Hello, sorry no idea, see the Dyson website.

Unfortunately, I don't know either, but what I do know is that the appliance produces a lot of warm air, which you don't really want in summer. What's more, the air flow isn't incredibly high. In my opinion, it produces a lot of heat and noise. That's why it's been in our cellar for a few years now. We bought a rather inconspicuous DC ceiling fan instead. It's quiet, the air flow is enormous (if you want it to be) and the power consumption is just under half.
And if a ceiling fan doesn't suit you, I think any standard fan is better/more pleasant in terms of price, performance and noise emissions.
