The Versatile Workhorse for Industrial Ventilation
A cornerstone of efficient air movement, the medium-pressure centrifugal fan strikes an ideal balance between pressure capability and airflow volume. As one of the most widely used standards in industrial ventilation systems, it is engineered to move air and non-corrosive gases at temperatures below 80°C. Ideal for factory workshops, commercial buildings, and a wide range of process ventilation applications, it offers higher efficiency than high-pressure models in moderate-resistance systems. Its performance is reliably certified under the internationally recognized AMCA 210 standard, providing engineers with trusted data for accurate selection.
Engineered for Efficiency and Universal Application
The foundation of its reliable performance lies in an aerodynamically advanced backward-curved impeller, manufactured from high-quality steel. This design delivers optimal pressure (typically 800–3,000 Pa) while achieving operational efficiency exceeding 85%. Each impeller is precision-balanced to ISO 1940 G6.3 standards, ensuring smooth, low-vibration operation from initial startup. Available in both direct-drive (A-type) and belt-driven (C-type) configurations with adjustable outlet positions, the fan adapts seamlessly to various installation layouts. Extended-life, maintenance-sealed bearings are rated for more than 60,000 hours of service.

Proven Value in Diverse Settings
Consider its role in an automotive paint shop ventilation system. A No.8 Medium-pressure centrifugal fan, with a 15 kW motor at 1450 r/min, can deliver approximately 25,000 m³/h at 1200 Pa, effectively removing solvent vapors and overcoming duct and filter resistance for 24/7 operation. This same versatility and efficiency make it ideal for electronics cleanrooms, shopping mall air handling units, and chemical plant general exhaust. By combining adaptability with controlled energy consumption, this fan reduces long-term operational and maintenance costs, delivering both performance and economy.
