Supply fire exhaust fan low noise fan HTF-type exhaust fan? Specializing in the production of various specifications HTF series fire temperature exhaust fan, HTFC series of fire centrifugal wind chassis, 4-724-79 series centrifugal fan, SWF series mixed flow fan, DWT series roof fan, YDF range abduction air, DXG Series rectangular duct fans, SWF series mixed flow fan GXF series of oblique flow pipeline fan, T35 series axial fan, HLF Series Francis wind chassis, GLZ series pipeline centrifugal axial fan, SDF series Pipeline pressure axial fans is your preferred brand a, HTF series of high temperature exhaust fan fire Overview:.? ◆ HTF series fire temperature exhaust fan with excellent performance, high temperature performance, high efficiency, covering than the centrifugal fan small, convenient installation. ◆ HTF series fire temperature exhaust fan of "national fixed fire extinguishing systems and fire-resistant component quality inspection center" test qualified, the performance of the leading domestic level. ◆ High temperature performance: Fan Test conform GBJ45-82 Fire Code standards, established above the standards of corporate internal control assurance system to run more than 60 minutes continuously under high temperature 300 ℃ conditions, for 20 hours at a temperature of 100 ℃ / second not damaged, it is widely used in the senior civil oven, underground garage, tunnels and other occasions. ◆ for a wide range: according to different requirements of senior civil use of variable speed or multi-speed drive form, in order to achieve one machine (ie, when used through ventilation and fire high-temperature exhaust) purposes; for the axial-flow airfoil (HTF-Ⅰ, Ⅱ) and mixed flow (HTF-Ⅲ, Ⅳ), so fans of the series has a wide range of performance parameters. If users require a higher noise, it can be made into a silencer-type fan. ◆ High efficiency: This series of fans using advanced CAD software designed and developed by the multi-objective optimization and development of new products, the test shows that the fan efficiency greater than 80%, part of the large fan number is greater than 85% and has a flat efficiency curve characteristics conducive to energy conservation . ◆ easy installation, covering less than the centrifugal fan: The fan base in the form of axial fans and mixed flow fan, direct pipe connection or wall mounting with the wind, the installation forms can be vertical or horizontal to a large extent. saving footprint. ? Two, HTF series fire temperature exhaust fan performance option and model? Description: 1, the fan performance table lists the properties in the most efficient range, according to the air volume is divided into five performance points, the selection according to the performance table prevail. Qualified fan factory at rated air flow, total pressure error does not exceed ± 5%, the performance of the selection table 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, such as when to air flow, total pressure, dimensions and other properties have special requirements, I will plant you separate design and production. 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 type fire temperature exhaust fan, leaf type with oblique flow: There HTF-Ⅲ (single speed), HTF-Ⅳ (double speed) two. 4, HTF-Ⅹ 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 or steel hood hairdryer. ?
