Are you curious about how the filter bag on the dust collector works? see the explanation below!

     The filter bag itself is an air purifier part of the dust collector system. When the air carrying dust enters the dust collector system through the inlet channel, the baffle plate inside the inlet serves to prevent air from re-entering by guiding the airflow downward in the same direction. The air pipe in the baghouse will direct the heavier dust particles into the hopper (bottom dust collector). The remaining lighter dust particles will be drawn to the outer surface of the filter bag to be passed on to the next process. Dirty and dusty air passes through the bag filter leaving clean air which then passes through the air outlet.

    When dust accumulates in the filter bag, the dust cleaning system will work periodically (periodically) to maintain continuous operation. Periodic cleaning of the filter bag is done by injecting high pressure air (jetpulse) from the compressor with a short duration through a specially made inflatable pipe using a nozzle mounted on the top of each filter bag. High pressure air is sprayed alternately, this allows the other bag filters to continue working to continue the dust filtering process without stopping.


    pulse jet baghouse or pulse jet dust collector is the most common form of particulate air pollution control equipment. In addition to the jet pulse cleaning system, there are several other types of dust collector systems. Other systems commonly used are mechanical shakers and reverse air.
