It was 40º (104º Farenheit) in here Melbourne the other day, and we needed a fan in the house.
So we bought a Delonghi, (bottom) which is ok to look at, being all metal. But it sounds like a B-52 roaring past. Maybe there are too many tines in the guard for the air to rush over? Maybe the edge of the blade is too thin, making it swoosh like a sword?
I dont know, but I do wonder if the classic Peter Behrens AEG ventilator is as quiet as it is iconic?
Somehow I think so. I see the early version has no guard at all!
