DACKA-A is an openable duct silencer 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 silencers are reinforced by an outer modular frame.
Connection frame possibilities: IT- (LS), EURO-20 (RJFP-20) or EURO-30 (RJFP-30).
Silencers 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 silencer you can use our IT-program DIMsilencer, where splitter distance, length and height can be optimized for the best performance.
Tested according to ISO 7235 standard.
