Still more noise and vibrations and in extreme case even a total malfunction – this is a typical “end” of the fan after a long-time operation in a dusty or corrosive environment. In a usual dry and relatively clean environment, this scenario is not that dramatic and high-quality fans hold on to work for many years without problems. However, it can be also said, that common industrial environment is quite far from an ideal = clean one.
So, which fan to use?
The first good advice might be to use a quality fan, for example from companies Sunon or EBM-Papst. Company Sunon this time declares, that they shifted a level of lifetime and durability a step higher…
They “wrapped” all the motor into a „high-tech“ coating and incorporated a mechanism for automatic dust removal from a motor part.
And the result?
The fan works reliably even after a 60 minute ingress into water and into 1m depth. That´s only a small example demonstrating features of the new series with IP68 protection. New series carry GExxxx or GFxxxx marking and they´re available in three sizes - 80x80x25mm, 80x80x38mm and 90x90x25mm. All types are equipped by two ball bearings.
