Reducing noise in commercial ventilation systems.
Attenuators help manage air movement noise in commercial exhaust and supply systems. Installed in-line with the ductwork, they reduce breakout noise, fan discharge noise and general system sound levels, allowing projects to meet acoustic requirements while maintaining effective airflow.
Cyclomade® attenuators are available in circular and square / rectangular configurations to suit a wide range of commercial applications, including kitchens, retail environments, mixed-use developments, education facilities, hospitals and industrial sites. Each unit is constructed with a perforated internal liner and acoustic infill to absorb sound energy, supported by a durable outer casing for long-term performance.
Selection depends on the required noise reduction, available space, system static pressure and duct configuration. Our team can assist with sizing and placement to help ensure the attenuator
Designed for round duct systems and direct connection to fan spigots where compact, efficient noise reduction is required. Suitable for commercial kitchen exhaust, general ventilation and supply air systems.
Suited to larger duct systems where greater surface area is required for noise absorption. Common in retail centres, mixed-use projects and commercial buildings with higher airflow volumes.
It reduces noise travelling through the ductwork by absorbing sound energy as air moves through the system.
Yes. All attenuators introduce a small amount of static pressure. This is considered during fan selection.
They are commonly positioned close to the fan outlet or in locations where breakout noise may affect adjacent spaces.
