It is important to know

When choosing, it is crucial that you choose a built-in version, as this type of fan is not intended to be moved between rooms. Since it is not possible to estimate its room coverage from the available data, check before purchasing whether the information provided is sufficient for your specific use.

• The built-in design means less flexibility in changing the location of use than with a portable fan.
• Information about diameter or width is not available, so it is not possible to judge how it fits your space based on the information provided here alone.

Answers to frequently asked questions

Is this fan suitable for frequent movement between rooms?

Not really. It's a built-in version, so it's more suitable for use in a permanent location than for regular transportation.

Is it possible to estimate from this data how large a space it is suitable for?

Not reliable. The available data does not include diameter or width, so the coverage of the area cannot be judged on this basis alone.
