Shandong exhaust fan, exhaust fan fire the first sale of 2015 models, speed to rush to buy 1, exhaust fan, with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation and so on. 2, performance exhaust fan performance table is listed in the most efficient range of performance, 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, 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. 3, exhaust 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. As in recent years fire accidents continue to occur, but also improve the public's awareness of fire safety, especially some large high-rise building, due to its internal structure is complicated, very serious consequences in case of fire. So fire exhaust system must be designed, exhaust fans daily attention to maintenance, when a fire fan can function properly. When the level of fire protection system maintenance, in addition to the exhaust fan and the performance of individual components need periodic tests to detect other parts. Mechanical smoke, exhaust system, fan, outlet, exhaust port and other parts should be regular maintenance, such as to remove dust seven, add oil, etc., and always check the exhaust valve and other hand start units and prevent malfunction of protection devices It is intact. Every 1--2 weeks, or fan room by the fire center to start the fan load operation 5min. The whole floor outlet, exhaust valve once the mechanical action test annually. This test may be separately opened manually by the site, the fire control room remote control to open or binding assay fire alarm system linkage opened by the system. Exhaust valve and outlet of the test do not always linked fan, fan interaction after several fan supply should be cut off, only for valve port open test.
