Most Popular Air Handling Equipment-Centrifugal Fan

1
Centrifugal Fan
Centrifugal fans are varied from axial fans. They
create a high-pressure stream of air. It is
optimal for fans to decrease energy costs.
Centrifugal fans move air radially and improve
the air systems productivity.

Overview of Centrifugal Fan

• A centrifugal fan is often called a squirrel-cage
  fan or Industrial blower specifically designed to
  move air or other gases.
• Due to their simple design, Centrifugal fans are
  the most popular air-handling fans and can easily
  be manufactured than other types of fans.
• It is also called a blower, blower fan, or
  biscuit blower.

What is the difference between a blower and a fan?

• Generally, fans have blades for functioning or
  rotation that move huge amounts of gas with a low
  increase in pressure, which comes in a pressure
  ratio of up to 1.11. Whereas a blower has
  impellers for rotation, pressure ratio between
  1.11 and 1.2.
• Fans are electrical devices while blowers are
  mechanical devices. However, fans and blowers are
  used for cooling and air circulation in
  industrial machines, electronic equipment as well
  as HVAC systems.
• Unlike Fans, centrifugal blowers and positive
  displacement blowers are used in many industries.

How does a Centrifugal fan work?

• Centrifugal fans have a pump or motor that moves
  air. Centrifugal fans take the surface air and
  move it rapidly. It pulls the air inside the
  blower and then the propeller pushes it back.
• The two main components are the motor and the
  impeller.
• Centrifugal fans or blowers increase the pressure
  of an incoming air stream through a series of
  blades mounted known as impellers on a circular
  hub, speed up air and change the direction of the
  outer flowing air, usually by 90.
• Centrifugal fans or industrial blowers are ideal
  for high-pressure applications.

Understanding the Characteristics of Centrifugal
Fan

• Provides a higher energy efficiency, constant
  airflows.
• Multiple airflows and pressure combinations.
• Due to self-cleaning characteristics, it is easy
  to maintain. Enhanced durability.
• Multiple sizes are available to accommodate
  diverse applications.
• It helps to reduce operational costs and
  problems.
• The design of the centrifugal fans provides the
  ability to accommodate the additional load.
• The industrial blower can process all types of
  air such as wet, dry, and clean air.

7
Types of Centrifugal Fan

• Five different types of centrifugal fans are used
  in air handling based on the type and shape of
  the fan blades.
• Forward Curved Fans
• Airfoil Blade Fans
• Radial Blade Fans
• Backward Inclined Fans
• Inline Centrifugal Fans

What are centrifugal fans or Industrial blowers
used for?

• Centrifugal fans are more popular in todays
  modernized air handling applications.
• Widely used in moving air or gas and are ideal
  for sustaining larger air systems.
• Centrifugal fans are commonly used in factories
  or warehouses to move objects along a conveyor
  belt.
• In residential applications to operate air
  through a duct in your home.
• In-car cleaning and washing, once the wash is
  complete, large fans or Centrifugal fans dry your
  car off in only seconds.
• In an air-con system, furnace, or hood duct.
• Airflow in vehicles and HVAC systems.
• Centrifugal fans, highly used in several process
  industries and air pollution systems.

Choosing centrifugal fan vs axial fan, all
depends on the application that you need it to
do. How much air it needs to move and where it
needs to work, easily helps you to figure out
which type of centrifugal fan is the most
appropriate choice for you?
