Cata UC (ultra comfort) type ventilation fans are characterized by a much lower noise level (26 dB/A/) compared to their counterparts with similar performance and traditional design. The front panel can be easily removed or it can be placed back on the device, which enables the fan to be easily and efficiently cleaned, and for versions with post-ventilation and humidity sensor, to carry out and modify the settings.

Thanks to the built-in butterfly valve, unwanted backflow can be prevented, which can be particularly beneficial in the case of restrooms and multi-user ventilation systems (e.g. the common line of apartment buildings).
Thanks to its special bearings, it can be installed both in the wall plane and in the ceiling.

Timer function: enables a delayed shutdown of the fan. The desired post-ventilation time can be set steplessly between 1.5 and 20 minutes. This function can be particularly useful in the case of ventilation of restrooms or bathrooms combined with a restroom.

Hygro function: the built-in humidity sensor unit provides automatic ventilation if the humidity in the room exceeds the permitted threshold. This value can be adjusted in 6 levels between 30-80% relative humidity, according to needs.

Adjustable speed: with the help of the built-in speed controller, the power of the fan (including the noise level) can be adjusted in 6 steps, between 1050 rpm and 2220 rpm, according to needs. Thanks to this, a smaller room (
