Cooling fan series corrosion FRP fan [Features] 1. rational bell design, low noise cooling fan Changzhou, cool winds of Weifang chicken fan, ventilation and strong, low running costs 2. bearings, high strength, low noise, Durable [Application] are widely used in animal husbandry, greenhouses, industrial plants and other places ventilation and cooling, which can effectively rule out foul gas cooling fan, eliminating hot, smoke, exhaust Changchun cooling fan, dust and so on. Cooling fan cooling principle is: When the fan is running into the cavity negative pressure, so that the outside-air flow through the porous moist wet curtain surface forces the curtain air dry bulb temperature dropped to close to the machine outside air wet bulb temperature, ie Cooler outlet dry bulb temperature is lower than the outdoor dry bulb temperature 5-12 ℃ (dry heat areas up to 15 ℃), the more air is dry and hot, the temperature difference is bigger, the better the cooling effect. Weifang chicken cooling fan, cooling fan, Qingzhou Minhua Qingzhou temperature control equipment supplied by Chinese citizens thermostat plant. Temperature Control Equipment Factory Qingzhou public Hua (www.minhuawenkong.com) (www.minhuawenkong.com) (www.minhuawenkong.com123) strong, credible, Shandong Weifang fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead China and China Qingzhou temperature control equipment and you hand into the brilliant, for a better future!
