Introducción del producto
The design of low-noise centrifugal fans meets the requirements of JB/T 8690-1998 Industrial Ventilation Fan Noise Limits. The raw materials are Q235A/B grade steel materials, and the air inlet is equipped with a silencer, which can reduce noise by 5-15 decibels. For environmental requirements, a customized solution is designed, making it a convenient way to load and unload centrifugal fans.
Panli Fan has ten years of manufacturing experience and has been awarded the title of "Top 100 Enterprises of Jiangsu Province". It has obtained more than 30 patent certifications, including substantive patents such as "An Imported Silencing Device for a Centrifugal Fan" and "An Exhaust Gas Collection Device for a Centrifugal Fan". Can optimize design and support specification customization.

Within 72 hours, you can come to the door to solve the problem, and professional technology will solve various problems encountered by users, ensuring worry free use.
A Low Noise Centrifugal Fan is developed to deliver high efficiency and airflow while minimizing acoustic emissions, making it ideal for environments where both performance and quiet operation are required. It operates on the same centrifugal principle as standard fans—air enters the impeller axially and is accelerated outward through the volute—but incorporates advanced aerodynamic and structural noise-reduction technologies.
The impeller is designed with backward-curved or airfoil blades, which significantly reduce turbulence and blade-pass frequency noise. The volute casing features a smooth curvature that minimizes airflow separation. Materials such as galvanized steel or stainless steel are used for structural integrity, and internal surfaces may include sound-absorbing linings or vibration-damping layers. The entire fan assembly undergoes precision balancing to eliminate mechanical resonance.
Low noise centrifugal fans often employ rubber or spring vibration isolators, flexible duct connections, and silencers at inlet or outlet sections. The bearings are lubricated with low-friction grease, and the motor can be mounted on a separate frame with acoustic isolation. Air performance is optimized through computational fluid dynamics (CFD) analysis, ensuring minimal aerodynamic loss. Energy-efficient motors, often compliant with IE3 or IE4 standards, further enhance quiet operation and reduce heat generation.
These fans are widely used in HVAC systems, laboratories, clean rooms, hospitals, food processing facilities, and electronic manufacturing workshops. Typical airflows range from 500 m³/h to 100,000 m³/h with pressures from 300 Pa to 3,000 Pa, depending on model size and speed. Combining high efficiency, low vibration, and minimal noise, low noise centrifugal fans ensure a comfortable and quiet working environment without sacrificing performance or reliability.
