Centrifugal Fans

Centrifugal fans, commonly referred to as blowers, are crucial for efficiently moving air or gas across various applications. These fans feature a unique drum-like structure that houses multiple fan blades, known as impellers. As the impellers rotate, they generate airflow by blowing air or gas from one location to another, serving purposes such as aspiration, cooling, ventilation, and material conveying.

Centrifugal fans can be categorized into single-stage and multi-stage blowers. Single-stage blowers are ideal for applications requiring uniform airflow, while multi-stage blowers are designed for scenarios that demand varying airflow at a fixed pressure. Choosing the right centrifugal fan ensures optimal performance and efficiency in your air movement needs.

At RS Australia, we provide a wide range of centrifugal fans to meet diverse industrial and commercial needs, such as for cooling, dust extraction, or other processes. Our extensive selection includes both single-stage and multi-stage centrifugal blowers, each designed to offer reliable performance in various conditions.

Types of Centrifugal Fans

RS Australia offers a comprehensive selection of centrifugal blowers, including forward curved, backward curved, and radial blade fans, each designed to ensure optimal performance across different applications.

Forward Curved Fans

Designed for high airflow and low-pressure applications, forward curved centrifugal fans are perfect for HVAC systems, ventilation, and electronics cooling. Their smooth airflow and energy-efficient design make them ideal for environments prioritising noise reduction.

Backward Curved Fans

Built for high-pressure applications, backward curved centrifugal fans provide consistent airflow at high pressure, making them essential for industrial processes, dust control, and material handling.

Radial Blade Fans

Radial blade centrifugal fans are ideal for handling high-volume airflow with moderate pressure, making them suitable for ventilation, air blower fans, and cooling applications. Also, their design enables the movement of large volumes of air over longer distances.

These centrifugal fans are also available with a range of fan speeds from 780 rpm to 11,500 rpm, allowing for precise airflow control. With a variety of IP ratings available, including IP68, they are well-suited for harsh environments, ensuring reliable performance even in challenging conditions.

Factors to Consider When Choosing Centrifugal Fans

When selecting a centrifugal fan, it's important to consider several factors to ensure it meets your specific needs. Here are the key things to keep in mind when making your choice:

• **Pressure Requirements: **High-pressure applications, such as dust control systems, require fans with higher pressure capabilities. Backward curved or radial blade fans are ideal for generating the necessary pressure.
• Flow Requirements: The airflow needed determines the fan type. Forward curved centrifugal blowers provide high volume at low pressure, while multi-stage centrifugal blowers offer flexibility for variable airflow needs.
• Gas Consumption: Energy-efficient fans are crucial for reducing operational costs in gas-moving applications. Centrifugal air blowers optimise energy use, especially in industrial systems.
• Inlet Temperature: Ensure the fan can handle the temperature of the incoming air. Fans with the right materials, like IP-rated fans, are ideal for high-temperature environments such as cooling systems.
• Ambient Temperature: Fans need to be durable enough to operate in the ambient temperature of the environment. IP68 centrifugal fans are designed to withstand extreme conditions, including outdoor and dusty environments.
• Operating Altitude of the Blower: At higher altitudes, lower air density can impact fan performance. Choose a fan designed to compensate for this, ensuring consistent airflow and efficiency in high-altitude applications.

Where Are Blower Fans Used?

Blower fans are crucial for efficiently moving air or gases, providing the necessary airflow for a variety of applications. They are widely used in systems requiring ventilation, cooling, or air exhaust and are essential in processes such as drying and material handling. Additionally, blower fans help maintain optimal air circulation in both residential and commercial environments, ensuring consistent performance across a range of industries.

How it is applicable in various systems in Australia:

• HVAC systems
• Dust control
• Pressure Blowers
• Air Conditioners
• Vacuum cleaners
• Air conveyor systems

What is the Difference Between a Centrifugal Fan and an Axial Fan?

Axial fans are designed for high flow rates and low pressures, with airflow moving parallel to the fan's axis. The blades of these fans come in various shapes, such as aerofoil, sickle paddle, and various pitches. They are commonly used for cooling and ventilation.

In contrast, centrifugal fans change the direction of airflow twice: first when it enters the fan and again when it exits. These fans have paddle blades, forward curved blades, backward curved blades and radial blades. Centrifugal fans move air radially. The airflow created passes through a system of tubes or ducts which creates a higher pressure airflow. This feature makes centrifugal fans ideal for high-pressure applications such as cooling and heating systems, dust control, transporting materials and air conveyor systems.
