Cata Duct in Line and SMT ventilation fans can be used to achieve extremely quiet ventilation by not placing the unit flush with the wall or ceiling of the room to be ventilated. In general, it is recommended to install it above a false ceiling, in an attic, in a mechanical room or in other places where the noise level resulting from the operation of the fan is less disturbing to the user.

The fan is excellent for ventilating bathrooms, restrooms, and household rooms, and for removing humid air in cases where the fan cannot be placed on the side wall or ceiling of the room to be ventilated for some reason, or if the user wants to create the quietest possible ventilation solution.

The fan can be installed in a pipe gap, so it can be placed almost anywhere in the pipe system formed between the extraction point and the outlet point to the outside. The pipe connections of the fan can be easily disconnected from the fan body, which facilitates the installation of the fan, as well as the recommended 1-2 times a year cleaning process.

The radially designed impeller of the two-speed versions enables efficient extraction even with longer pipe systems if installed professionally. In the case of versions with two speed levels, it is advisable to select the level that suits the installation conditions and user needs during installation.
