I.Application

The specific speed of SJG oblique flow ducted fan ranges between centrifugal fan and axial flow fan。It is not only with a high pressure coefficient of centrifugal fan & high flow coefficient of axial flow fan, but also the characteristics of effective wide district.

Besides the aerodynamic characteristics of SJG oblique flow ducted fan, its structure greatly simplifies the design and the installation. The inlet air direction and the outlet direction are in the same axis, the same diameter of duct flange and the duct, which make it easy to install. Centrifugal fan requests 90degree of the transition duct, but not necessary for it. With little occupation, it does not affect the piping layout and direction. It is most suitable pressurization for the pipeline and ventilation, especially demonstrate the superiority of its compactness in small room or space.

It is widely used in civil ventilation and chemical industry, replacing low-pressure centrifugal fan for saving space, simplifying design and facilitating installation. The oblique duct fan are the best choice in the situation that can not be satisfied by axial fan.

SJG oblique duct fan can carry raw air and corrosive air. If we change into explosion-proof motor, it can carry explosive and flammable air with the temperature below 80degree. 

II.Structure characteristics

Oblique duct fan have unique straight line with the aerodynamic parameters in between axial fan and centrifugal fan. Its basic structure and air circulation are shown below.
