Type CFE crossflow elements can be installed in lightweight partition walls. Due to the pressure difference, the air flows e.g. from the office area as exhaust air into the hallway, into indoor zones or neighbouring areas with suspended ceilings. A central exhaust air system can be used there. Integrated acoustic lining reduces noise transmission into adjacent rooms. To avoid sound transmission on lightweight walls, insulation strips are attached to the casing for sound decoupling.

Specification text

Crossflow elements with cross talk silencers are used for air transfer flow into adjacent rooms and are suitable for comfort areas.

The crossflow element is available in rectangular Z or T design. The nominal height and nominal length are variable within the limits in mm steps. Therefore, the crossflow element can be optimally adapted to project-specific requirements.

The design without recess for an air diffuser offers builders and architects, in compliance with the free cross section of 51%, various design options. For the version with recess for an air diffuser, a choice can be made between different diffuser fronts. The perforated diffuser face -PP has a free area of approx. 51%. The hole diameter is 6 mm, staggered pitch.

Fixing a diffuser face to the crossflow element after the drywalling has been completed is quick and easy.

The crossflow element includes a cross talk silencer with acoustic lining that reduces noise transmission to adjacent rooms. To prevent sound transmission via the casing, sealing strips are attached to the crossflow element.

Suitable for the space saving or concealed installation in lightweight partition walls with different stand widths.

Sound power level of the air-regenerated noise measured according to EN ISO 5135.

Sound reduction index according to DIN EN ISO 10140 and DIN EN ISO 717-1.

Crossflow element and diffuser face made of galvanised sheet steel.

Sound insulation material made of mineral wool.
