Model: HIF-II (double speed) series fire exhaust fan, high temperature motors, totally enclosed motor built with high special motor cooling system efficiency, low noise, reasonable structure, small size, easy installation application: high-rise building , drying room, underground garage ventilation or high-temperature exhaust. Continuous operation at 300 degrees for 60 minutes or more high temperature, medium temperature conditions of continuous operation at 100 degrees 20 hours / times without damage, fire is the ideal necessary equipment. Francis HTF temperature exhaust fan is a series of products, performance of new fans between axial and centrifugal fans between the inlet collector fitted with silencer, fitted with deflector outlet, exhaust fan manufacturers, and designed as a secondary intake, help to reduce the ambient temperature of the motor. Temperature exhaust mixed flow fan with high efficiency, energy saving, low noise, compact, light weight, small size, reliable operation, easy installation, can run at 300 ℃ environment one hour, because the underground chambers by underground and space factors limiting, Hami exhaust fan in the wind and air pressure and other factors of satisfaction coefficient, fire fighting systems and smoke exhaust ventilation is usually used in combination can, therefore, we use two-speed fan in the underground garage, the same It is basically the same fans and the same duct. Under normal circumstances, as the exhaust ventilation fan running at low speed applications, when a fire, stand both become fast running fan, exhaust fan maintenance, as fire exhaust fan applications. So a machine 2 with not only decrease the cost of health made, save space, exhaust fan buy, more important thing is to greatly enhance the configuration of the application rate and credibility. Should the smoke exhaust and harm are basically two systems left, but the fire exhaust fan only, produce fire bet when running, usually fewer applications, as revealed problems not easily be discovered in time and get the repairs, and real fire When not easy to guarantee Hang Shun betting applications. The two-speed fan just to overcome this deficiency, usually as an exhaust fan running, the problem appears to be excavated and get timely repairs, often in a good posture drops ready.
