What is a Centrifugal Fan & How Does it Work?

Centrifugal fans (centrifugal blowers) are a common type of fan used in consumer and industrial products to move air or other gases. A centrifugal fan consists of three main components: a motor, a fan blade, and an enclosure.

Our application engineers design all of these components to accommodate an application. Some common design criteria are the size of the motor, the shape of the fan blade, the direction of rotation, and the materials of construction.

How a Centrifugal Fan Works

The rotating fan blade creates a low-pressure area at the center of the blade and a high-pressure area at the edges of the blade. It also adds kinetic energy to the air. The low-pressure area at the center of the fan creates a vacuum that draws air into the fan. The air flows from the center of the fan to the outside edges of the fan. Ultimately, it flows out of the enclosure around the impeller in the desired direction. The design of the overall system accounts for the 90-degree turn in the flow path.

Centrifugal fans come in a variety of designs. Several components, including the type of fan blade used, the design of the enclosure (housing), and the materials of construction, determine the complete fan design.

Industrial Applications

Industrial centrifugal fans and blowers accommodate a variety of applications. For example, chemical processing, corrosive gas handling, dust collection, dryers, fume control, process cooling, and process heating. Below are some of the most common, with links to more information and related fan designs.

5 Common Centrifugal Fan Applications:

Clean Air Handling

Material Handling

Centrifugal force material handling fans can process particles such as sand, plastic pellets, sawdust, wood chips, grain, paper trim, pet food, and countless others. They range from small and light to larger, heavier and more abrasive. AirPro has been innovating based on customer input and building industrial material handling fans for years with increasing efficiency and durability. Learn More

Saturated Air Fans

Centrifugal exhaust fans frequently process saturated air, meaning there is moisture from humidity or various gasses in the air. These applications often require heavier duty materials like stainless steel and moisture-resistant coatings like epoxy. When we engineer custom fans, we start with an appropriate fan type and tweak the materials, finishes and other specifications. Learn More

High Temperature

Many industrial processes rely on high-temperature process heat. Operations like heat treating, stress relieving, industrial furnaces and ovens use convection to circulate heated air within the chamber. These process airstreams require specially designed centrifugal fans. Fans not properly designed for this purpose will catastrophically fail when used at temperatures above their design. Learn More

Customizing a Fan

Industrial fans need to meet a specific set of design criteria. We recommend working with an AirPro fan selection expert to design the best fan for your application. You will be working with industry-leading fan engineers to create customizable solutions to match your project requirements and budgets.

Centrifugal Fans vs. Axial Fans

Industrial environments commonly use centrifugal fans and axial fans, but they have very different performance characteristics.

Axial Fans

Axial fans serve applications requiring a large flow rate with a minimal drop in pressure. Axial fans pass air straight through the blades instead of creating a 90-degree turn in the direction of flow. If there is not a large pressure drop in the application, the axial fan can be preferable due to form, fit, & function.

In industrial contexts, we often see axial fans in equipment to exchange heat through environmental air such as Air-Cooled Condensers, Cooling Towers and Air Cooled Heat Exchangers. Examples include:

• Field erected cooling towers often utilized in industrial processes and in power generation facilities.
• Package cooling towers which are mainly used in HVAC applications.
• Air-cooled condensers which are a critical component in power plants and typically utilize large diameter fans.
• Air-cooled heat exchangers (ACHE), primarily for process industries (petrochemical, oil refining, and gas compression).
• Forced ventilation systems.

Centrifugal Fans

Centrifugal fans typically work in areas of little to no natural ventilation and are attached to a duct system, making them ideal for larger spaces.

When deciding which style of fan to use, you may want to consult an expert. AirPro application engineers will be able to examine your performance and installation requirements to assist you in determining which type of fan is most ideal for your specific application.

Standards

For the sizing of fans, the programming logic is developed according to engineering concepts homologated by international standards and institutions, such as:

• AMCA - Air Movement and Control Association International, Inc.
• ANSI - American National Standards Institute
• ASHRAE - American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.
• EUROVENT - Europe's Industry Association
• ISO - International Organization for Standardization

Sizing of the Fan

The correlation functions used to calculate dimensional and physical parameters of each new fan have their origin in the classical theories of fluid mechanics, becoming known as the Fan Laws or Affinity Laws, while the noise predictions are based on acoustic principles and guidelines established by professional organizations.

For better accuracy, the software can also perform calculations and analysis improved by considering Reynolds number, Mach number, compressibility, viscosity and specific heat of the fluid.

Calculations and Analysis

In a highly organized, flexible and friendly environment, the user establishes the design requirements and the software performs all calculations and analysis necessary for sizing of the fan:

1. The user provides the design parameters.
   • Fluid Type
   • Fluid Temperature
   • Fluid Density
   • Altitude / Elevation
2. The software adjusts the parameters in accordance with the fluid properties.
3. The software simulates the use of each type and size of fan.
4. The software calculates diameter and width of the fan impeller.
5. The software calculates the operating rotational speed.
6. The software analyzes the performance and suggests the most suitable fans.
7. The software generates a selection list with sorting and filtering capabilities.
8. The software plots performance curves of the selected fan, such as the following:
   • Flow Rate × Static Pressure
   • Flow Rate × Total Pressure
   • Flow Rate × Power - Brake Horsepower
   • Flow Rate × Static Efficiency
   • Flow Rate × Total Efficiency
   • Flow Rate × Sound Pressure Level - Noise
   • Flow Rate × Sound Power Level - Noise

Sound Spectrum

In addition to the aerodynamic requirements, the user can also set the fan installation conditions.

