Feature

• RS Pro DC Ball Bearing Fans with Tachometer Output. Brought to you by RS Pro brand, a wide range of DC ball bearing axial fans offering a cost effective cooling solution without sacrificing on quality or reliability. With a die cast aluminium frame and a brushless, auto restart, impedance and polarity protected motor these fans are ideal for a multitude of applications. All models are highly reliable and excellent quality. Features and Benefits. Robust diecast aluminium frame, ideal for industrial applications. PBT UL94V-0 thermoplastic impeller. Ball bearing system, supporting excellent performance and life expectancy. Typically 60000 hours based on L10 curve figures. Brushless DC, polarity protected, locked rotor protected motor. Tachometer output options, for sensing and speed control. Applications. Axial fans are used across all industries where the cooling of components and equipment is essential. Fans work by drawing air across a surface to cool it or to push hot air away to cool it. Some of the most common uses for DC axial fans are;. 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. Laptop and Computer towers – Compact DC fans are ideal for incorporating into computers and equipment. Due to their small frame size and depth. Does this fan use ball bearings or sleeve bearings . This range of axial fans uses ball bearings. Although both are suitable for virtually the same applications, ball bearings are the more common choice. This is mainly due to their longevity and the ability to be mounted and draw/push air in any axis position. What kind of safety features are available with this fan . The polarity protection provided with the motor ensures a smooth and consistent operation. A polarity issue can cause the motor to fail, overheat or be internally damaged. Thankfully, this RS Pro series of axial fans protects against this outcome. This axial fan also includes a locked rotor and an auto restart, protecting the impellers for too much movement, and if a failure happens, it will automatically reboot. What is an Axial Fan . An axial fan is a type of fan commonly used within everyday applications, such as air conditioners and computers. It causes both air and gas (depending on the application) to flow directly through it in an axial direction at different speeds. Allowing the air flow to be axial and both entry and exit. The most common versions tend to have fewer impeller blades than conventional duct fans or centrifugal fans which have similar operations.
