Important notes
Information on the installation manual
This manual enables operating or service personnel
to correctly install the product described below and
to use it safely and efficiently.
It is essential that these individuals read and fully
understand this manual before starting any work.
The basic prerequisite for safe working is to comply
with the safety notes and all instructions in this
manual.
The local regulations for health and safety at work
and general safety regulations also apply.
Safety
Correct use
Splitter sound attenuators and sound attenuator
splitters are used to reduce fan and air-generated
noise in ventilation and air-conditioning systems,
e.g., in AHUs or ducts.
Use in potentially explosive atmos-
pheres according to EU Directive 2014/34/EU
(ATEX)
Splitter sound attenuators of the types XS and
MS, as well as sound attenuator splitters of the
types XK, MK and RK, may be used in Ex-areas
of zone 1, 2 and zone 21, 22 (outside) according
to Directive 1999/92/EC.
Observe the following instructions for use:
–Maximum operating temperature 100 °C
–Maximum airflow velocity up to 20 m/s
–Electrically connect the sound attenuator
splitter with the casing.
–Earth the splitter sound attenuator!
–To prevent dust deposits, clean sound
attenuators and splitters regularly!
–When cleaning, ensure that the sound
attenuator / sound attenuator splitter does
not become statically charged!

Upstream section
NOTICE!
Damage due to turbulent airflow!
If a turbulent flow occurs at the sound attenuator,
this can lead to damage of the sound attenuator
splitter.
Therefore, a straight upstream section must be
provided in the airflow direction upstream of the
sound attenuator.
The minimum recommended upstream section is
calculated depending on the change of direction,
cross-section change and splitter arrangement;
see Figures Fig. 5 – Fig. 8

Suspension
Fig. 9: Full-surface contact points
When installing the sound attenuator horizon-
tally, choose a load-bearing construction that
supports the entire width of the casing (B). Two
full-surface contact points per component are
to be provided.
The sound attenuator must not be installed
exclusively vertically on the duct profiles or ver-
tically in the airflow direction.
Flanges and connection
The flange must be connected to the duct system at
all connection points using suitable connecting
material. Flanges have four connecting holes, one
per angle. The angle section frame (W) has a dif-
ferent number of connecting holes depending on
the dimensions. Suitable matching frames are avail-
able in the TROX delivery programme and are
screwed to the sound attenuator, if ordered. When
connecting the splitter sound attenuator to the duct
system, a seal/sealing kit (by others) must be pro-
vided.

Matching frame
Detach the matching frame from the sound attenu-
ator. Install the matching frame to the duct (pro-
vided by others) using suitable fixing material. Fix
cover angles (provided by others) to reduce frame
leakage. Recommended dimensions for cover
angle: total length = B - 17 mm, leg length of angle
10 x 30 mm.

Subdivided splitter sound attenuators (MS, XS)
Splitter sound attenuators with a duct casing are
supplied in one piece up to a length of 1500 mm.
Longer constructions (L >1500 mm to 3000 mm)
are supplied in two segments, which must be
installed by others. In the process, a seal must be
provided between the two parts (not included in the
supply package).
For type MS with length subdivision, make sure that
the splitters are arranged correctly

mentary installation details for splitter sound attenu-
ators types MS-OL and XS-OL’ on page 10.

length

In addition to the length subdivision, subdivisions in
width (B) and/or height (H) are possible. Each
measurement can be subdivided only once. Splitter
sound attenuators with width and/or height subdivi-
sion are constructed with angle section frames (W).
Width subdivision - B >2400 mm to 4800 mm
Height subdivision - H >1800 mm to 3600 mm.
Before assembling height- and/or width-subdivided
splitter sound attenuators, remove the transport
protection devices (unperforated).

The screw connection is supplied in drawstring bag
and includes, for each connection:
1 units - Hexagon head screw M8x25 8.8 A2J

Supplementary installation details for splitter
sound attenuators types MS-OL and XS-OL
Splitter sound attenuators without a casing are
called splitter installation kits (OL).
According to the order code, the installation kit con-
tains a certain number of splitters that can be
installed in rectangular ducts (provided by others)
with smooth plane-parallel walls.

Arrangement of the splinters:
Install the splitters parallel at a defined distance
(S = gap dimension) to each other. Splitters of the
same length L are arranged parallel next to each
other.
