The In-the-Wall is available in two versions. Fully built into the wall with a mounting depth of 204 or 219 mm. For thinner walls there is the semi-In-the-Wall with a mounting depth of 134 mm.

The Compac In-the-Wall is also available as an ‘Everywhere’ version. This offers the possibility of extracting air in a different room than where the device is mounted. By connecting the fan to a pipe to the bathroom and/or toilet, decentralised WTW works just like central WTW, but without supply pipes in which dirt can accumulate that pollutes the incoming air. The In-the-Wall can be fully built into the wall. The choice of location is more flexible and can therefore be closer to the wet room and/or the room where fresh air is desired. Also available as an On-the-Wall version.
