DACKA is a rectangular duct attenuator in galvanized steel* with splitters filled with Acutec® attenuation material.
Acutec® is a hygienic and washable polyester absorption material with high airflow and shock resistant non-woven fleece finishing and no loose fibres.

Attenuator is equiped with joining profile IT (=LS), EURO-20 (=RJFP20) or EURO-30 (=RJFP30).

Attenuators can be ordered with splitters protected by perforated plate; additional thermal insulation 50mm (LE50) or more and with fire insulation on request.

Attenuators with TO empty section are available with inspection hatch. Fully cleanable and openable attenuators you will find in the product range: DACKA-A.

To calculate the attenuator you can use our IT-online tool LindQST or DIM-silencer, where splitter distance, length and height can be optimized for the best perofmance.

Tested according to ISO 7235 standard.
