Industrial Air Filters: The Different Types
Jason Uvios
An air filter by definition is equipment or a machine which is so
designed that it can trap and hence remove from air solid particles
like mold, dust, bacteria and pollen from air. In any industry clean
air is directly related to production quality. And there are strict
standards that are needed to be maintained. Directly involved with the
manufacturing process, they can mean a lot of money of the company
rides on how they are functioning.
The various kinds of air purifiers in the industry are:
- Bag filters
- High Efficiency Particulate Air (HEPA) / Ultra Low Particulate Air
(ULPA) filter
- Fan filters
- Box filters
- Panel filters
- Pre filters
Bag Filters
These are generally used for removing dust in industrial filter
applications. The general flow is from outside to the inside of the
filter. It also depends on the kind of application. The separation of
the particles takes place on the external surface of the filter.
However, generally with other filters the partition takes place on the
inner surface of the bag filter.
High Efficiency Particulate Air Filters
High Efficiency Particulate Air Filters or more popularly known as just
the HEPA filters are widely regarded as the best of all filters. If
someone uses it in conjunction with activated carbon or zeolite
canister, it becomes a complete filter being effective not only against
particulates but also against odors and most gases. The history behind
HEPA filters is that it was developed by the Atomic Energy Commission
to allow their researchers work in a safe environment and provide them
protection from radioactive dust particles. The High Efficiency
Particulate Air filters are effective against particulates as small as
0.3 microns and they have an amazing efficiency rate of 99.97%. So what
it basically means is that if there are 10000 particulates in air, only
3 particles would be not trapped by the purifier. The HEPA filters are
mainly used for laminar airflow cabinets.
Fan Filters
These are made from fiberglass or some mesh-type substance. They are
meant to remove lint and other large particles. Such filters are
specifically used for industrial purposes.
As there are a lot many types of purifiers and space is limited, we
here can discuss only a few. But there are plenty of literatures
available on these filters in the Internet. If you are interested you
can always do further reading on this. This was meant only to be an
introduction.
