SIEGENIA AEROMAT MIDI - supply air element integrated in the box 

The secret of Aeromat Midi's success lies in its intelligent design with double locking mechanism. The volume flow limitation is another convincing feature. With these clever details, the natural pressure difference enables an air exchange that reliably fulfils the fresh air requirement, regardless of the user. Aeromat Midi can be used in particular as an air outlet for a central exhaust air system. The ventilation module consists of the passive Aeromat Midi supply air element and the specially developed Beck+Heun mounting frame. The latter is used to integrate the supply air element into the inner leg of the roller shutter box.

1. mounting frame

This is used for room-side plastering (13 mm projection over the box surface) and is pre-mounted in the roller shutter box including the weather limb. In addition, an insulation core is integrated between the fan and the outer weather lug.

2. ventilation element

The ventilation element is installed after plastering.
