One, low noise roof fan (DWT Series) roof fan characteristics
The characteristics of low noise rooftop blower (DWT Series) are multiple grid types and wide application: according to the different pressure, air volume and noise requirements of the occasion, the following types of fans are selected.
A, axial flow roof fan: model DWT- I type, suitable for medium and low pressure, large flow of use. At the same time, according to the needs of the user, it can also be designed to be a two-way rotary reversible type, with the characteristics of the equivalent of positive and negative conditions.
B, centrifugal roof fan: type DWT- II, DWT- type III type two types, suitable for small air volume and high pressure requirements.

Two, low noise roof fan (DWT Series) roof fan use
The DWT series roof fan is divided into two types. One, axial flow roof fan: model DWT- I type, suitable for medium and low pressure, large flow of use. Secondly, the centrifugal roof fan: the type DWT- II, DWT- type III type, suitable for small air volume and high pressure requirements. No motor turbine exhaust fan: type DWT- IV type, suitable for commercial buildings and company mining enterprises (light steel structure roof) exhaust air ventilation.
