DLDY is fitted with built-in side baffles located outside the fitting dimensions. The products can be manufactured in all standard duct sizes.
DLDY has an external shell of trapezoidal corrugated sheet for stability and reduced risk of natural oscillation.
DLDY is designed for low air resistance with baffle combinations that dampen particularly low-frequency noise well.
The type of insulation material is Lindtec which has been developed to provide good noise properties, low weight and to be cleanable.
DLDY meets the requirements of air tightness class C and pressure class 2 according to EN 1507:2006.
DLDY is equipped with joining profile type RJFP.
Tools for dimensioning and planning
The software lindQST, DIMsilencer and Cadvent 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.
Tested according to ISO 7235 standard.
