K series fan of mine from DK40, DK45, K40, K45 and other mining wind turbines, K40, K45 series auxiliary fan drive using the most simple structure of the motor and impeller directly connected by the collector, the host body and diffuser and other components. Using new efficient airfoil blades twisted FD-7.1 Bureau Ventilator, installation angle adjustable, laying steady flow loop device so aerodynamic performance curve without hump, can be equipped with axial movement of the wheels on the base. So FD-6 # Bureau fan rotating machine manufacturers, with high efficiency and low noise, high efficiency district wide, stable performance, simple structure, easy to install, easy to use and so on. DK40, DK45 Series main fan using the same model, with the power of the two sets of K40, K45-type fan butted together, two counter-rotating impeller mutually FD-5.6 # rotating Council Ventilator price, constitutes spin structure. They drive type with the long axis of the main fan, compared with a high efficiency, low resistance Operations Bureau, saving construction investment, etc., with significant energy savings. FB series flameproof pressure-Axial local fan (hereinafter referred to as fan), a safe, reliable performance, low maintenance cost, long life, advanced airfoil blade design, low-low noise, high efficiency, energy consumption long-distance gas transmission capacity, stable operating performance and other characteristics. Aerodynamic performance fan meet mine tunneling face partial quantitative ventilation requirements, after connecting duct and pipe network system with a small loss, air long distance run in a small flow of regional stability, high efficiency region wide range of applications. Fan is mainly used for explosive gas atmospheres of gas and other coal mine local fan for push-use. FD-5 # rotating Council Ventilator, Ventilator Bureau, Zibo Blower Factory Co., Ltd. provided by Zibo Blower. Zibo Blower Factory Co., Ltd. (www.zibo-fengji.com) strong, credible, Shandong Zibo fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Zibo Blower and you hand into the brilliant, for a better future!
