1. The pipeline fan discharges the polluted air directly from the indoor to the outside without filtration. The indoor enviornment maybe temporarily improved, but the outdoor environment is polluted. It will be checked by the environmental monitoring department.
2.Pipeline exhaust fan will discharge the cooling( or heating) to the outdoors during the process of taking out the indoor fume and dust, the discharged amount can be at least a few hundred cubicmeters per hour and at most thousands of cubic meters, so that causing the full load operation if air conditioning equipment and wasting huge amount of electric power, but the professional fume purifier is circulated in the room.
3. Because of the long pipelinr of professional exhaust fan, its motor power is quiet large, generally about 5 kilowatts, however, the power condumption of professional fume purifiber is generally about 80-320 watts, so it is extremely saving in electric energy.
4. All of the pipeline exhaust fan is fixed installation ands can not be moved. If thee is any need in station adjustment, plant repair and removal, it almost all can not be used again.
5. The ventilation effect of pipeline exhaust system is good in the initial half year of installation, usually, its ventilation effect will be greatly reduced after six months due to dust accumulated on the inner wall and can not be cleaned, at last, it not only wastes the electricity, but also the fume can not be exhausted completely, which can cause severe damage to the staff's body. Usually, the poisoning incidents and occupation disease are caused by this condition: if the combustible dust s accumulated on the inner wall of pipeline, it probably causes fire an explosion, so it should be highlyemphasized.
6. Even if a welding station is working, the pipeline exhaust system has to be operated, but the fume filtering system is not like that, which works only in the welding station, so it is convenient and energy-saving!
The experimental data and application results show that the fume purifiber is light and compact, easy to install, flexible in movement and high in hedge ratio, which can solve the above various problems.
