Fire exhaust fan and an overview of the scope of application HTF series fire temperature exhaust fan for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Continuous operation at 280 degrees Celsius for 30 minutes or more, the medium temperature of 100 degrees Celsius continuous operation 20 hours / times without damage, fire is the ideal necessary facilities. Fire exhaust fan selection and performance model 1, fan performance properties listed in the table is the most efficient performance within range, according to the air volume is divided into five performance operating points, whichever is the selection according to the performance table. Qualified fan factory is rated flow, total pressure error does not exceed ± 5%, the performance of the selection list is performance under standard conditions, regardless of the state performance standards are technical documents or ordering request shall prevail. 2, the wind turbine installation can be divided into horizontal and roof type, air volume, total pressure, dimensions and other properties have special requirements. 3, HTF-Ⅰ, HTF-Ⅱ represents 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 dedicated 4, HTF-X as a silencer fire temperature exhaust fan, the user can choose according to the actual needs of different species. 5, HTF-W series rooftop fire temperature exhaust fan, the user can choose according to actual needs retardant fiberglass hood or steel hood. 6, HTF-D as a low pressure type fire temperature exhaust fan. 7. Special Note: GYF and HTF series fan is a similar product.
