About this video

Keruite Air Conditioning Group presents our 4-72 series industrial centrifugal fans, one of the most widely used and trusted ventilation solutions in the market. Known for their high efficiency, low noise, and reliable performance, these fans are the preferred choice for general ventilation in factories, large commercial buildings, and industrial facilities worldwide . The 4-72 series features a single-suction, backward-curved centrifugal impeller with airfoil blades, delivering superior aerodynamic performance with minimal energy loss . The impeller consists of 10 backward-inclined airfoil blades with curved front and rear discs, precision-balanced both dynamically and statically to ensure smooth, vibration-free operation . Available impeller diameters range from 280 mm to 2,800 mm . **Key Specifications:** | Parameter | Range | |-----------|-------| | Airflow Capacity | 1,000 – 300,000 m³/h | | Static Pressure | Up to 3,000 Pa | | Operating Temperature | -20°C to +80°C (standard); up to 200°C with cooling wheel option | | Speed Range | 250 – 2,900 RPM | | Fan Diameters | No. 2.8# to 20# | **Available Drive Configurations:** - **Type A:** Direct drive, motor directly coupled to impeller (for No. 2.8-6) - **Type B:** Belt drive with bearing support (for larger models No. 16-20) - **Type C:** Belt drive with motor external to airflow - **Type D:** Coupling drive with bearing support **Key Product Features:** - **High Efficiency:** Advanced impeller design with optimized blade angles achieves high total pressure efficiency - **Low Noise Operation:** Airfoil blade profile and precision balancing minimize turbulence and vibration, resulting in quiet performance - **Durable Construction:** Heavy-duty steel casing and impeller with anti-corrosion coating; stainless steel and aluminum alloy options available for specialized applications - **Flexible Airflow Direction:** Casings available in left or right rotation with multiple outlet positions - **Low Maintenance:** Backward-curved impeller resists dust accumulation; optional cleaning doors for easy maintenance access - **Custom Configurations:** Special designs available including high-temperature (up to 500°C), wear-resistant, corrosion-resistant, and explosion-proof variants **Typical Applications:** - Factory and workshop ventilation - Large commercial building air circulation - Power plant ventilation systems - Dust collection and exhaust systems - Air handling equipment integration - Drying and heat recovery systems - Boiler air supply and induced draft - Tunnel and mine ventilation **Quality Assurance:** Each 4-72 series fan undergoes rigorous testing before shipment, including airflow performance validation, dynamic balancing, vibration analysis, and electrical safety inspection. Our products are manufactured in compliance with ISO9001 standards and carry international certifications. Have a ventilation project requiring 4-72 centrifugal fans?
