ODA-400 [a]
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 an 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.
• This prouduct is discontinued and has been replaced by ODA [b], version b.
Delivery form
• The product is delivered in pairs, including mounting frame RAM-ODA [a].
• The unit is delivered in one size and is adapted by means of the cut-out diameter of the air opening in the wall (Ø100/125/160 mm).

– Available for two different wall depths (70 mm alt. 95 mm).
– A total of 6 different application scenarios.
Wall depth | Hole cutting (Ø) | Designation
70 mm | Ø100 / Ø125 | OFI-C70-100-125
95 mm | Ø100 / Ø125 | OFI-C95-100-125

95 mm | Ø160 | OFI-C95-160
• ODA/ÖDA [a]: The product is made of aluminium, powder-coated in white RAL standard color, internally insulated with washable and surface-coated sound absorber. The product's insulation consists of 100% recycled, non-allergenic, hydrophobic PET plastic material. It is free from formaldehyde and, when burned, only carbon dioxide and water are produced.
• RAM-ODA/ÖDA [a]: Mounting frame, made of hot-dip galvanized sheet steel.
• OFI-C: Made from environmentally friendly, flame-retardant polyurethane foam. The material is CertiPUR and Oeko-Tex certified.
• The product is installed in pairs with mounting frame RAM-ÖDA [a] on either side of the wall over circular holecuttings, frame parts secured with screws.
• The mounting frame is supplied in one size and is used for installation for all three hole cutting dimensions, Ø100, Ø125, and Ø160 mm.
• When fibre protection sleeve OFI-C / ÖFI-C is used, the protection sleeve must be fitted into the hole cutting before mounting the transfer unit.
• The fibre protection cover can be installed either before or after installation. The sleeve penetration's elastic and self-tensioning properties make it easy to press into the hole in the stud wall.
• The diffuser is hooked onto the mounting frame at the top and then pressed into place at the bottom.
• The mounting frame functions as a sliding rail, enabling some horizontal adjustment of the diffuser front.
