Francis (oblique flow) fan, high pressure coefficient than the axial fan, centrifugal fan flow coefficient than large exhaust fan quoted by the pressure and flow are "sort" of the occasion. It fills the gap between axial fans and centrifugal fans of. Along with easy installation features. Francis turbine combines axial and centrifugal fans feature shape looks more like a traditional axial fan. Cabinet can have open inlet, but more often the case, it has the shape of a right angle bend htfc exhaust wind chassis, the motor can be placed outside of the pipe. Excretion shell slow expansion to slow down the flow of air or gas, and the kinetic energy is converted to useful static pressure. There are fan impeller, housing, import collector, deflector, electric motors and other components. Impeller meridian acceleration characteristics of twisted flat welded on wheels. After balancing check roof exhaust fan, exhaust fan speed test, with good aerodynamic performance. Circular enclosure with silencer function is coupled into a whole set of wind. Outlet provided with baffle, having good air distribution, pressure stability. Second, the use of fans HL3-2A [SWF (B)] Series Francis fans are widely used in high-temperature exhaust ventilation and fire tunnels, underground garage, senior civil construction, metallurgy, factories and other places, HL3-2A [SWF (B)] series fan conveying gas temperature must not exceed 80 ℃, special circumstances can be used riot Francis fan. htfc exhaust wind chassis, exhaust fan, air-conditioning equipment provided by Hao Yang Hao Yang Air Conditioning Equipment Co., Texas. Air Conditioning Equipment Co., Texas Hao Yang (www.dzapjt.com) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Hao Yang air conditioning and you hand into the brilliant, for a better future!
