Dust collection systems work on the basic formula  of capture, convey and collect.

First, the dust must be captured. This is accomplished with devices such as capture hoods to catch dust at its source of origin. Many times, the machine producing the dust will have an port to which a duct can be directly attached.

Second, the dust must be conveyed. This is done via a ducting system, properly sized and manifold to maintain a consistent minimum air velocity required to keep the dust in suspension for conveyance to the collection device. A duct of the wrong size can lead to material settling in the duct system and clogging it.

Finally, the dust is collected. This is done via a variety of means, depending on the application and the dust being handled. It can be as simple as a basic pass-through filter, a cyclonic separator, or an impingement baffle
