Special versions
The product can be ordered in special versions:
• Flanged connection instead of slide rail connection.
• Internal and external epoxy coating.
• Stainless steel construction.
• Contact our sales if aluzinc-coated steel sheet is required.
• Outer casing, splitters (baffles) and guide rails made of unpainted galvanized steel sheet.
• Insulation made of washable, sound-absorbing, non-combustible mineral wool, surface-coated with perforated sheet metal.
• The product is designed for installation in rectangular ducts and is supplied with a slide rail connection.
• The product can also be supplied with a flanged connection (specified when ordering) and is then mounted to a mating flange using bolts and nuts.
• To meet airtightness class C requirements, the attenuator must be installed according to specific guidelines, usually the installation instructions provided by the duct system manufacturer.
• The product must not be mounted solely suspended at the connection points.
• During installation, suspension supports that wrap around the outer casing must be used.
• Provide a minimum straight duct length of 4 × ØD upstream of the attenuator to ensure the stated acoustic performance.
• See the operation and maintenance documents*) for more information on installing the product.
