Industrial Dust Collection Systems
Dust collection systems are used to remove
particulate from process gases as a form of pollution control. This process is
also useful for capturing valuable materials that may have other industrial
uses. The nature of mechanical separation allows cyclones to act as classifiers,
collecting the larger particles and sending the fines to a final filter. In this
way industrial dust collection systems can be used to sort waste from valuable
materials or contain explosive materials.
The Aerodyne SplitStream™ Dust Collector is a counter cyclonic dust collector with no major moving components. It is capable of handling a wide range of materials with minimal maintenance. The unique counter cyclonic design eliminates excessive wear and allows the collection of abrasive material. The cyclone can be installed vertically or horizontally.

The Aerodyne GPC Cyclone Dust Collector is an improvement over conventional cyclones. The unique design provides a compact unit that is available in horizontal or vertical configurations. The GPC Cyclone Dust Collector does not require a long, tapered body making it ideal for plants and workshops with limited floor space or overhead clearance.

How it Works
Our industrial dust collection system consists of fabric filter bags, a cyclonic dust collector, or combination of the two. In cyclone dust collection, air (or other gas) laden with particulate is made to spin (vortex) inside a conical chamber. Centrifugal force causes particulate to move to the walls of the chamber where it gains inertia. Then gravity pulls the particulate into a hopper for dust collection. This is called cyclonic separation. Sometimes multiple cyclone dust collectors are used with a common inlet and outlet.
Counter Cyclonic Dust Collection
Counter cyclonic dust collection is a cyclone dust collector with a secondary air stream that reduces wear on the cyclone walls and increases efficiency. Some other cyclones use a ground plate to reverse the vortex and increase efficiency that way.
A cyclone-based dust collection system requires little maintenance because it has no filters to replace and no moving parts except for the blower.
Filter media dust collectors such as cartridge filters and bag houses are usually able to capture fine, light particles easier than cyclones, however cyclones are often used upstream of filters as a pre-treatment, to remove the majority of dust and extend the service life of filters.
Cyclonic dust collectors have other advantages over filter media. Filters often do not allow collected particulates to be recovered for reuse. Also, installed before a bag house on high heat processes, a cyclone can act as a spark arrestor. Finally, unlike filters, cyclone dust
collection actually works more efficiently as humidity increases.
