How Do Pulse-Jet Filters Work?

Pulse-Jet Dust Filters contain filter media assembled in cages or cartridges that are closed at the bottom and open at the top. The media is installed in the filter housing so that the open top of the media is connected to a plate or tubesheet. The contaminated air is conveyed to the filter housing where it flows through the filter media, exiting through the tops of the bags or cartridges through the tubesheet. This clean air is then exhausted from the filter housing. Dust accumulates on the outside of the bags or cartridges. Eventually excess dust will hinder airflow through the media and must be removed. This is done by a short burst of high-pressure air injected into the inside of the media, causing the media to expand and release the dust on the surface. The pulse is blown through a venturi nozzle at the top of the media, causing a shock wave to travel the length of the media to the bottom. The shock wave flexes the filter media, causing the dust cake to be released.
