A dust collection system is an air quality improvement system used in industrial production shops to improve breathable air quality and safety by removing particulate matter from the air and environment. This system will be used for collection of dust while operation eighter from multiple points (or) Single source. . 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..

Larger systems utilize a two-stage system, which separates larger particles from fine dust using a pre-collection device, such as a cyclone or baffled canister, before drawing the air through the impeller. Air from these units can then be exhausted outdoors or filtered and recalculated back into the work space.

 Air filtration units are designed to process large volumes of air to remove fine particles (2 to 10 micrometres) suspended in the air. In industry, round or rectangular ducts are used to prevent build up of dust in processing equipment.
