Safety
Correct use
Splitter sound attenuators and sound attenuator
splitters are used for the reduction of fan noise and
air-regenerated noise in ventilation and air condi-
tioning systems, for example in air handling units or
ducts.
Use in areas with potentially explosive
atmospheres according to EU Directive
2014/34/EU (ATEX)
Splitter sound attenuators XS and MS as well as
sound attenuator splitters XK, MK and RK may
be used in zone 1 and 2 areas as well as in zone
21 and 22 (outside) areas with potentially explo-
sive atmospheres according to Directive
1999/92/EC.
Please note:
Max. operating temperature 100 °C
Max. airflow velocity 20 m/s
Make an electrical connection between the
splitter and the casing.
Connect the splitter sound attenuator to the
earth.
Clean sound attenuators and splitters regu-
larly to prevent accumulated dust.
Clean attenuators and splitters in such a
way that no electrostatic charge builds up.

  • Page 5 Installation Upstream section NOTICE! Risk of damage due to turbulent airflow A turbulent airflow may cause damage to the splitters. This is why a straight upstream section is required upstream of the sound attenuator. The recommended minimum upstream section Fig. 7: Horizontal airflow, splitters upright depends on the change of direction, change of cross-section and splitter arrangement, see Fig.
  • Page 6 Angle section frames (W) may have a varying number of screw holes, depending on their size. Suitable matching frames are avail- able from TROX; they come screw-fixed to the attenuator if you have ordered them. Duct connec- tion requires a seal (by others).
