Ventilation Ball

By using of colored steel and 201 or 304 stainless steel, ventilation ball or roof ventilation is mounted on the edges of the roof. It needs no electric supply to keep going. The building will be replenished with fresh air, greatly increasing air circulation and improving working conditions. The roof ventilation comes with many features of no need for oil and electricity, no need to maintain, and simple to install. It is able to work under the conditions of 3.2 kilometers per hour gentle breeze or more than 3 ℃ temperature difference between indoors and outdoors. This mechanism can offer users a comfortable and tranquil environment, ideally suitable for places which need to be adequately ventilated such as workshop, plant, warehouse and more.
