Acoustic silencers — made in Quebec, ASTM E477
Ventilation systems carry mechanical noise straight into work areas and neighbouring spaces. Our custom silencers treat it inside the duct — straight, elbow or round, sized to your network.
Applications
Supply and return ducts that carry fan noise through the building.
Fresh-air intakes and exhaust outlets that radiate noise outdoors.
At the source, right where mechanical noise enters the network.
Process and dust-collection exhausts subject to noise thresholds.
Openings and ducts connecting mechanical rooms to occupied spaces.
Straight, elbow or round configurations to fit the layout of your network.
Why Deflection
The reference standard for evaluating the acoustic performance of duct silencers.
Galvanized steel, satin-coat (paintable to your colours) or stainless steel for corrosive environments.
Including a high-transmission-loss construction for demanding attenuation requirements.
Straight, elbow or round — chosen from your mechanical drawings.
Acoustic media films (Tedlar, Melinex, fiberglass cloth) and lifting rings available.
No standardized one-size model: each silencer is built to the dimensions and requirements of your project.
How it works
Duct dimensions, airflow and noise requirements. Response within 24-48 business hours.
Configuration, material and gauge recommended by our specialists, with acoustic study if needed.
The silencer is manufactured in Quebec to your exact dimensions.
Delivered ready to install — RBQ-certified installation available as an option.
Describe your duct network and noise requirements — a specialist replies within 24-48 business hours.
An acoustic enclosure wraps the noisy equipment; panel screens protect a perimeter.
