MINKA is a rectangular duct attenuator in galvanized steel* with baffles (splitters) filled with felt coated mineral wool attenuation material.

Connection measurements: 400 x 300 - 3000 x 3000.
Bigger attenuators are reinforced by an outer modular frame.
Connection frame possibilities: 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 (door). Fully cleanable and openable attenuators you find in the product range: MINKA-A.

Fire classification mineral wool: EN 1182: non-combustible; Fire-reaction: EN 13501: class A2.

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 perofmance.

Tested according to ISO 7235 standard.
