Specification text

Sound attenuator splitters used for the reduction of fan noise and air-regenerated noise in air conditioning systems. Attenuation effect due to absorption. Energy-saving as well as hygiene tested. The installation kit consists of an aerodynamically profiled frame (bullnose radius of 20 mm) and sound absorbing material. The splitter frame reduces pressure losses and air-regenerated noise. The special profile helps to reduce the weight and increase the rigidity of the splitters. Frame edges are folded to protect the sound absorbing infill. Insertion loss and sound power level of air-regenerated noise measured according to EN ISO 7235. Hygiene compliant with VDI 6022, VDI 3803 Part 1 and DIN 1946 Part 4. Suitable for 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
  • U-sheets and clamp sheets to join attenuator splitters subdivided by others.
  • Depending on the splitter construction:
  • Material
  • Splitter thickness for U-sheets
  • No. of clamp sheets
  • Screws for fixing U-sheets and clamp sheets are to be provided by others.


No. of clamp sheets per splitter joint:
H or L ≤ 750 mm: without clamp sheet
H or L 751 – 1000 mm: 2 clamp sheets (1 on each side)
H or L ≥ 1001 mm: 4 clamp sheets (2 on each side)
No. of U-sheets per splitter joint: 2
Follow the instructions in the installation manual.
