Functional description

Splitter sound attenuators of Type XSA contain splitters of Type XKA.

The attenuation effect of the XKA splitters is due to absorption.

The splitters have a mineral wool infill as absorption material.

The length (L) of splitter attenuators refers to the airflow direction.

Quick sizing tables provide a good overview of the insertion loss and of differential pressures for different airway widths and airflow velocities. Intermediate values can be calculated with our Easy Product Finder design programme.

The sound power levels L_WA apply to sound attenuators with a cross-sectional area (B × H) of 1 m².

The differential pressures apply to sound attenuators with a height of 1 m.

Installation details, Basic information and nomenclature

Upstream conditions after bends, junctions or a narrowing or widening of the duct, vertical upstream section, splitters upright

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 protection against the effects of weather

Principal dimensions

ØD [mm]

Outer diameter of the spigot

ØD₃ [mm]

Outer diameter of circular silencers

L [mm]

Length of attenuator/silencer including spigot (in airflow direction)

L₁ [mm]

Length of acoustic cladding and acoustically effective length

B [mm]

Attenuator width and duct width (upright splitters)

H [mm]

Attenuator height and duct height (upright splitters)

T [mm]

Splitter thickness

S [mm]

Airway width

n [ ]

Number of flange screw holes

m [kg]

Weight

Nomenclature

f_m [Hz]

Octave band centre frequency

L_WA [dB(A)]

A-weighted sound power level of air-regenerated noise

D_e [dB]

Insertion loss

V [m³/h] and [l/s]

Volume flow rate

Δp_st [Pa]

Static differential pressure

All sound power levels are based on 1 pW.

All values were measured in a TROX lab and to EN ISO 7235. Intermediate values may be achieved by interpolation.

Lab measurements exceeding 50 dB are indicated as 50 dB, in line with common practice.
