HTF series of high-temperature fire exhaust fan Overview: HTF series fire temperature exhaust fan with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, convenient installation. HTF series fire temperature exhaust fan of "national fixed fire extinguishing systems and fire-resistant component quality inspection center" test qualified, the performance of the leading domestic level. High temperature performance: Fan tested in accordance with GBJ45-82 Fire Code standards, establish higher standards of corporate internal controls to ensure that the system can run more than 60 minutes continuously at 300 ℃ high temperature conditions, under 100 ℃ temperature conditions for 20 hours / times without damage, widely used in high-level civil oven, underground garages, tunnels and other occasions. 1. centrifugal fan wind chassis, the required motor power refers to conditions to be determined, together with the proper mechanical losses in terms of reserves, not the required full power outlet, such as the fan outlet is not connect pipes or adding external resistance and empty running, the motor burned in danger, just to be safe kitchen exhaust duct fans, should the fan outlet or inlet piping plus valve exhaust fan, turn off the fan when you start, After running slowly open the valve, is reached specified conditions exhaust fan price, and pay attention to fan current exceeds a predetermined value. 2. Fan allow full voltage start or step-down start, but it should be noted that the current full voltage starting 5 to 7 times the rated current, voltage starting torque and voltage proportional to the square two-speed exhaust fan fire, when the grid insufficient capacity, should start a buck. (When the power is greater than 11KW, should buck starter).