Installation factors significantly influence the sound spectrum of the ventilation system and consequently the level of noise sensed in the environment.

1. The user provides information about environmental characteristics and physical components of the ventilation system.
   • Noise Directivity
   • Inlet and Outlet Ducts
   • Acoustic Attenuators
   • Acoustic or Thermal Insulation
   • Noise Measurement Distance
2. The software adjusts the acoustic parameters of the fan in accordance with the operating point.
3. The software calculates the acoustic influence of each component of the ventilation system.
4. The software generates a noise calculation report for the operating point.
   • Fan sound spectrum in octave bands
   • Electric motor sound spectrum
   • Set sound spectrum: fan + electric motor
5. Lastly, the software calculates the noise for the full operating range of the fan and plots its curves.
   • Flow Rate × Sound Pressure Level - Noise
   • Flow Rate × Sound Power Level - Noise

Real Fluid

Usually, industrial fans are tested using ambient air; and their performance curves are published by manufacturers, conventionally referring to the standard parameters of this fluid at sea level.

In practice, however, most fans use air under adverse conditions, or even another type of fluid, and especially at altitudes other than sea level:

• Hot Air
• Cold Air
• Saturated Air
• Air containing Dust
• Air containing Solvents
• Vapors
• Fumes

• Exhaust Gases
• Corrosive Gases
• Flammable Gases
• Explosive Gases
• Toxic Gases
• etc.

Obviously, the physical properties of these fluids are different:

• Temperature
• Relative Humidity
• Density
• Composition
• Molecular Weight

• Compressibility Coefficient
• Viscosity
• Specific Heat
• etc.

Our software calculates the influence of these variants, adjusts parameters of the fans, and corrects their characteristic curves.

Thus, charts are displayed in a fully correct way, under the actual conditions of the user's application.

Compressibility

In ventilation systems, compressibility is the property of the moving fluid that reduces its volume as a function of the pressure increase resulting from the action of the fan.

Compressibility increases the density of the fluid.

The compression process generates heat which raises the outlet temperature of the fluid and consequently changes its viscosity.

All these variables modify the behavior and efficiency of the fan.

Our industrial fan software has advanced features that calculate and evaluate the influence of compressibility on fan sizing.

Viscosity

Viscosity is the physical property that characterizes the resistance of a fluid to flow.

It represents the internal friction of a moving fluid.

Unlike liquids, the viscosity of gases increases with increasing temperature.

The viscosity of the gases also increases with increasing pressure, but much less significantly.

The increase in viscosity implies an increase in the energy required to make the fluid flow and consequently changes the performance of the fan.

Our industrial fan software has advanced features that calculate and evaluate the influence of viscosity on fan sizing.

Fan Reynolds Number

In fluid mechanics applied to ventilation systems, the Reynolds number can be defined as the ratio of the inertial forces to the viscous forces within the fluid moved by the fan.

The Reynolds number makes it possible to predict whether a flow will occur in laminar or turbulent form.

If the viscous forces are dominant, the flow tends to be laminar.

If the inertial forces are dominant, the flow tends to be turbulent.

Laminar flow is characterized by smooth and constant motion of the fluid.

Turbulent flow is characterized by agitated and chaotic motion of the fluid, with eddies, vortices, backflows and other instabilities.

Therefore, the flow type changes the performance of the fan and consequently its energy consumption and efficiency.

Our industrial fan software has advanced features that calculate and evaluate the influence of Reynolds number on fan sizing.

FEG - Fan Efficiency Grade

Our industrial fan software is also prepared to meet the latest American requirements for fan efficiency classification.

The FEG classification system can be used by government agencies or regulatory bodies around the world to define the energy efficiency requirements of fans used in specific applications.

The FEG is a simple way to indicate the aerodynamic quality of the fan.

While the fan efficiency is a function of the operating point on the performance curve, the FEG is based only on the fan's peak total efficiency.

Similarly, our software also meets efficiency requirements of the European countries that prefer the FMEG classification system - Fan Motor Efficiency Grade.

Normative References:

• ANSI / AMCA 205 - Energy Efficiency Classification for Fans
• ISO 12759 - Efficiency Classification for Fans

Multiple Variable Graphs

In ventilation systems with variable demand, the use of adjustable speed drives is usually the best way to ensure maximum efficiency and minimum energy consumption.

Under such circumstances, it is essential that the designer has a broad view of the behavior of the fan to be selected.

Our software has the most advanced engineering charts with high resolution details, which show characteristic curves throughout the operating speed range of the fans.
