The 4-62 Centrifugal Fan, a versatile Centrifugal Blower, is designed for general ventilation in a variety of settings, including factories and large buildings. This Centrifugal Fan is adept at handling the input or output of air and other non-flammable, non-harmful, and non-corrosive gases, making it a safe and reliable choice for indoor environments.

Suitable for environments with medium temperatures not exceeding 80°C and containing minimal dust and hard particles (not more than 150 mg/m³), the 4-62 Centrifugal Fan is an excellent choice for maintaining clean air circulation. With 13 different machine numbers ranging from No.4 to No.16, this Centrifugal Blower can be tailored to meet specific airflow needs.

One of the standout features of the 4-62 Centrifugal Fan is its rotation angle flexibility. Available in both right-handed and left-handed versions, the fan's impeller can rotate in the direction that best suits your system's requirements. For models No. 4 to 6, the air outlet position can be adjusted from 0° to 225° in 45° increments, providing a high degree of customization. Models No. 7 to 12 offer three fixed air outlet positions at 0°, 90°, and 180°, ensuring a perfect fit for various system layouts.

Structurally, the 4-62 Centrifugal Fan boasts a robust design that includes a high-efficiency impeller with 12 backward-inclined blades, a volute casing made from durable steel plates, and an integrated air inlet that facilitates smooth gas flow with minimal loss. The transmission group, consisting of a main shaft, bearing box, and rolling bearing, is built for longevity and consistent performance.

①Impeller: It is composed of 12 backward-inclined thin plate-type blades.
② Casing: Ordinary steel plates are welded into a volute casing.
③ Air inlet. It is made into an integral part and installed on the side of the fan. The cross section parallel to the axial direction is a curved shape, which allows the gas to enter the impeller smoothly with less loss.
④ Transmission part. It is composed of main shaft, bearing box and rolling bearing.
