DACKA-AOpenable duct attenuator with removable baffles

DACKA-A is an openable duct attenuator in galvanized steel* with splitters filled with Acutec® attenuation material. Splitters are removable for cleaning or replacement.

Acutec® is a hygienic and washable polyester absorption material with high airflow and shock resistant non-woven fleece finishing and no loose fibres.

Bigger attenuators are reinforced by an outer modular frame.

Connection frame possibilities: IT- (LS), EURO-20 (RJFP-20) or EURO-30 (RJFP-30).

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

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

Tested according to ISO 7235 standard.
