Roof ventilators come in various specifications and styles, with a wide range of applications. They can be tailored to meet different requirements for usage scenarios, air volume, pressure, and noise.

Roof Exhaust FanThe following three types of fans: A,Axial Flow Roof FanModel DWT-I is suitable for medium and low-pressure, high-flow applications. It can also be designed as a reversible fan for air supply and exhaust, featuring equivalent performance in both forward and reverse conditions, such as the DWT-Ⅴ model; B, Centrifugal Roof Fan: Models DWT-Ⅱ and DWT-Ⅲ are available, suitable for situations with lower air volume and higher pressure requirements; C, Motorless Turbine Exhaust Fan: Model DWT-Ⅳ is an ideal energy-saving ventilation device that uses the pressure difference between indoor and outdoor air to drive special arc-shaped blades rotating around the axis to exhaust indoor air.
