Main features

• Transfer air unit with optimised sound attenuation

• Environmentally friendly insulation with good attenuation properties

• Easy installation and disassembly

• Retains the same external dimensions regardless of capacity Ø100/125/160

Description

• ODA (ÖDA) is a passive transfer air diffuser for optimized sound attenuation, e.g., in situations where high requirements for sound insulation apply.

• The product and mounting frame are supplied in a one-size-fits-all configuration, using the same unit size for three circular diameters (Ø100/125/160). Adaptation is achieved through the cut-out diameter in the wall.

• For insulated stud walls, the accessory OFI-C (ÖFI-C) is recommended, an elastic wall penetration sleeve for transfer air units that prevents the spread of insulation fibres in air flows. Unlike conventional sheet metal wall penetrations installed for the same purpose, OFI-C does not impair the sound properties of the diffuser.
