Cooling Fan Features: 1. Frame: high quality galvanized board, high strength, corrosion resistance and strong; 2. blades: six beautiful and durable stainless steel blades, by balancing test Changchun cooling fans, air volume, low noise, no distortion, no fracture; 3. Pulley: high strength aluminum-magnesium alloy casting heat, light weight, high strength; 4. Bearing: France imported bearings, high strength, low noise, long service life. Cooling fan housing a high compressive strength, before and after the shell is made of high quality ABS material, guarantee a material (some manufacturers use of secondary plastics, which then recycle old plastic, plastic color, poor, low intensity cooling fan, volatility) ABS material is relatively Other PP plastic Changzhou cooling fan, color is more bright, strong, not easily deformed two sides using the sheet metal structure, high strength, resistance to external pressure Weifang chicken cooling fan, not easily deformed body (ordinary mobile machine is fully plastic parts without compression, easily deformed) 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!
