Exhaust fan exhaust fan price, with a special compartment temperature measures built circulating impeller can forcibly cool the motor, ensure that the motor temperature does not exceed a predetermined value. Run at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Can play a role of ventilation and fire smoke. The product was identified as Shandong Provincial Fire Department fire products sentinel production. Exhaust fan high temperature performance, high efficiency, small size, easy installation, etc., it can be used as temperature, humidity, corrosion-resistant type roof fans, used in electric power, petroleum, chemical, metallurgy and other high-temperature, high humidity industrial applications roof exhaust, ventilation. Exhaust fan Features: 1, HTF series fire temperature exhaust fan state-level "Spark" product of the project, with excellent performance exhaust fan principle, high temperature performance, high efficiency, covering less than the centrifugal fan, easy to install Features. 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 / times without damaging the exhaust fan specifications, 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 point exhaust fan, 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.
