Cooling principle suction fan suction fan: the suction fan is the use of air convection cooling principle of negative pressure ventilation, Xinzhou suction fan curtain, the installation location of the door or window --- naturally draws fresh air, indoor outdoor hot gas quickly forced out, Baoding suction fan curtain, any problems can improve poor ventilation, ventilation cooling effect of up to 90% -97%. A suction fan specific field of application, suction fan for high temperature or smell of workshop: such as heat treatment plant, casting plant, plastics plant, aluminum factories, shoe factories, leather factory, electroplating plants, a variety of chemical plants. 2, especially for the need to cool down and need some place humidity. Such as cotton, woolen mills, jute mill, weaving plants, chemical plants, Jingbian, bomb factory, knitting, silk factory, hosiery and other textile mills. 3, for warehousing and logistics.

Wind FRP square suction fan is minimal. The opening of the suction fan glass steel square frame righting floor, while wind and small wind while the situation is more obvious than galvanized square suction fan, the opportunity to place the wind rotates clockwise.
