Attenuators

Attenuators & Duct Silencers

Fresh Air Supplies supplies circular silencer attenuators engineered to reduce airborne noise generated by fans, air handling units, and mechanical ventilation systems. Noise control is an increasingly important consideration in both commercial and residential ventilation design, and a correctly specified attenuator can make the difference between a compliant installation and a costly remediation job.

Our attenuators are built for reliable in-duct performance and are suitable for integration into a wide range of circular duct systems.

When selecting an attenuator for a ventilation system, the key variables are duct diameter, required insertion loss, and available pressure drop budget. Oversizing or undersizing an attenuator affects both acoustic performance and system efficiency.

Our team has extensive experience helping engineers, contractors, and specifiers select the right silencer attenuator for the job. Contact our sales team on 028 8675 2336 for technical support, or browse our attenuator range online and order for fast UK and Ireland delivery.
