Effective noise suppression

The LDR rectangular baffle silencer effectively suppresses noise transmitted to the duct.

Universal flange

The LDR rectangular baffle silencer is supplied with a universal flange that is suitable for both the PG flange and Metu profile.

Low air resistance

LDR is designed for low air resistance with baffle combinations that effectively dampens low-frequency noise.

The LDR is a baffle silencer with a rectangular design. It is designed for easy fitting immediately before or after components in rectangular ducts. It provides effective suppression of noise transmitted to the duct. LDR is designed for low air resistance with baffle combinations that dampen particularly low-frequency noise well. The silencer should be used together with an insulated fan where there is a requirement for noise suppression both in the duct and in the surroundings as a whole.

All silencers are supplied with a universal flange suitable for PG flange or Metu profile fitting. LDR is fitted with built-in baffles and side baffles located outside the fitting dimensions. It has an external shell of trapezoidal corrugated sheet for stability and reduced risk of natural oscillation. It features Lindtec as an insulation material that has been developed to provide good noise properties, low weight and to be cleanable.
