XGF series fire temperature exhaust fan performance models illustrate a selection and performance of fan performance table is listed in the most efficient range of performance, according to the performance of the air volume is divided into five operating point, the selection by performance Table prevail. 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 state performance standards are technical documents or ordering request shall prevail. 2, the fan installation can be divided into horizontal and roof type, such as when to air flow, total pressure, mounting dimensions and other properties have a specific request, I will provide you separate design and production. 3, XGGF-Ⅰ, XGF-Ⅱ, said pressure type fire temperature exhaust fan, leaf type with axial flow: (double speed) of two XGF-Ⅰ (single speed) and XGF-Ⅱ; XGF-Ⅲ, XGF -Ⅳ representation pressure fire temperature exhaust dedicated 4, XGF-BX for silencer type fire temperature exhaust fan, the user can choose different types on the basis of reality necessary. 5, XGF-W Series rooftop fire temperature exhaust fan, the user can choose flame-retardant fiberglass hood or steel hood necessary based on reality. 6, XGF-D for low pressure type fire temperature exhaust fan. Usefulness and personality: XGF (HTF) series fire temperature exhaust fan for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Can continue running more than 60 minutes at 300 ° C high temperature, 100 ° C under conditions of media continue to run 20 hours / times without damage, fire is the ideal necessary facilities usefulness and personality: XGF (HTF) series fire temperature exhaust fan for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation.
