SJG Series Marine Diagonal Flow Fan

About product

A SJG series diagonal flow fan is a type of marine axial fan that combines features of both axial flow fans and centrifugal fans. It is designed to provide a balance between high airflow and increased pressure capabilities. Compared to axial flow fans, diagonal flow fans tend to have higher pressure capabilities due to the radial airflow component. However, they typically have lower pressure capabilities compared to centrifugal fans. The design of diagonal flow fans allows for a more compact size compared to centrifugal fans, making them suitable for installations with limited space.

Product Detail

The construction of a diagonal flow fan includes a cylindrical housing with an impeller positioned inside. The impeller consists of a series of blades or vanes that are curved in shape. These curved blades allow the marine axial fan to generate both axial and radial airflow components.

When the diagonal flow fan is in operation, air enters the marine fan through the axial inlet and is driven forward by the rotation of the impeller. The curved blades impart a tangential velocity to the air, resulting in an additional radial component of airflow.

SJG Series Marine Diagonal Flow Fan Structure

The marine fan features a unique diagonal flow structure, which allows it to effectively handle situations where axial flow fans cannot meet the requirements of duct ventilation. This makes it an ideal choice in such scenarios.

The SJG inclined flow pipe fan is suitable for transporting non-corrosive air and gas. However, it should not be used for gases containing viscous substances or with a high concentration of dust and rigid particles exceeding 150 kg/m³. By replacing the motor with an explosion-proof variant and utilizing aluminum impellers, plastic wheels, or FRP wheels, it can also handle flammable and explosive gases.

It is important to note that the temperature of the gas being conveyed should not exceed 80℃ to ensure optimal performance and longevity of the marine fan.
