LDR-B 60-40 Silencer, baffle

Art. no.: 9241

Rectangular baffle silencer

Description

LDR-B is fitted with built-in baffles and side baffles located outside the fitting dimensions.

Design

LDR-B has an external shell of trapezoidal corrugated sheet for stability and reduced risk of natural oscillation. LDR-B 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. LDR-B meets the requirements of air tightness class C and pressure class 2 according to EN 1507:2006.
