 [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product --HTF exhaust fan fire] 1, the performance of the fan performance table is listed in the most efficient range of performance, according to the air volume is divided into five performance operating point, according to prevail in the selection of the performance table. Factory fan qualified under rated air flow, total pressure value error does not exceed ± 5%, the performance of the selection table is a performance standard state, regardless of the technical documentation or performance are subject to the requirements of the standard state orders; 2, the fan installation can be divided into horizontal and roof boiler fan, air volume, total pressure, mounting dimensions and other properties have special requirements; 3, HTF-Ⅰ, HTF-Ⅱ, said pressure type fire temperature exhaust fan, leaf type axial flow type: HTF-Ⅰ (single speed) and HTF-Ⅱ (double speed) of two; HTF-Ⅲ, HTF-Ⅳ representation pressure fire temperature exhaust professionals; 4, HTF-X to fire temperature exhaust silencer Smoke dedicated fan, the user can choose according to the actual needs of different types; 5, HTF-W Series rooftop fire temperature exhaust fan heaters, the user can choose according to the actual needs of flame-retardant fiberglass hood or steel hood; 6, HTF -D for low pressure type fire temperature exhaust fan; 7. Special Note: GYF and HTF series fan is similar products. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan] 1892 France developed into a cross-flow fan; in 1898, the Irish people to design a centrifugal fan blades 西罗柯 ago, and for all countries widely used; 19th century wind turbine technology, axial fan has been applied to mine ventilation and metallurgical industry blast, but the pressure is only 100 to 300 Pa, efficiency is only 15 to 25 percent until the later 1940s was get rapid development. In 1935, the German first axial flow fan for boilers and other pressure ventilation and the wind; in 1948, Denmark made the running variable pitch axial flow fan; rotating axial flow fan, axial fan meridional acceleration, oblique flow fan and cross-flow fans have also gained development. In the direction of gas flow, can be divided into centrifugal fan, axial, mixed flow and cross-flow and other types.
