ARX CeraDyna Series Axial Fan, 12 V dc, DC Operation, 21.6m³/h, 2.04W, 170mA Max, 40 x 40 x 20mm

TUV. The lead lengths range from 245mm ± 10mm to 295mm ± 10mm. Red is +ve, black is -ve. The output wire is either white or yellow (if fitted). The O/P wire need only be connected if user wants to measure the speed of the fan (1 revolution gives 1 pulsed output signal generally). ARX DC Ceramic Bearing Axial Fans. Brought to you by ARX, a wide range of DC ceramic bearing axial fans offering cost effective cooling and ventilation solutions without sacrificing on quality or reliability. Ceramic bearing internals ensure a massive increase in longevity. All models are highly reliable and excellent quality. Features and Benefits. Quiet operation Increased performance Fully resistant to heat and humidity No use of oil as lubricant Low friction and self polishing. Does this fan use ball bearings or sleeve bearings?. This range of axial fans uses neither. A ceramic bearing is provided which has been testing to be both a more cost effective build and longer lasting than a standard ball or sleeve bearing fan. Highlights include the quiet and smooth operation and virtually static free due to very low friction. What kind of safety features are available with this fan?. As standard with this range of ARX axial fans, reverse voltage protection is provided. Ensuring no damaging or potentially dangerous outcomes from an electrical surge. What can an axial fan be used with?. 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. 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.
