Designed for continuous, heavy-duty industrial duty, our single inlet backward curved centrifugal fan series engineered with a non-overloading horsepower curve, delivering high static efficiency and substantial energy savings compared to forward-curved alternatives. Operating across a medium-pressure performance envelope, this industrial centrifugal blower is a core air-moving solution for modern environmental engineering, HVAC ventilation, and process air systems.
Each fan system is built around a heavy-gauge welded steel volute casing and a precision-engineered backward-inclined impeller. By converting rotational kinetic energy into fluid pressure through optimized air foil geometries, the impeller generates low-turbulence airflow while reducing overall noise levels.
To ensure long-term mechanical reliability under demanding industrial conditions, every rotating assembly undergoes strict dynamic balancing in accordance with ISO 1940 (AMCA 204) standards prior to factory dispatch.

As a fundamental component in industrial air pollution control and ventilation infrastructure, our backward-curved centrifugal exhaust fans are deployed across diverse sectors:
Air Pollution Control & Dust Collection Systems: Serves as the primary draft source for baghouse dust collectors, cyclone separators, and wet scrubbers.
Industrial Furnace & Boiler Systems: Handles combustion air supply, forced draft (FD), and induced draft (ID) air circulating in kilns, ovens, and thermal processing equipment.
Industrial Exhaust & Material Transport: Efficiently extracts flue gas, chemical fumes, oil mist, and non-fibrous dust particles in metallurgical, chemical, and cement plants.
HVAC & Commercial Facility Ventilation: Provides reliable supply and return air for large-scale warehouse ventilation, underground parking exhaust, and cleanroom pressurized systems.
Our medium-pressure centrifugal fans are manufactured with modular structural components to allow seamless field integration and straightforward maintenance:
Aerodynamic Inlet Cone (Collector): Smoothly accelerates incoming air into the impeller throat to minimize inlet losses and turbulence.
Robust Volute Casing: Fabricated from Q235/Q345 carbon steel, SS304/SS316 stainless steel, or coated with anti-corrosion epoxy, designed according to GB/T 1236 (equivalent to ISO 5801).
Heavy-Duty Shaft & Bearing Assembly: Premium pillow block or monolithic bearing housings equipped with oil/grease lubrication, labyrinth seals, and temperature monitoring ports for 24/7 continuous operation.
Flexible Drive Configurations: Choice between direct-coupled drives for maximum transmission efficiency or belt/pulley drives for versatile speed adjustment.
