Blowers Industry Information
Blowers are
air blowers
or blower systems which provide air and gas movement in ventilation,
circulation and drying applications. Blowers and fans are used in
industrial, manufacturing, commercial and retail settings to ventilate,
circulate, cool and dry.
Industrial blowers
reduce heat levels in factory operations; moisture in bathrooms,
greenhouses, gyms and spas; smoke and odors in cooking and processing
applications, and gaseous fumes in chemical and oil manufacturing
facilities. Ventilating
exhaust fans replace stale or contaminated air in hot, dusty or smoky workplaces and restaurants with fresh, normal temperature air.
Industrial fans and air blowers refresh or lower air temperatures in cooling applications, while
high velocity fans assist in product drying applications.
Blower fans are industrial blowers that also use a metal fan for cooling and drying applications.
Centrifugal blowers
and regenerative blowers are impeller-based, high-efficiency blowers
commonly used in ventilation, cooling and drying applications as well
as pneumatic bulk conveying; centrifugal and regenerative blowers are
also used in reverse to provide vacuuming action in packaging
applications.
A wide spectrum of industries
use blowers for various ventilation, air purifying, conveying and
drying applications, including agricultural, photography, automotive,
food processing, packaging, pulp and paper, printing, welding and
textile manufacturing industries. Regenerative blowers are also used to
provide aeration for ponds, sewage and spa pools. Construction
materials for blowers include durable plastics, metals or a combination
of both. The size variance between industrial blowers for various
applications can be immense. Some units are mounted into the framework
of a system or piece of equipment, complete with vibration absorbent
brackets which house both the fan itself and its power supply. These
large, self-contained systems are only used in large manufacturing or
air circulation applications. Portable air blowers are much smaller and
are transportable from place to place for use in temporary circulation
or air transfer, such as at construction sites or when cleaning up
spills and water damage.
Fans and blowers
are made using one of two main designs: radial or axial. Air currents
are generated from circulating blades which direct flow based on their
aforementioned designs. Centrifugal blowers, unlike other blower types,
use impeller blades which take in air through the blower's center and
force it out at a perpendicular outlet; this process increases airflow
pressure and velocity. Blowers and fans are classified based on how
the fan is constructed; three classes were developed and are recognized
by the Air Movement and Control Association. In most cases, larger
class numbers correlate to greater 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 other
rating systems and standards.
Blowers are
essential in many manufacturing processes and facility air pollution
control systems, as well as many other drying and finishing processes.
Air blowers and fans provide healthier areas through the reduction of
odors, air pollution, contamination and smoke, and they may also
provide environmental benefits through a decrease in heat and humidity
levels. Industrial blowers are available in many configurations of
velocity, pressure, airflow direction and speed. When choosing a
blower, manufacturers and facility managers consider the environmental
conditions, pressure levels and surface areas of the application.
