Splitter sound attenuators type MS contain splitters type MK.
The attenuation effect of the MK splitters is due to absorption and resonance. The splitters have a mineral wool infill as sound absorbing material. Part of the splitter surface that runs parallel to the airflow is covered with resonating panels. These panels start oscillating due to the sound (resonance) and hence absorb sound energy. Resonance works best in the frequency range of critical fan noise. There is a higher attenuation across a wider frequency range when compared to mere absorption splitters.

Installation and commissioning

1 Sound attenuator, with width and height subdivided
2 Seal
3 Screw fix connection

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: 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
