Industrial Blowers

About Industrial Blowers and Blowers Including: Air Blowers, Exhaust Fans, High Velocity Fans, Centrifugal Blowers & Industrial Fans.

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

• Air blowers blow or pump air through openings in a system. Applications include pools, Jacuzzis, and spas, fish tanks and aquaculture applications.
  
• Axial flow fans 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.
  
• Centrifugal blowers and fans 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.
  
• Corrosive duty fans 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.
  
• Crossflow blowers, or tangential blowers, 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.
  
• Displacement blowers are used in applications that transfer large amounts of air for use in compression situations such as in the automobile industry.
  
• Electric blowers 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.
  
• Exhaust fans 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.
  
• Gas blowers are used to control gas flow and gas pressure. Gas blowers process methane, natural gas and other gases in gas well and chemical applications.
  
• High velocity fans provide high levels of air movement.
  
• Industrial fans are made from different materials than residential or consumer fans and are used in industrial settings.
  
• Low pressure blowers 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.
  
• Power blowers are used in greenhouse and lawn and garden applications, involving movement of air over a large area or heavy-duty air movement.
  
• Regenerative blowers 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.
  
• Turbine blowers 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.
  
• Vacuum blowers 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.

Common Terms Related To Industrial Blowers

Air Changes - The amount of time, expressed in minutes, that is takes for industrial blower systems to replace air in an area.

Air Distribution - The delivery of outdoor or conditioned air via industrial blowers to various spaces in a building, usually by mechanical means.

Air Velocity - The rate and direction of air movement produced by industrial blowers.

CFM - Abbreviation for cubic feet per minute; a measurement of the amount of air industrial fans and industrial blowers move through ventilation and circulation during operation.

Circulation - The process used by industrial blowers and industrial fans for moving air around within a specific area.
 
Cross Ventilation - Air that enters on one side of a room and leaves on a different side of the same room as it is blown by industrial blowers or industrial fans.
 
Damper - The mechanism responsible for the regulation of airflow by industrial fans or industrial blowers systems; dampers consist of inlet dampers, which regulate airflow into industrial blowers or industrial fans systems, and outlet dampers, which control air movement out of industrial blowers or industrial fans systems.
 
Fan Blade - The fan component extending from the hub of industrial blowers or industrial fans that rotates, cutting into the air and producing air movement. Fan blades may stick straight out in a radial position, curve forward in the direction of fan wheel rotation or curve backward.
 
Fan Drive - The fan mechanism responsible for controlling the movement of the fan wheel on industrial blowers or industrial fans, including fan wheel speed.
 
Fan Wheel - Fan component consisting of a hub and blades, which rotate about the wheel in order to produce air movement of industrial fans or industrial blowers.
 
Hub - The point on an industrial fans wheels from which the fan blades extend.
 
Multizone - A building or part of a building that comprises a number of zones or cells.
 
Static Pressure - The amount of resistance in a circulation or ventilation system that industrial fans or industrial blowers must surmount to ensure proper air movement.
 
Total Pressure - The total amount of pressure, measured in Pascals, that industrial fans or industrial blowers produce, including both the static pressure and the velocity pressure.
 
Velocity - The rapidity of air movement in a ventilation system produced by industrial blowers or industrial fans, measured in feet per minute (fpm).
 
Velocity Pressure - The amount of pressure in a circulation or ventilation system resulting from air movement from industrial blowers or industrial fans.
 
Ventilation - A process of industrial fans and industrial blowers in which air is moved into, out of and between different areas. Ventilation is used to replace old, stale, odiferous or contaminated air with fresher, cleaner air.
