B Width of the sound attenuator

H Height of the sound attenuator

Installation and commissioning

Follow the installation information and comply with the general codes of good practice in order to achieve the given performance data
Up to height H = 1200 mm: 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
Installation in ducts outside of closed rooms requires sufficient pection against the effects of weather
