2. Manufacturing industries and industrial facilities that deal with dust particles
generated from the manufacturing process have unique dust collection
requirements to keep the work and external environment clean and reduce
pollution.
An industrial factory is not only responsible for providing healthy working
environments to workers but also for keeping the surrounding environment from
polluting due to its manufacturing operations. To operate some types of factories, it
is necessary to install robust de-dedusting systems. Different industrial processes
produce different types and sizes of dust particles. Some pollutants remain on the
ground, while some keep floating in the air and circulate within any enclosed space.

3. What is a de-dusting system?
The de-dusting system is an arrangement in that uses industrial fans to push or pull
away the particle-contaminated air from a specific area through a filtration unit that
arrests the dust particles. The de-dusting system might be necessary for warehouses
that store powdered materials if particulate matters infiltrate the space during
handling. For example, a de-dusting system is necessary for a warehouse that stores
and handles cement packed in bags. Depending on the type of dust generated by
the industrial process, different types of fans are put in place to accomplish the dust-
collecting tasks.
Centrifugal fans are best for de-dusting systems as these can handle high volumes of
dust loads, hence very popular across industries. The fans together with the dust
collectors form a complete unit of de-dusting systems.

4. Types of Centrifugal fans suitable for de-dusting systems
De-dusting systems require either positive or negative air pressure to remove dust
particles. Accordingly, industries use industrial centrifugal fans that produce forced
drafts or induced drafts of air for de-dusting applications and dust collection. Since
these fans produce high-pressure air streams, industries find these highly suitable
for separating solid granular particles from the process.
The most effective fans are the ones that have backward-inclined and radial-tipped
impellers. Whether the particles are irregularly shaped and heavy or powdered dust,
there are many methods of handling the particles to facilitate dust collection.
The choice of centrifugal fans suitable for dust collection systems depends on several
factors, and the most important ones are the particle size and the air volume for
filtration. By varying the design of the blades or impellers, fans can help to achieve
various tasks of dust removal and filtration.

5. Why are centrifugal fans most suitable?
Since dust removal requires regulated high-pressure airflow, centrifugal fans are
most suitable. These fans are constant volume equipment that operates under
difficult conditions such as corrosive gases, high or low temperatures, acidic fumes,
etc. Centrifugal fans of different sizes and capacities are part of the dust removal and
dust collection systems of factories. Centrifugal fans help to operate pressure-type
systems and depression-type systems.
Centrifugal fans with radial blades are useful for wood industries for extracting dust
particles directly through the fan. In depression-type de-dusting systems, flat blade
or backward inclined centrifugal fans are most appropriate. The fan positioned
within the air-filtering system or atop the cyclone in the kiln helps to remove
airborne particles. Depending on the type of dust removal requirements industries
can use standard centrifugal fans or custom-built fans that serve some specific
purpose.
