- Sizes from 2401 – 4800 mm are available with the width subdivided in increments of 1 mm
  - Even no. of splitters: centre division
  - Odd no. of splitters: off-centre division

Height H: 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800 mm
- Intermediate sizes 150 – 1799 mm in increments of 1 mm
- Sizes from 1801 – 3600 mm are available with the height subdivided in increments of 1 mm
  - Centre division

Length L: 500, 750, 1000, 1250, 1500 mm
- Intermediate sizes 501 – 1499 mm in increments of 1 mm

Sizes from 1501 – 3000 mm are available with the length subdivided in increments of 1 mm
- Part L1: 1000, 1250, 1500 mm
- Part L2: at least 501 mm and ≤ L1, in increments of 1 mm

Width and/or height subdivided if B + H > 4200 mm

Airway width S
- Minimum: splitter thickness T × 0.25, but not < 40 mm
- Maximum: splitter thickness T × 2

The weight of a splitter sound attenuator is determined by the number and costruction of the splitters and ducts.

Weight [kg] = (weight of splitter x no. of splitters) + duct

Schematic illustration of subdivided sound attenuators

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 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
