Air-Stream – stainless steel air-exhaust system
The concentric flue gas system Air-Stream meets high requirements with its appearance and versatile areas of application and is preferably used as a complete solution for indoor or outdoor use.
This is a double-shell system with an annular gap between the flue gas-carrying inner pipe and the statically supporting outer pipe.
For room-air-independent fireplaces, the combustion air is drawn in from outside through the annular gap.
It is easy and quick to install and can be shortened on site without affecting the appearance or the intended use. The integrated spring spacers always ensure secure centring of the inner tube.
Numerous components and the extensive range of accessories from the proven Raab DW systems ensure simple planning and rapid construction progress.
Air-Stream is particularly suitable for modern heat generators with high efficiency, such as calorific value boilers. The room-air-independent mode of operation prevents heat extraction within the building envelope.
