ECTA 100

ECTA 100

The ECTA rectangular sound attenuator strongly attenuates low, mid and high-frequency noise propagation in rectangular ducting.
ECTA 100
ECTA 100
The ECTA rectangular sound attenuator attenuates noise transmitted in the ventilation ducting and therefore ensures acoustic comfort inside non-residential and multi-occupancy residential buildings. The baffle is 100 mm or 200 mm thick and its L x H dimensions may be between 300 and 2400 mm.

The ECTA comprises a single-piece panel made of 100 mm or 200 mm thick mineral wool which strongly absorbs noise. To maximise attenuation, several should be installed in series inside a ducting element.

  • thickness 100 mm or 200 mm,
  • dimensions (L and H) from 300 to 2400 mm.
  • single-piece panels made of mineral wool,
  • density: 40 kg/m3,
  • black anti-flocking glass mat, 1 mm thick in standard range (available on request: glass fibre for sterile rooms or perforated plate for high pressure and speed applications),
  • galvanised steel frame, standard thickness 6/10° (available on request: 304 or 316L stainless steel),
  • available on request: complete unit including the housing, riveted baffles and METU type connection frame,
  • M0 fire certification, or A1 under Euroclass ratings,
  • version tested to 400°C - 2 hours up to 10 m/s,
  • Class B air tight properties as per EN 1751 (class C on request).
  • installed in series in a rectangular ducting element,
  • install between slides for better performance management,
  • delivered as complete unit.
