Splitter sound attenuator with high insertion loss, even in the high-frequency range

Splitter sound attenuator, basically a duct section with integral splitters (type XK), for ventilation and air conditioning systems

    Specification text

    Splitter sound attenuators used for the reduction of fan noise and air-regenerated noise in ventilation and air conditioning systems. Attenuation effect due to absorption. Energy-saving as well as hygiene tested and certified. Splitter sound attenuator that consist of a duct with connections and integral type XK splitters or a splitter set. Splitters consist of an aerodynamically formed frame (bullnose radius 20 mm) and absorbing material. The splitter frame reduces pressure losses and air-regenerated noise. The profiled frame with bullnose edges increase the rigidity of the splitter. Insertion loss and sound power level of air-regenerated noise measured according to EN ISO 7235. For requirements in areas with potentially explosive atmospheres (ATEX), zones 1, 2, 21 and 22 (outside) according to Directive 1999/92/EC.

    Installation and commissioning

    • Follow the installation manual and comply with the general codes of good practice in order to achieve the given performance data
    • Up to height H = 1200 mm, length L = 1500 mm and 40 kg max.: any installation orientation, but we recommend upright installation of splitters
    • From height H = 1201 mm: upright installation only
    • The length (L) of sound attenuator splitters and splitter sound attenuators refers to the airflow direction; be sure to note how width, height and length are defined, particularly in case of a vertical airflow
    • A turbulent airflow may cause damage to the splitters 
      • A straight upstream section is required upstream of the sound attenuator
      • The recommended minimum upstream section depends on the change of direction, change of cross-section and splitter arrangement
    • Installation in ducts outside closed rooms requires sufficient protection against the effects of weather
