1、 Product Overview
The DWT-IV type motorless turbine exhaust fan breaks through traditional thinking patterns in design, with curved blades driven by airflow, indoor and outdoor temperature differences, and gentle winds to operate without the need for electricity. It is the latest revolution in the field of ventilation design. The guide vanes and blades operate synchronously, accelerating gas flow and increasing exhaust volume, reducing installation costs, and saving energy during operation. Reduce wire short circuits or power loads by not using electricity; When a fire occurs due to other factors, smoke can be quickly expelled to increase escape space and time.
DWT-IV type motorless turbine exhaust fan can extract indoor hot and exhaust gases, immediately reduce indoor temperature, form temperature difference pressure, and draw in equal amounts of cool and fresh outdoor air for circulation and ventilation.
2、 Product Features
1. DWT-IV type motorless turbine exhaust fan does not require electricity, can operate continuously, is efficient and energy-saving, and operates without noise.
2. The exhaust fan bearing adopts fully enclosed ball bearings and lightweight stainless steel blades, which have the characteristics of light weight and long service life.
3、 Product process
1. Blade: Made of stainless steel curved blades, stamped and formed by hydraulic pressure.
2. Chassis: Made of stainless steel and cut with a shearing machine, the middle hole is formed by hydraulic flanging.
