HTF series fire temperature exhaust fan. It is optimized design and development of new products. It has a high efficiency, a flat curve characteristics conducive to energy conservation. The machine uses direct-drive motor exhaust fan, according to different requirements of senior civil construction, the use of single-speed or multi-speed drive in the form of exhaust fan models to achieve when ventilation temperature exhaust ventilation and firefighting purposes exhaust fan price, with a horizontal or vertical direction can be installed features. The products are widely applicable to senior civil, oven, underground tunnels and other occasions garage exhaust fan manufacturers, both as ventilation, can also be used as blowing smoke exhaust fan capacity should be required to increase airflow value of not less than 10% to 20% of the surplus amount. Exhaust fan for the selection of the main control parameters temperature, air flow, total pressure, efficiency, noise, electrical power, speed and shaft power. Exhaust fan at a temperature not higher than 85 ℃ conditions should be long-term normal operation. Exhaust fan shall ensure that: When the transmission medium temperature at 280 ℃ when continuous work 30min, and still continuously at medium temperature cooling to ambient temperature during normal operation. Exhaust fan applications, up Swiss mechanical and electrical (online consultation), exhaust fan, ventilation and air conditioning provided by the liter Swiss mechanical and electrical equipment factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
