Aerodynamically optimised splitter frame

SPLITTER WITH HIGH INSERTION LOSS WITH BROADBAND ATTENUATION EVEN IN THE LOW FREQUENCY RANGE

Sound attenuator splitters, installation kit to be used in ventilation and air conditioning systems

Attenuation effect due to absorption
Energy efficient due to aerodynamically formed frame (bullnose radius 20 mm)
Acoustic data measured to ISO 7235
Sound absorbing material is biosoluble and hence hygienically safe
Sound absorbing material faced with glass fibre fabric as a protection against erosion due to airflow velocities up to 20 m/s
The sound absorbing material is non-combustible, to EN 13501, fire rating class A1
For use in areas with potentially explosive atmospheres (according to EC Directive 2014/34/EU (ATEX)), zones 1, 2, and zones 21 and 22 (outside) according to EC Directive 1999/92/EC
Operating temperature up to 100 °C, with expanded metal (variant L) up to 300 °C for a limited period of time

Optional equipment and accessories

Expanded metal as an additional mechanical protection for the sound absorbing material
Stainless steel variant A2 (1.4301), with optional perforated metal facing as an additional protection for the sound absorbing material
Other stainless steel and aluminium variants as well as PUR coating upon request
U-sheets and clamp sheets to join subdivided attenuator splitters

Parts and characteristics

Aerodynamically profiled frame
Reduced weight and increased rigidity due to special profile
Helps to optimise the airflow, hence reducing the airregenerated noise
Reduces the pressure loss
Covers the edges of the sound absorbing material
Sound absorbing material fitted to reduce air-regenerated noise by absorption

Accessories

UU-sheets/clamp sheets to join subdivided attenuator splitters (included with subdivided splitter constructions)

Construction features
Aerodynamically formed splitter frame (bullnose radius 20 mm) that helps to reduce turbulence on both the upstream and downstream sides; frame with grooves for increased rigidity

Frame edges are folded to protect the infill
