Features editor HTF series fire temperature exhaust fan system national "Spark" product of the project, with excellent performance exhaust fan, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation. 2, HTF Fire fan high temperature performance: Fan Test conform GBJ45-82 Fire Code standards, established above the standards of corporate internal control assurance system exhaust fan wholesale production can run continuously under high temperature 300 ℃ for 60 minutes or more row Smoke fan manufacturers, 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. Factory fire fans quality products is 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 installation of orders for maintenance: kitchen fan is a kitchen indispensable key exhaust fan equipment procurement, advise against installation in the ceiling, to be installed in the engine room and so on, roofing or exterior wall for easy maintenance of the place. Working kitchen fan due to prolonged high temperatures, humidity, smoke gases. Regular maintenance is indispensable work. Failure: 1, the impeller blade leads to oily curvature, angle deformation, air volume total pressure parameters decreased significantly, reaching less than exhaust requirements. 2, the impeller oil stains causes the impeller to lose balance, increase shock, damage to the bearings. 3, harsh environments parts easily rust, damaged fan.
