What are axial fans used for?
Axial fans are used across all industries where the cooling of components or machinery is important. Fans work by drawing air across a surface to cool it or to push hot air way to cool it. This is essential in everyday items such as a desktop PC, where the axial fan would cool down the processor to ensure the computer would continue to operate smoothly.
Common uses of axial fans
• Server racks- Axial fans are used to keep hubs, routers and patch panels cool
• Electrical cabinets and enclosures – Installed into cabinets and enclosures to cool and protect components preventing premature failure
• Production lines or areas where motors are in use constantly, prolonging gearbox and motor life
What is impedance protection?
Impedance protection is a process designed to stop the axial fan motor from overheating or causing a power surge. In a short description, the impedance protect fans will heat up to a certain point and will not increase in temperature after it reaches that point, ensuring the motor remains stable.
Benefits of ball bearings over sleeve bearings
Ball bearings are generally the more popular choice with axial fans, due to their reputation for longevity and their ability to operate in higher temperatures. Another plus is they are not limited by mounting preferences. They're able to be mounted in any axis position, which is excellent for certain designs.
