation in high-demand scenarios.
The GR50C-ZID.GG.CR heavy-duty high-speed centrifugal fan is engineered for demanding commercial and industrial applications requiring reliable, efficient three-phase 380/480V high-velocity airflow solutions with substantial power, minimal noise, and exceptional performance in pressure-critical environments with industrial power infrastructure.

A: The 47kg heavy-duty centrifugal construction with industrial-grade components optimized for high-speed operation provides exceptional durability exceeding 10+ years of continuous operation in demanding industrial environments. ZIEHL-ABEGG's German engineering excellence includes industrial-grade ball bearings specifically rated for heavy-duty high-speed centrifugal applications (minimum 70,000 hours), thermally optimized three-phase motor windings designed for continuous 3.5KW operation at 1860 RPM, reinforced scroll housing with extra-heavy-gauge materials to withstand extreme pressure forces at elevated speeds, and premium-grade electrical insulation rated for industrial voltage applications. This heavy-duty high-speed centrifugal fan delivers reliable performance in critical industrial applications with precision dynamic balancing and reinforced components handling substantial loads while minimizing mechanical stress at high rotational speeds.
A: The optimized 1860 RPM high-speed operation combined with advanced acoustic engineering in a heavy-duty platform provides exceptionally quiet performance for an industrial centrifugal fan. The centrifugal design with aerodynamically optimized impeller blades and carefully engineered scroll housing produces smooth airflow with minimal turbulence, resulting in lower aerodynamic noise despite high rotational speed. Precision dynamic balancing of the 47kg rotating assembly specifically tuned for 1860 RPM operation significantly reduces vibration and mechanical noise transmission. The 70×70×50cm heavy-duty construction incorporates advanced noise-damping features in the reinforced scroll housing, optimized airflow paths that minimize turbulence at high velocity, and vibration-isolating mounting options. Advanced three-phase motor technology with optimized magnetic circuits ensures smooth operation reducing electromagnetic noise at elevated speeds.
A: The 3.5KW power rating with three-phase 380/480V operation at 1860 RPM offers exceptional energy efficiency and performance for heavy industrial applications requiring high-velocity airflow. Three-phase operation provides superior efficiency compared to single-phase systems, with better power factor characteristics and smoother torque delivery for high-speed applications. The current draw characteristics (5.60A at 380V, 4.40A at 480V) indicate well-designed motor efficiency and optimal power utilization for the specific airflow and pressure requirements of heavy industrial applications. This makes the fan ideal for applications with demanding ventilation requirements, such as large industrial facilities with extensive ducted systems, manufacturing plants with high heat loads, and commercial buildings where energy efficiency must be balanced with high-performance cooling capabilities at elevated operating speeds in continuous duty cycles.
A: The GR50C-ZID.GG.CR with 70×70×50cm heavy-duty design, three-phase 380/480V operation, 3.5KW power, 47kg construction, and 1860 RPM high-speed operation provides unique advantages for heavy industrial applications. Key advantages include: 1) Heavy-duty construction (47kg) providing maximum durability for continuous industrial operation; 2) High-velocity airflow capability suitable for applications requiring rapid air movement and extreme pressure development; 3) Three-phase power efficiency for energy-conscious operation at elevated power levels; 4) Centrifugal design optimized for high-pressure applications with significant system resistance; 5) Compatibility with international industrial voltage standards (380V/480V).
