Jiuzhou Puhui Launches Upgraded 4-72 Centrifugal Fan with Multiple Motor Options for Enhanced Efficiency

The 4-72 series is renowned for its high efficiency, low noise, and wide pressure curve, making it ideal for indoor ventilation and air exchange in factories, underground garages, shopping malls, hotels, stadiums, and other large buildings. The key upgrade focuses on motor compatibility, providing multiple power options (from 0.75kW to 7.5kW) with comprehensive performance data tables covering rotation speed, airflow volume, static pressure, and more. This allows precise selection based on specific project requirements, reducing energy waste caused by over- or under-powered configurations.

Key Benefits of the Upgraded 4-72 Series:

• Flexible motor configurations to meet diverse airflow and pressure needs.
• Improved overall energy efficiency through better motor-impeller matching.
• Maintained low-noise operation and stable performance across different motor options.
• Faster customization and delivery thanks to standardized designs.

“In the context of China’s dual-carbon goals and the green transformation of industry, customers demand higher efficiency and adaptability from ventilation equipment,” said a technical lead at Jiuzhou Puhui. “This motor upgrade reflects our commitment to continuous innovation, helping clients build more efficient and reliable ventilation systems.”
