Centrifugal fans are one of the most important air circulation equipment and are among the most efficient fans on the market today.
It has quite a few details that you should know if you are looking for the right centrifugal fan.
This article will answer some of the basics for you to quickly solve your doubts:
What is a centrifugal fan
Centrifugal fans are sturdy, usually drum-shaped units used to provide high-pressure air flow for cooling, ventilation, and other purposes.
Centrifugal fans or centrifugal blowers are pumps or motors that move air and are known for their reliability, adaptability and low noise output.
The two main components of a centrifugal fan are the motor and the impeller.
In contrast to a propeller that pushes air, an impeller draws in or pulls air.
They can be used to move gases and air, and require little maintenance or cleaning, even in harsh industrial environments, with a fairly long service life.
How does a centrifugal fan work
Centrifugal fans are commonly used in residential applications to move air through the ducts in the home.
You may also see these in commercial settings like car washes. After washing, a large fan will dry your car in seconds. Those fans are centrifugal fans. They absorb outside air and move quickly, creating a pressure differential. As long as the pressure differential is maintained, the air will continue to flow and your car will dry out quickly.
The working principle of the centrifugal blower is relatively simple. In effect, the rotational energy is transferred into the air or gas. This means that the impeller has the mechanical function of a rotor—the rotating part that introduces energy into the system. The opposite of a rotor is a turbine, a device that removes energy from a mechanical system for use elsewhere.
Types of centrifugal fans
There are various choices of centrifugal fans, usually by the shape of the impeller of the centrifugal fan, or by the way they enter the air.
There are four basic types of centrifugal fans, each of which has a suitable application area.
Radial
High pressure fan with medium airflow.
Forward Curve
Medium pressure, high airflow fan.
Backward Curve
High-pressure, high-flow, high-efficiency fans.
Airfoil
Highest efficiency fan, best for clean air applications.
Application of centrifugal fan
Centrifugal fans are used in a wide range of scenarios, bringing a lot of help to production and life.
Centrifugal fans are used for:
-
Heating, ventilation and cooling (HVAC) or building ventilation systems
-
Dust removal fan
-
Air Conditioning System
-
Air Filtration and Pollution Control Devices
-
Industrial conveyor
-
Large-capacity dryers (for example, those used in commercial car washes)
-
Fluidized bed aerators (devices used to add oxygen to water or other fluids, i.e. sewage aeration)
-
Backwash (self-cleaning) filter
-
Gas boosters (for moving high pressure gas or increasing gas pressure)
-
Vehicle engine
-
Industrial furnace
What is the difference between a blower and a fan?
The primary difference between a blower and a fan is that a fan is electrically powered, whereas a blower is mechanical. Electric fans use propellers to push air, whereas blowers use impellers that propel air through a low or high pressure system.
The main points of choosing a centrifugal fan
Consider the following factors when choosing a centrifugal fan:
-
Pressure requirements
-
Required airflow
-
The temperature of the location where the fan will run - warmer locations may require a more powerful fan
-
Altitude of work site
-
The type of environment in which the fan operates. Is the incoming air clean, polluted, dry or moist?
