I have just bought the Air 4000. Does it also make such howling noises in automatic or low mode? (as soon as the speed is increased, the fan drowns out the howling noises)

I feel the same way.

Were you able to find out anything?

I can't confirm that. We run the appliance in various modes without it getting particularly loud.
