A structure known as local fan axial fan, axial fan air flow is the same direction (ie, wind direction and parallel to the axis), such as electric fans, air conditioning unit fan is an axial flow fan run, is commonly used mining industry a fan, which is different from the general fan. Conventional axial fan motor and fan blade in a cylinder, the shape is a cylinder, for local ventilation, easy installation, ventilation effect is obvious, safe, hair dryer can be connected to the designated lookout area. The square axial fans, the biggest difference is that the conventional axial fan, square axial fan motor and fan blade in a cylinder, the shape is square and convenient than the cylindrical wind turbine installation. 2 is the use of air convection cooling principle of negative pressure ventilation, the installation location of the door or window --- Natural inhale fresh air, indoor outdoor hot gas quickly forced out, any problem can improve poor ventilation, cooling ventilation effect up to 90% -97%. First, the square Axial fans Features:? Machine using CAD / CAM design, with low investment costs, air volume, low noise, low energy consumption, stable operation, long life, high efficiency, shutters automatically shuts achieve the anti- dust, water, beautiful; to hair, modern plant cooling ventilation is the best choice, but also ventilation. Environmental protection, energy-saving square axial fans, cooling wet inexpensive equipment market will become the mainstream of ventilation and cooling. Second, the square axial fans Applications: 1, for the exhaust ventilation: installed outside the shop window, usually selected downwind, out of ventilation, the smell gas extraction; more general chemical applications. 2, with the wet curtain use: as a workshop to cool scorching summer, no matter how hot your workshop, wet curtain - suction fan systems can make your workshop temperature dropped to about 30C, and a certain degree of humidity. 3, square axial fans used: high temperature or smell of the workshop: such as heat treatment plant, casting plant, plastics plant, aluminum factories, shoe factories, leather factory, electroplating plants, a variety of chemical plants. It applies to labor-intensive enterprises: as garment factories, all kinds of assembly plant, cafes. Horticulture greenhouse ventilation and cooling, cooling livestock farms. Particularly useful for cooling 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. For warehousing logistics.
