Product Details

1、 Product Overview

1.1 DWT-IV type motorless turbine exhaust fan uses natural wind to drive the blades, generating centrifugal force to make the air flow,Due to its relatively thin and light leaves, even a faint breeze can make it rotate. When the turbine rotates, centrifugal force is generated, which releases the hot air below the turbineGas, smoke, and humid gases are sucked up and discharged. When air is drawn away from the turbine, a low-pressure zone, known as the chimney effect, is conveniently formed directly below the turbine. fromAs the turbine continues to rotate, fresh outdoor air also continuously flows in, thus achieving the effect of natural ventilation and cooling.

1.2.DWT-IV type motorless turbine exhaust fan does not require electricity, operates continuously, is highly efficient and energy-saving, and has no noise or sparks. The exhaust fan adoptsCircular arc-shaped blades, with gaps between each blade. When rotating, the blades complement each other to fill these gaps, and a large amount of rainwater flows along the circular nodesThe line is thrown out, and a small amount of rainwater flows along the leaves and blades onto the roof, without flowing into the turbine. At the same time, the rotating turbine allows air to flow out through the gaps between the blades,Block rainwater from entering and have weatherproof properties. The exhaust fan bearing adopts fully enclosed ball bearings and lightweight stainless steel blades, making the whole machine lightweightLong lifespan, generally with a service life of over 15 years.
