One challenge to designing a manufacturing process is choosing an effective
dust collection system that will fit the limited available plant space. Low
ceilings pose a challenge for high-efficiency cyclones due to their long
tapered bodies. In many cases the dust collector must be placed outdoors or
partially protruding through the roof. This can be an unfavorable arrangement.
If a traditional cyclone dust collector is installed horizontally, then it
loses efficiency due to particulate settling on the side of the collector and
being carried out with the exhaust gas.
In contrast, counter-cyclonic dust collectors, such as the Aerodyne
SplitStreamô Dust Collector, use a secondary air stream that directs material
toward the collection hopper, and may be installed horizontally with virtually
no loss of efficiency.
As the dirt-laden gas stream is drawn in to the collector, it passes
through a stationary spinner which imparts a rotational flow and forces
particulate toward the walls of the collector. A powerful secondary air stream
is injected into a manifold where it enters the separation chamber through a
series of nozzles. The secondary air stream intercepts the collected
particulate and carries it to the hopper. Because this design does not rely on
gravity to bring the dust to the hopper like conventional cyclones, its
operational efficiency is not affected by horizontal installation.
This type of dust collector may be suspended from a ceiling, conserving
valuable space on the manufacturing floor. It also saves money compared to
cutting a hole through the roof or building a site for the dust collector
outdoors. By the way, outdoor installation may encourage condensation that can
shorten service life and reduce efficiency. Finally, horizontal, high-efficiency cyclones may be maintained without the need for tall scaffolding that can
pose a safety hazard to workers.

horizontal cyclonic dust collection works.
