Systemair LDC Ventilation Noise Attenuator

The LDC muffler easily mounts to round air ducts. Equipped with connection flanges that facilitate assembly work. LDC effectively reduces sound levels in air ducts. In cases where the sound reduction requirements are very high, it is very effective to install two silencers - one after the other. For the most effective sound reduction, mufflers should be installed immediately after the fan or bend.
In cases where it is necessary to ensure high requirements regarding the noise level not only in the air ducts, but also for the entire equipment in general, it is recommended to install silencers together with soundproof fans.
