Ventilation inlet module, ventilator and method for operating a ventilation device

The invention relates to a ventilation inlet module (10) comprising a box-like filter module (12, 32) through which air can flow and which has an inlet and an outlet opening, as well as a frame (14, 36, 72) surrounding it, wherein the filter module (12, 32) is connected to the surrounding frame (14, 36, 72) in an airtight and movable (16, 42) manner. A vibration device (18, 44, 78) is provided in order to effect a jerky movement of the filter module (12, 32) relative to the surrounding frame (14, 36, 72), so that any dirt particles possibly located in the filter module (12, 32) fall out. The invention also relates to a ventilation device (30, 70) with a ventilation inlet module (10) according to the invention as well as a method for cleaning a ventilation device (30, 70).
