About Industrial Blowers
Industrial blowers and air blowers are systems that
provide air and gas movement in ventilation and circulation applications.
They are used to stir up the air in cooling applications, and to replace
stale or contaminated air with fresh air in ventilation applications.
Fans and air blowers are used in numerous drying and cooling processes.
Industries that utilize industrial fans and air blowers include agricultural,
chemical, medical, oil/gas, automotive, food processing, mining and construction
industries. Blowers are used to reduce heat levels in factory operations;
moisture in bathrooms, greenhouses, gyms and spas; smoke and odors in
cooking and processing applications and to control gaseous fumes.
Fans and blowers are made using one of two main designs: radial or axial.
Air current is generated from circulating blades, which direct flow based
on their aforementioned designs. Construction materials for blowers can
be a range of durable plastics and metals and usually a combination of
both. The size variance of industrial blowers can be immense. Some units
are mounted into the framework of an environment, complete with vibration
absorbent brackets, which house both the fan itself and its power supply.
The size is also largely dependent on the size of the environment in
which the blower is to be used. Portable air blowers are also available
and used for temporary circulation or air transfer, such as at construction
sites or when cleaning up spills or water damage.
Many blowers and fans are classified with numerical designation that
is based on how the fan is constructed. These three classes were developed
and are recognized by the Air Movement and Control Association. In most
cases, the larger the class number correlates to the greater the performance
and cost of purchase. This classification is not required by the government
of all blowers, so other functional and reliable blowers may be classified
under another system of rating.
Industrial blowers provide numerous benefits. Air blowers and fans provide
healthier areas through the reduction of odors, air pollution, contamination
and smoke. Blowers provide environmental benefits through a decrease
in heat and humidity levels. Industrial blowers are available in many
configurations, which vary in airflow direction and speed. When choosing
an industrial blower, consider industrial application, environmental
conditions, pressure levels and surface areas. Consult an industrial
blower manufacturer for further information on individual systems.

Types of Industrial Blowers
- blow
or pump air through openings in a system. Applications include pools,
Jacuzzis, and spas, fish tanks
and aquaculture applications.
- are used for ventilation purposes. In axial flow
fans, air maintains parallel movement within the fan, and maintains
linear
movement during emergence from the fan.
- are more useful in air pollution control than axial
flow fans are. In centrifugal blowers, air maintains perpendicular movement
in relation to the fan shaft while in the fan system, and emerges rotationally
from the fan outlet.
- are specially designed
for use in corrosive environments or any application that involves
chemical or gas movement. Fiberglass
is often used in this type of construction.
- , release air after two cycles of circulation
within the blower. Crossflow blowers are
found in applications
involving large areas requiring low pressure and high levels
of airflow.
- are
used in applications that transfer large amounts of air for use in
compression situations such as in
the automobile industry.
- require an electric motor for operation. Electric
blowers cover a number of products, ranging from hair dryers
used in beauty salons to leaf and lawn blowers.
- are
ventilation systems used to reduce or eliminate odors, smoke, moisture
or stale air from an area by removing
the offensive
air and replacing it with fresh air. Exhaust
fans are common in kitchens, restaurants and bathrooms.
- are
used to control gas flow and gas pressure. Gas blowers process methane,
natural gas and other gases in gas
well and chemical applications.
- provide high levels of air movement.
- are made from different materials than residential or consumer fans and are used in industrial settings.
- are used in applications where oil free air
and almost silent operation are desired. These blowers
tend to be small
and use a small amount of energy to function.
- are used in greenhouse and lawn and garden applications,
involving movement of air over a large area or heavy-duty
air movement.
- are
used in the paper, photography and recreational industries for applications
including ink and film
drying and pool and spa aeration. During operation, air enters
the blower and moves
centrifugally out of the blower through the rotational
force of the blower blades; however, during this process
of rotation some
of the
air drops past the blade and moves through the
cycle again, which is why the blower is known as a regenerative blower.
- generically
refer to any type of blower that is built in a turbine style, consisting
of rotating
blades, which create the
air flow that is then blown.
-
are called such because they essentially derive their blowing power
via a vacuum which can either inhale or exhale a vast amount of air.
When vacuum blowers exhale, they technically are not vacuums.
