Engineered for continuous, heavy-duty industrial air handling, our Backward-Curved Single-Inlet Centrifugal Fan Series provides stable volumetric air delivery and medium-to-high static pressure across dust extraction loops, industrial furnaces, baghouse filtration systems, and environmental protection lines. Designed with a non-overloading backward-curved impeller, these fans maintain maximum fluid efficiency and lower power consumption under varying system resistance.

Manufactured in strict alignment with both Chinese national standards (GB/T 1236) and international benchmarks (ISO 5801 / AMCA 210), every fan unit undergoes factory dynamic balancing and vibration spectra inspection to ensure reliable 24/7 operation in harsh industrial environments.
Aerodynamic Performance Standards: Tested and rated in accordance with ISO 5801 and AMCA 210 / AMCA 300 standards (equivalent to Chinese GB/T 1236-2017 for industrial fan performance testing).
Dynamic Impeller Balancing: Impeller assemblies are dynamically balanced to ISO 1940 / ISO 21940 Grade G2.5 (GB/T 9239 compliant) to eliminate shaft vibration and extend bearing operational life.
Motor & Electrical Safety: Equipped with heavy-duty IEC-standard / GB 18613 IE3/IE4 high-efficiency motors, featuring IP55 weather protection, Class H/F insulation, and broad-voltage options (200V-480V, 50Hz/ 60Hz) for global grid compatibility.
Welding & Structural Integrity: Casing and structural skid welding meet ISO 5817 Level C / AWS D1.1 structural steel welding specifications.

Non-Overloading Backward-Curved Impeller: Constructed from high-tensile Q355B carbon steel (or optional 304/316L stainless steel). The backward-curved blade geometry resists particulate accumulation while preventing motor overload as system static pressure fluctuates.
Aerodynamic Volute Housing & Inlet Cone: Continuously welded heavy-gauge volute casing with a smooth spun inlet collector (convergent inlet cone) designed to minimize intake air turbulence and boundary-layer friction losses.
Drive Systems & Shafting Assemblies:
Type A (Direct Drive): Compact footprint with minimal power transmission loss.
Type C / E (Belt Drive): Flexible speed modulation for fine-tuning system airflow and pressure.
Type D (Bearing Pedestal / Coupling Drive): Heavy-duty pillow block bearing housing with oil/grease lubrication, designed for elevated operating temperatures and high continuous loads.
Heavy-Duty Structural Skid & Base: Integrated carbon steel mounting base designed with pre-drilled anchor bolt holes and compatible with rubber or spring vibration isolators.
Airflow Capacity Range: 1,990 to 226,500 m³/h (1,170 to 133,300 CFM).
Total Pressure Output: 180 to 3,350 Pa (0.72 to 13.45 in. w.g.).
Operating Gas Temperature: Standard ambient up to 80℃; High-temperature structural upgrades available up to 250℃.
Installation Style: Rigid floor-mounted or elevated structural steel frame mounting.
To ensure zero damage during international ocean freight, all export fans undergo strict export preparation:
Factory Acceptance Testing (FAT): Every unit is subjected to a 30-minute no-load operational test, vibration spectrum analysis, and insulation resistance testing prior to dispatch. Factory Test Certificates are supplied with shipping documentation.
Export Packing: Rotors and machined shaft surfaces are coated with anti-rust oil. Small-to-medium fans are packed in IPPC ISPM-15 compliant fumigation-free wooden crates, while large volute casings are disassembled for optimized container loading (LCL/FCL).
