That's an impressive looking fan, much better built than modern stuff.
Most of which was dead skin.The fan and housing were full of dust.
Don't let it get so clogged again.Cleaned the fan and popped it back in. It runs as good as new and probably shifts a lot more air now.
If you're married, warn your wife that we have voted to move to Ukipitopia, where she will officially be termed a slut if she doesn't clean that properly.
I am not sure why air resistance decreases as volume extracted increases.
But neither axis has a time scale...I was making the mistake of think the graph was over time.....
All the bathrooms are in line and have a shared ventilation shaft. Ours being at the top. So the extractor of the bottom flat would perform worse compared to a top floor flat.
Yes, but...That is why I asked the question, as I knew I had interpreted it wrong.
