I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for ventilation equipment. Disadvantages suction fan suction fan, is the use of a large amount of exhaust ventilation to create negative pressure axial fans for short. Suction fan appearance is generally square, curtain price, mostly for galvanized sheet shell material. There FRP suction fan horn. Due to negative fan cooling effect, low investment costs, Yingtan curtain, running low power consumption and many other advantages, making it the best choice for the majority of factories, cafes, farms, greenhouses and other places of ventilation and cooling. Suction fan on the market today, many brands, many manufacturers to reduce costs, raw materials and other aspects of cutting corners, resulting in the appearance of seemingly identical fan, there is a huge difference in quality. And some cottage factory, only a few people put together a simple assembly, the quality of the products can not be guaranteed. Consumers how to choose? First, look at the fan Appearance: Good fan products, with high-quality housing are generally 1.0mm galvanized plate, appearance plump, heavy weight. Views are generally used 0.6mm sheet. Second, look at the motor: good products, motor generally use aluminum. Or full amount of steel, the appearance of good anti-rust treatment. Views are generally poor motor housing, or even replace copper with aluminum to make the motor coil. Third, look at the details: Good company's products, general technical updates will be based on market demand.

I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for ventilation equipment. Natural health plant cooling suction fan + cooling wet curtain is a set of ventilation, cooling, ventilation, filter dust, increase the oxygen content in a fresh air a new generation of energy saving ventilation and cooling equipment, cooling up to 4 ℃ -10 ℃. When the negative pressure ventilation fan normal operation, indoor produce negative pressure, forcing the outdoor unsaturated wet curtain air flows through the porous surface of the paper, the air in a large number of sensible heat into latent heat of vaporization, curtain cooling, forcing incoming air dry bulb temperature dropped to close to the outdoor air wet bulb temperature. Wet screens humidification cooling system is running, the steady flow of the outdoor air after cooling pad introduced into the chamber to cool. When the suction fan is running, the outside surface is completely wet gas through the wet curtain paper, mixed with dust in the air, impurities in the wet curtain paper paste; at the same time, since the fan drive when the indoor air ventilation from the same direction of the discharge, the dust generated by machinery production workshop, the flying cotton fibers with respect discharged wind plant, does not stay in the workshop and the machine table, so that the workshop 24 hours can be kept clean and refreshing . Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, chiller suppliers. Supply: Nanchang suction fan, FRP suction fan Nanchang, Nanchang curtain, wet curtain Nanchang, Nanchang household air coolers, air coolers Nanchang, Jiangxi suction fan, Jiangxi household air coolers, air cooler Jiangxi, Nanchang and other 金祥云 in Nanchang plant cooling ventilation equipment industry enjoyed a high reputation, has many years of industry experience, can provide customers with products and professional services. I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for ventilation. Ventilation air flow method in accordance with different power, and natural ventilation can be divided into two major categories of mechanical ventilation. First, the pressure of natural ventilation Natural ventilation is pressing rely on indoor and outdoor air temperature caused by the prize or outdoor wind loads on the building formed, indoor and outdoor air exchange, curtain installation, thereby improving indoor air surroundings. Due to natural ventilation of the need dedicated power plant, a large amount of affection for the workshop is an economical and effective ventilation methods. The downside is that naturally into outdoor air can not be processed in advance, as the exhaust air from the room, if the dust contains harmful or toxic gases can not be decontaminated. In severe cases, it can contaminate the surrounding environment had an adverse effect, plant workshop harmful substances into the human body. In addition, the natural ventilation of ventilation in general is affected by outdoor weather conditions, unstable ventilation. Second, the mechanical ventilation by means of a method of the power leaving the air flow generated by the suction fan, called mechanical ventilation. Since the air flow and pressure of the suction fan can be selected as desired, so this method of ventilation to ensure ventilation, and to control the air flow direction and air velocity, air can also press the required parameters, the intake and exhaust processing . Obviously, mechanical ventilation system complexity than natural ventilation, a large investment and operation and management costs. Curtain price, Nanchang wet curtain fan mounting calls (certified), provided by the Nanchang Jin Xiangyun Yingtan curtain cooling ventilation plant.
