After 15 years in the house, I might know this but... this fan that's sitting on the roof ventilating the house, is it eternally maintenance-free or not?
Best answer
It may not have eternal life, but this engine type is durable and can run 24/7 for 20-25 years without significant service.
Noise may then occur due to worn bearings. It can also stop rotating if the run capacitor gives out.
No expensive parts to replace, maybe 200-300 kr.
