Dust collection systems consist of four major items. All of them are important and can cause a dust collection system to underperform. The major items are the exhaust fan, dust collector, ductwork, and hoods/pickup points. While the exhaust fan provides the motive power to collect the dusty air, its performance is affected by each of the components. This means that if one of the other components isn’t operating as designed, the whole system will be affected. Ductwork is usually by far the largest component and often the most overlooked. Depending on the size of your system, the ductwork can span hundreds of feet and have dozens of side streams. The ductwork is like railroad tracks, it moves the dusty air from one place to another.
