Exhaust fan Features: 1, HTF series fire temperature exhaust fan system state-level "Spark" product of the project, with excellent performance exhaust fan fire, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation Features. 2, HTF Fire fan high temperature performance: Fan tested in accordance with GBJ45-82 Fire Code standards, establish higher standards of corporate internal control to ensure that the system can run continuously at 300 ℃ high temperature for 60 minutes or more, under 100 ℃ temperature conditions Continuous 20 hours / times without damage, widely used in high-level civil, oven, underground garages, tunnels and other occasions. 3, performance HTF Fire 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 fan factory qualified under fire exhaust fan rated air flow, total pressure value error does not exceed ± 5%, the performance of the selection table is a performance standard state, regardless of the technical documentation or ordering requirements. Fan installation maintenance (1) before installation must scrutinize whether the fan: damage deformation, the connecting portion loose impeller and duct exhaust fan fire collision problem spot, found the above problems must be repaired before installation. (2) the installation should pay attention to the direction of rotation of the impeller and the airflow direction signs, do not allow the fan reverse (reverse) run. (3) the fan base and the ground surface must be natural combination fire exhaust fan model is complete, do not allow the base to force the join beat. (4) Ceiling fans need a positive level (fan base at the bottom), the load-bearing surface must be flat bottom fan; (5) The fan connected to a three-phase voltage 380V, 50Hz power supply. (6) is connected with the fan inlet and outlet pipes should not be borne by the fan duct, should additional support. (7) After the installation is complete, be sure to check the internal fan and piping, there should be no debris or tools fall or left. Fans need to test run 10 to 30 minutes, to be confirmed after the fan is operating normally before being officially used.
