Axial fans (DC/AC)
Axial fans are used to create a straight and efficient airflow along the fan's axis of rotation and are one of the most common solutions for cooling and ventilation of electronics, enclosures and machinery. They are particularly suitable for applications where large volumes of air need to be moved with relatively low back pressure. Swelex offers axial fans in both DC and AC versions, with a wide range of sizes, voltages and performance levels to suit everything from simple cooling needs to more demanding industrial applications.
Advantages of axial fans
- High airflow in relation to size
- Compact and lightweight design
- Energy-efficient solutions for continuous operation
- Low noise levels when correctly dimensioned
- Wide range of standard and specialised versions
Options and customisations
Axial fans can be supplied with a wide range of accessories and customisations, such as:
- PWM or voltage control
- Temperature control
- Alarm and monitoring functions
- IP rated versions
- Protective grilles, filters and mounting hardware
DC axial fans
DC fans are energy efficient, quiet and easy to control. They are ideal for applications where low energy consumption and precise speed control are important. DC axial fans are widely used in:
- Electronics and control systems
- Medical devices
- Telecoms and IT
- Battery packs and charging systems
AC axial fans
AC axial fans are robust and suitable for continuous operation in industrial environments. With a simple electrical design and high reliability, they are often used where AC power is available and where long life is prioritised. Common applications are:
- Industrial enclosures and cabinets
- Machinery and production equipment
- Power and energy systems
- Outdoor applications

- Robust construction for continuous operation
- Easy maintenance and smooth integration
- Long lifetime up to 50 000 hours
AC axial fans
AC axial fans are used for efficient cooling of electronics and machinery. The airflow is parallel to the fan axis, providing stable and directed air circulation.
- High static pressure capacity
- Brushless motor for low maintenance requirements
- Plastic impeller (UL94V-0), aluminium frame
- Operating temperature: -10°C to 70°C
- Long lifetime up to 50 000 hours
FAQ - Frequently asked questions about Axial fans
What is the difference between DC and AC axial fans?
- DC fans are powered by direct current and often provide higher efficiency, quieter operation and easier speed control.
- AC fans are powered by alternating current, are robust and suitable for standard mains voltage without additional electronics.
How do I choose the right fan size?
- Determine the flow requirement (m³/h or CFM) and static pressure (Pa) for your application.
- Check the fan voltage and power for compatibility with your installation.
Are the fans quiet enough for offices or laboratories?
- The noise level varies depending on size, speed and design. Choose a fan with a low dB level or a silent version for sensitive environments.
Can they be used outdoors or in humid environments?
- Some models are IP rated and can withstand moisture, dust and light liquids. Always check the IP rating and specifications for your environment.
