Fire smoke exhaust fan is mainly used for industrial and civil construction and civil air defense projects, usually also be used for indoor ventilation. Motor with high temperature and a cooling air circulation system, long-term operation at 100 ℃ medium gas can be smoothly transported 280 ℃ smoke up to 40 minutes or more. Horizontal, vertical, cabinet, three types are available. When dual exhaust ventilation, optional two-speed motor, low speed ventilation, high speed exhaust. Francis fan using advanced three-dimensional flow model design, but also has a large flow axial fans and centrifugal fans high-pressure characteristics, small size, high efficiency, easy installation, saving space for a variety of situations in the pipeline pressure ventilation. Oblique flow fan glass steel and steel are two, both centrifugal fans and axial fans high pressure coefficient flow coefficient characteristics of high efficient wide area, low energy efficiency, noise, can be directly connected in series in the pipeline ventilation, easy installation, saving space, no fan room paiyanfengjpaiyanfeng Model Description: 1, the performance of fan performance table lists the properties in the most efficient range, according to the performance of the air volume is divided into five working points, according to prevail in the selection of the performance table. Fan factory is qualified products at rated air flow. 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, our company will provide you with a 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 fire temperature exhaust 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 like .S) overview, with the same machine number than the centrifugal fan large amount of wind, air pressure higher axial fans, and other characteristics can be axially mounted; low noise, low power consumption, efficient wide area, easy to install and use than the centrifugal fan, reliable operation. Features 1. Compact structure, easy installation, reliable operation; The fan than axial or centrifugal small size in the case of the same amount of wind, air pressure can be directly connected to the duct, horizontal or vertical installation, easy operation features. 2. Low noise: The fan casing is specially designed to greatly reduce the outflow of noise. In the unit amount of wind, air pressure unit operating conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed, can obtain higher fan pressure. In the industrial and mining enterprises and senior civil ventilation system can replace the low-pressure centrifugal fan or replaced without the need for a large number of high-pressure axial fan silencer measures. 3. Wide range of applications: This series points single-speed and two-speed two models, according to different occasions, changing the mounting angle of the fan, change the number of leaves and converting speed to its requirements. Strong technical force, advanced exhaust fan fire Wuhu, production equipment, detection means perfect, Ma'anshan exhaust fan fire, have their own fans, HVAC accessories professional production workshop and damper, smoke damper actuators professional production lines, Huangshan fire exhaust fan, and have professional equipment 120 (sets), professional and technical staff of 36 people, the annual output value of over ten million yuan. The company for 10 years Bei industry and commerce administration departments as 'contract and keeping promises units', 'a member of fire protection products', 'AAA credit enterprises' and so on, and passed the ISO9001: 2000 quality system certification. Company products are: fire damper, smoke damper actuators, temperature sensors, high-temperature exhaust axial fan, Francis fan, ramps flow fan, tunnel fans, induced fan, a variety of national standard centrifugal fan, axial fans , HVAC central air conditioners, fan coil air conditioners, air-conditioned terminal aluminum outlet, valves, large factories, power plants and high-strength aluminum alloy rare manual, electric rain blinds and other products sold throughout the country, enjoy a high reputation. Wherein the actuator, damper, smoke fire damper, high-temperature exhaust axial fans has adopted a national fixed fire extinguishing systems and fire-resistant component of Quality Supervision and Inspection Center, and online access to test results the company has always been implementing the 'quality first, the user oriented, customer-centric, we continue to improve, 'the purpose, Hefei exhaust fan fire, pay close attention to internal management, improve product quality. Company chairman and managing Fangchun Tang sincerely welcome friends and experts to visit and seek common development.
