Individual room climate at low costs

Utilise our far reaching experience...
FassadenSystemLüftung (FSL) has been developing decentralised ventilation systems since 1975. When quiet, individual room conditioning is required, and when the investment costs and space required by central air conditioning systems are too high, then our products and system solutions come into their own. Using the ventilation devices integrated into the outer skin of the building, fresh air is supplied to the rooms and return air is extracted. From simple flow devices to complex systems, numerous variants can be realised.


...link to new opportunities and innovations...

FSL has been part of the TROX Group since 2000. In conjunction with the market leading manufacturer of ventilation systems and components in Europe, FSL can draw on significantly higher production capacity, a world-wide sales network, as well as the most capable research and development division in the sector - a constellation from which you as a partner can only profit.


...and in this way create a natural and healthy living environment for yourself

Our many references and loyal, satisfied customers reflect the good collaboration between FSL and its partners and customers, for whom we often meet the most individual of wishes.

Experience in almost all application areas makes it possible for you to draw on our ideas, developments, products, and concepts. This applies both for the new buildings, as well as during renovation work. When quiet and individual room air conditioning is required, and when investment costs and space required by central air conditioning are too large, then our products and system solutions come into their own.
