I need to replace an extractor fan, but I don't know how much of a choice I have when it comes to the replacement.
Currently, I have this model, mounted to the ceiling: https://www.vortice.ltd.uk/shop/residential-ventilation/ariett/ariett/. I don't have access to the roof (5th floor), but I unscrewed the fan, and I can see that the air is pushed to the space between the ceiling and the roof. The roof has a ventilation/exhaust pipe, but there's no ducting connecting to the fan.
The current model I have is centrifugal. Does it mean that the replacement should be also the same type? If so, any recommendations?
