1.Is the diagonal fan belonging to axial fan or centrifugal fan?

Oblique flow fan, from the professional point of view, it belongs to axial flow fan, because the axial flow fan outlet and inlet angle is 180 degrees, and the centrifugal fan is 90 degrees.

2.axial fan and the fan duct diameter?

In general, the wind pipe diameter mainly accords to the length of the pipeline, and the fan air volume and pressure, which decide the diameter size. Therefore, in this issue, obviously, the answer is the axial flow fan to determine wind pipe diameter. Moreover, the pipe diameter must be chosen properly, because the wind pipe diameter is too large or too small, which will both affect the normal running of axial fan.

3.if the pressure is 980Pa, can the axial fan reach the pressure? In addition, if the current is too small, will it burn down the fan?

The axial fan is not suitable if the pressure request is 980Pa. because the upper limit of pressure for this fan is 300Pa. so If you want to reach the requested pressure, centrifugal fan is the proper choice. And the small current will not burn down the fan, unless there's locked rotor of fan.
