Product Details

Products Description

4-72 Centrifugal Fans can be used for indoor ventilation in general factories and large buildings, conveying air and other non flammable, harmless to human health, and non corrosive biological gases to steel. The B4-72 Fans can be used for ventilation of flammable and volatile gases. There should be no viscous substances inside the gas, and the content of dust and hard particles should not exceed 150MG/M3. The gas temperature shall not exceed 80 ℃. In order to facilitate user installation and use, we has designed a 2.8A-6A Fans, which adopts an integral bracket structure, and the Fans and motor are connected as one.

★ Our factory can design and manufacture 4-72 series Fans with vibration reduction platform for users. ★ Our factory can design and manufacture 4-72 double suction Fanss for users. ★ Our factory can design and manufacture high-temperature 4-72 series Fanss for users (maximum temperature ≤ 500 ℃). ★ Our factory can design and manufacture corrosion-resistant 4-72 series Fanss for users.

Large caliber air outlet with stable performance

Square air outlet, convenient for equipment docking, customizable inlet and outlet diameter, suitable for various occasions

Balance level, high and low noise, low frequency

Each impeller undergoes dynamic balance testing to maintain the desired balance level, fundamentally ensuring the long-term quiet and stable operation of the fan.

Optimize design for smoothness and efficiency

The fan adopts a rear curved centrifugal impeller optimized by CFD flow field simulation design. This design is more in line with aerodynamic characteristics, with high efficiency and more stable airflow. Simultaneously adopting FEA assisted design has improved the reliability of the structure.
