Mounting version LAL 50

with warping inside the window reveal

The LAL 50 installation version guarantees perfect installation of your decentralised ventilation units in terms of building physics with horizontal distortion. The flat duct is warped to the side in the insulation layer. The air intake takes place in the window reveal.
The factory pre-assembled and two-dimensionally adjustable shell ring module set (RS-SCP LAL 50) can be integrated within a 200 mm shell opening completely free of thermal bridges.

Room ventilation "on silent soles"

SILENT COMFORT PLUS sound-insulating ventilation units have been designed with demand-led fan support and ensure an optimum supply of fresh air under particularly comfortable and energy-saving operating conditions.
This ensures highly effective noise protection around the clock, even in the event of heavy traffic and increased ambient noise.
All ventilation functions can be regulated in 10 stages directly on the room-side panel.

Final assembly set

The final assembly set consists of a thermally insulated EPP system support unit with an energy-efficient, extremely quiet-running EC fan of the latest generation and is designed for continuous operation. The ventilation system is particularly easy to install and is suitable for use in monolithic and multi-layer wall constructions as well as in timber stud constructions. There are numerous other installation options in conjunction with knee floor situations.

When designed for increased sound insulation, the construction set is also fitted with a sound insulation element.
