MORENDO

The MORENDO is a rectangular sound attenuator with extra low installation height to enable it to be used in installations where available space is restricted.

The MORENDO is made as standard of galvanized sheet steel to Corrosivity class C3 (VVS-AMA 2019 Standard).

The sound-attenuating material, ISOVER Cleantec^® PLUS, is a type-approved insulation material consisting of long-fibred, compressed mineral wool which is covered with a special micro-perforated foil. ISOVER Cleantec^® PLUS is type-approved with regard to cleaning, fibre entrainment, resistance to ageing, emissions, washable surfaces etc., to type-approval number 2706/92.

The standard MORENDO is supplied with slip clamp connections.

The MORENDO is available in an insulated version with 50 mm thick fire-resistant stone wool. In this version, all the insulating surfaces are covered with perforated sheet steel, MORENDO T3.

If the air is severely polluted with particles or if for some other reason a more robust design is required, the acoustic baffles can be covered with perforated sheet steel over the ISOVER Cleantec® PLUS insulation, MORENDO T4.

MORENDO is perfectly suited to reduce sound from dampers in the duct system as well as to be installed directly by the ventilation unit.

The slip clamps on this product are designed for connection to ducts only. The product should be suspended with support under its entire width.
