Axial Fans

Axial fans are a type of fan that consists of a single-bladed impeller encased in a plastic or metal cage. They draw air in and propel it forward at the same axis, and the designation "axial fan" covers any type of fan by this design. Axial is the most common type of non-industrial fan and is often used in the design of most floor and table fans.

Their primary purpose is to serve as a cooling fan often included as part of a bigger system to cool machinery down during and after use. But beyond this function, they are also used to change airflow. These axial flow fans can either propel or suck air throughout a system, depending on which way the impeller's blades spin. This makes them highly versatile and suitable for HVAC systems, which is why axial flow fans are also commonly used to accelerate the flow of air in HVAC systems.

Given their versatility, axial fans can also be found in applications beyond electronics. As such, they come in a wide array of sizes, typically from 12 inch to 24 inch, and voltage requirements. RS New Zealand carries axial fans for a variety of functions, including cooling fans for heavy machinery in industrial settings down to CPU units.

Choosing the Right Cooling Fan

If you are building a custom server cabinet, CPU, or other units with mechanical hardware that produces a lot of heat, you will need to include at least one cooling fan in your build. Choosing the right axial fan for your build depends on the following:

• The space available;
• How much heat your build generate;
• What power supply is available.

You can filter the selection of axial fans RS New Zealand offers by several parameters, including:

• Size: Such as 80mm fans and 60mm fans.
• Power Consumption: Such as 5v fans, 12v fans, and 24v fans.
• Current: Includes DC fans or AC fans.

**Types of Axial Cooling Fans **

Choosing the appropriate axial fan is crucial for the effectiveness of your ventilation, cooling, or air-con system. Familiarising yourself with the various types of axial fans can also help you to make an informed choice, and here are some of the common types of axial fans available in New Zealand:

Tube Axial Fans

Tube axial fans are characterised by their cylindrical shape, making them ideal for moving air through ducts. Commonly used in industrial and commercial settings, these fans are designed for higher pressure capabilities, which makes them suitable for systems with extended ductwork.

Vane Axial Fans

Vane axial fans resemble tube axial fans, but they include guide vanes. These guide vanes are positioned behind the propeller, and they help straighten the airflow and minimise turbulence. This design enhances efficiency and makes vane axial fans ideal for high-pressure applications.

Propeller Fans

Propeller fans are the most basic and widespread type of axial fan. They consist of a motor and a propeller and are commonly used for general ventilation in both residential and commercial settings. These fans are effective at moving large volumes of air at low pressure.

High-Temperature Axial Fans

High-temperature axial fans are specifically engineered to function in high-temperature environments and are constructed with heat-resistant materials. They are frequently used in industrial processes that generate substantial heat, such as steel manufacturing and power plants.

Variable Pitch Axial Fans

Variable pitch fans are distinguished by their ability to adjust the blade angle while in operation. This feature allows for flexible control of air volume and pressure, making them perfect for applications with varying airflow requirements.

Mixed Flow Fans

Mixed flow fans are hybrids that combine the characteristics of axial and centrifugal fans. They generate higher pressures like centrifugal fans while retaining the efficiency and compact design of axial fans. This makes them ideal for applications requiring medium pressure and flow rates.

Benefits Of Axial Fans

Axial fans offer a number of distinct advantages in both industrial and residential settings.

• Precise Temperature Control: With their horizontal windmill configuration, axial fans are capable of deeply and efficiently circulating air through spaces, allowing for precise temperature control.
• Efficient: Axial fans also operate at lower pressures than comparable blowers yet move larger volumes of air, making them an ideal choice for applications like air conditioning systems for cooling factories, vents, or large equipment.
• Versatility: Axial fans are versatile enough to act as different types of exhaust fans, such as inline exhaust fans or extractor fans.

This is why axial fans are becoming an increasingly attractive option for those looking for highly efficient airflow solutions.
