Product Description

Product Description4-79 Series: High-Efficiency General Purpose Centrifugal Fan The 4-79 fan belongs to the medium-pressure centrifugal category. It is engineered to handle clean air or non-spontaneous, non-corrosive gases with a dust content of less than 150 mg/m³. Its signature volute-shaped casing and backward-curved blades allow it to move massive volumes of air while overcoming moderate system resistance.Core Product Features
Superior Aerodynamic Efficiency: The impeller features backward-curved blades that have been optimized through fluid dynamics simulation. This design ensures high mechanical efficiency, reducing energy consumption even during long-term continuous operation.
Low Noise & Minimal Vibration: Each impeller undergoes rigorous static and dynamic balancing (G6.3 or higher). Combined with a heavy-duty reinforced housing, this ensures whisper-quiet operation and prevents mechanical fatigue.
Robust Volute Casing: The shell is constructed from high-quality carbon steel using advanced welding and flanging processes. The aerodynamic "snail" shape efficiently converts kinetic energy into static pressure.
Versatile Drive Configurations: * Type A: Direct drive (impeller mounted on the motor shaft) for a compact footprint.Type C/E/D: Belt or coupling drives, allowing for adjustable speeds and protection of the motor from high-temperature or dusty airflows.
Customizable Outlet Angles: The discharge outlet can be adjusted to various angles ($0^\circ$, $90^\circ$, $180^\circ$, etc.) to accommodate different ducting layouts and installation constraints.
High-Grade Motor Integration: Equipped with premium copper-wire induction motors (IP54/IP55) that offer stable performance and overload protection.
