Suction fan 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 poor ventilation problems can be improved machine, FRP 1380 suction fan, ventilation cooling effect of up to 90% -97%. Features Machine using SMC materials design, with low investment costs, air volume, low noise, low energy consumption, stable operation, long life, high efficiency, shutters automatically shuts dust, water, beautiful; to Hair is a modern workshop the best choice for cooling ventilation, but also ventilation. Environmental protection, energy saving ventilation and cooling suction fan will become the mainstream equipment market. Introduction of Application A, suitable for high temperature or smell of the shop with fan: as heat treatment plant, casting plant, plastics plant, aluminum factories, shoe factories, leather factory, electroplating plants, a variety of chemical plants. B, applied to labor-intensive business: such as garment factories, various assembly plant, cafes. C, ventilation and cooling greenhouse horticulture, livestock farms cool. D, especially for applications that require cooling and requires a certain humidity locations. Such as cotton, woolen mills, jute mill, weaving plants, chemical plants, Jingbian, bomb factory, knitting, silk factory, hosiery and other textile mills. E, cooling principle applies to the field of warehouse logistics suction fan: suction fan 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 hot outdoor gas quickly forced out, any problems can improve poor ventilation, metal plant ventilation and cooling, ventilation cooling effect of up to 90% -97%. Powerful suction fan advantages: 1, less investment, low energy consumption. The same cooling rate, the one-time investment of about air conditioning sixth, tenth about the air conditioning running costs; 2, significant cooling effect, the temperature can drop to about 28 degrees, in line with the body temperature, if fit Well water tank as the source better effect, the effect can be compared to air-conditioning; 3, fresh air, moist air up to 99% cleanliness; Features 1, air flow design, ventilation capacity 47000m3 / h. 2, low energy consumption, low operating costs, only 1 kWh of electricity per hour. 3, using a special motor, direct-type structure (to change the traditional belt drive) to improve efficiency and simplify the structure and reduce maintenance costs. 4, SMC molded fiberglass blades, easy to install, attractive and durable without deformation. 5, frame made of composite material SMC (sheet molding compound) by a molding temperature, light, insulation, no rust, no aging, moisture, acid, durable, long life; and flexible product design, Easy-scale production, and has the advantage of safe and beautiful, and increase service life. (Continuous use 10--20 years) 6, the air downstream principle shutters, no power, no need to switch, can effectively waterproof, dustproof, suction fan parameters, and nice. 7, planning the installation does not occupy space, without air duct, suction fan parameters, can be installed in any place, how many square curtain. 8, wide application, almost all places need ventilation and cooling can be used, especially for high temperature or smell of industrial production plant cooling, such as textile mills, shoe factories, electronics factories, furniture factories, chemical plants, food plants, machinery plants, electroplating plants, etc., can also be used to cool job or full cooling.
