DLD has a conventional design with dimensions that not exceed the corresponding connection dimensions. The silencer can be manufactured in all standard duct sizes.
For low-built solutions, see LRLB page .
DLD has an outer sheet casing of trapezoidal corrugated sheet metal for stability and reduced risk of natural oscillation.DLD is designed for low air resistance with baffle combinations that attenuate particularly low-frequency noise well.The type of insulation material has been developed to provide good noise properties, low weight and to be cleanable.
DLD meets the requirements of air tightness class C.
Tools for dimensioning and planning
The software CADvent and DIMsilencer offer features for dimensioning and selection of products in an environment with 3D modelling. Computerised planning can be conducted with automatic presentation of noise levels, pressure drop etc.
