As we all know, a large amount of smoke and heat fire, and consume large amounts of oxygen. On its hazards, particularly at night to smoke, smoke contains many toxic elements, even though non-toxic, can also lead to hypoxia due to combustion asphyxiation death. Every fire accidents in the burned persons, most are also the first to be smoked fainted after being burned when the fire smoke spread fast temperature exhaust fan fire, levels of up to 0.5-0. 8m / s two-speed exhaust fan, vertical up to 6-8m / s. In the fire, the one fire, and then a smoke control. Is off the fire extinguishing, broken smoke source, smoke control system was to provide safe passage to escape, and to facilitate the initial fire; smoke control system is referred to as the smoke and smoke two parts. Today, while the height of high-rise buildings, but also the depth development of space, underground development, and high-rise buildings in the basement, the smoke control system is very important. The design of the unit concerned, we should pay attention to prevention in the design, exhaust design. HTF (A) fire temperature exhaust axial fans using advanced CAD-aided design systems, is the more optimized design developed new products with high efficiency characteristics curve flat, conducive to energy conservation. Optional molded axial flow impeller, built high temperature motor, arranged a special motor cooling system. Use two-speed motor direct-drive htf exhaust fan fire, to one machine (that usually send exhaust ventilation and fire when using high-temperature exhaust), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, high efficiency, small size, easy installation (horizontal, vertical, lifting can be), etc., are widely used in high-rise buildings, drying room, underground garage, subway, tunnels and other occasions to send fire smoke and exhaust ventilation . Press GA211-1999 Fire fan high temperature test methods, can run at 400 ℃ more than 100 minutes of continuous high temperature, medium temperature at 100 ℃ continuous operation 20 hours / time is not damaged, it has been approved for use by fire departments in major cities nationwide. Fans of the series may use the occasion of the installation requirements, peripherals silencer box, made HTF (A) -X box-shaped exhaust fan the fire. Detailed temperature of high-temperature exhaust fan fire HTF HTF fire exhaust fan is widely used in high buildings, drying room, underground garage, subway, tunnels and other occasions and sent fire smoke exhaust ventilation. Press GA211-1999 Fire fan exhaust fan high temperature test methods, can run at 400 ℃ more than 100 minutes of continuous high temperature, medium temperature at 100 ℃ continuous operation 20 hours / time is not damaged, has been the major city fire department authorized use. Fans of the series may use the occasion of the installation requirements, peripherals silencer box, made HTF (A) -X box-shaped exhaust fan the fire. Erdos exhaust fan, Chen Yu-conditioned, high-temperature exhaust fan fire by Wu Cheng Chen-yu air-conditioning Limited. Erdos exhaust fan, Chen Yu-conditioned, high-temperature exhaust fan fire is wucheng Chenyu Air Conditioning Equipment Co., Ltd. (www.wccykt.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, contact: sand manager.
