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 Test conform GBJ45-82 Fire Code standards, establish higher standards of corporate internal control to ensure that the system can run continuously under high temperature 300 ℃ for 60 minutes or more, at a temperature of 100 ℃ Continuous 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 performance exhaust fan in the most efficient range, according to the air volume is divided into five performance point exhaust fan efficiency, according to prevail in the selection of the performance table. Fire fans quality products manufactured in the rated 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. The basic form of fire exhaust fan is an axial flow exhaust fan application structure, using high temperature motor, arranged special motor cooling system, products by the National Fire Equipment Quality Supervision and Inspection Center GA211-1999 "high-temperature exhaust fan fire test method "high-temperature test at medium temperature conditions of high temperature 300 ℃ continuous operation more than 60 minutes at a temperature of 100 ℃ continuous operation 20 hours / time is not damaged, can be used for dual exhaust ventilation.
