FIELD: ventilation.
SUBSTANCE: invention relates to a ventilating device, especially for an electrical cabinet. Technical result is achieved by the fact that the ventilating device comprises a fan support for a fan having a frame with an opening through which a flow of gaseous medium flows during operation and which forms a receiving region adapted to accommodate various replaceable inserts including a valve device, and having at least one fastening means for fixing the corresponding insert. Fan holder also includes a detachable cover whereby the receiving region of the fan holder is closed from the outside and which has a front grill in the form of a diffuser and having a plurality of piercing splines with an elliptical cross section. Valve assembly has a valve frame that is inserted into the receiving region of the fan holder and carries at least one valve. Longitudinal axis (L) of the groove slots is oriented substantially parallel to the valves in the open state.
EFFECT: creation of a ventilation device that provides efficient cooling with minimizing the aerodynamic resistance created by the device.
