Analysis of the difference between refurbished and original cooling fans

I believe that many customers will ask the seller if they are the manufacturer when inquiring about the cooling fan. Generally, there are two reasons. First, the cooling fan sold directly by the manufacturer is definitely cheaper than the trader; second, the fan sold by the manufacturer is original. It will be a refurbished machine. Automobile radiator fan factory is a cooling fan manufacturer with years of Ru0026D and production experience. Now I will explain to you how to distinguish between refurbished fans and original fans, for customers to use as a reference when purchasing cooling fans. First, let’s take a look at the trademark: the original cooling fan’s trademarks are all exquisitely printed, with uniform colors, and the printed handwriting is clear and shiny, and has a sense of relief; while the refurbished fan’s trademarks are informal and the printing quality is poor, often with background colors. There will be different shades, and the handwriting will not be prominent, and the color will be scratched off the surface of the trademark with a few fingernails, while the original trademark will not be affected by scratching with your fingernail. Secondly, check the fan blades: the surface of the fan blades of the original cooling fan will show a matt effect, and you can see fine and uniform particles against the light, and it feels rough to the touch; while the refurbished fan will be exposed to the air for a long time. With friction, the particles on the surface of the fan blade are gone and become smooth, and you can see the traces of the use of rubbing. Finally, there are mounting holes: the refurbished fans are all used, so there will be traces on the mounting holes. If it is self-working screws, threads will be left in the holes, if it is fixed with screws and nuts Will leave indentation of the nut around the hole.
