System for treating air in building interiors, and ventilator device

A system for treating air in a building interior, the system comprising at least one ventilator module which comprises:

• a housing comprising,
• at least one upper face which comprises at least one opening,
• a lower face which is arranged opposite to the at least one upper face, the lower face comprising a housing base which is designed as a stand surface for positioning the at least one ventilator module,
• at least one housing wall which extends between the at least one upper face and the lower face, and
• at least one lateral outlet opening arranged on the at least one housing wall in a region which is adjacent to the lower face;
• a flow channel formed in the housing between the at least one upper face and the lower face;
• a drive motor arranged in the housing;
• and
• at least one impeller which is configured to rotate about a rotational axis and to be driven by the drive motor so as to convey an air flow between the at least one upper face and the lower face.

A ventilator device for accelerating air in a building interior, the ventilator device comprising:

• a housing comprising,
• at least one upper face which comprises at least one opening,
