Exhaust fan Features: 1, HTF series fire temperature exhaust fan state-level "Spark" product of the project, with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation and so on. 2, HTF Fire fan high temperature performance: Fan tested to meet fire code standards GBJ45-82 exhaust fan total pressure, higher than the standard set up internal control systems to ensure exhaust fan noise, and can run continuously under high temperature 300 ℃ condition more than 60 minutes at a temperature of 100 ℃ for 20 hours / time is not damaged, widely used in high buildings, oven, underground garage, tunnels and other occasions. 3, performance HTF Fire fan performance table lists the properties in the most efficient range, according to the air volume is divided into five performance points, according to prevail in the selection of the performance table. Fire fans quality products manufactured in the rated flow exhaust fan flow, total pressure error does not exceed ± 5%, the performance of the selection list is performance under standard conditions, regardless of the technical documentation or the ordering request. 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. Applications exhaust fan, exhaust fan, liter by liter Rui Rui Electrical and Mechanical Ventilation and Air Conditioning Electrical Equipment Factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) strong, credible, Shandong Texas fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Swiss mechanical and electrical liter into the brilliant and you work for a better future!
