Duct silencers / sound attenuators form essential components in modern HVAC systems, controlling noise while maintaining optimal airflow performance. Greenoz Cooling System Pvt. Ltd. manufactures premium acoustic solutions delivering effective noise reduction for commercial buildings, office complexes, hospitals industrial facilities, and large-scale ventilation projects across India.Â
Sound attenuators, also known as duct silencers or acoustic attenuators, manage noise generated by air movement, fans, and mechanical components in ventilation systems. These devices reduce noise levels while allowing unrestricted airflow, creating quieter indoor environments that is essential for the occupant comfort.
Our duct silencers use aerodynamic acoustic baffles filled with sound-absorbing, acoustic-grade materials. This design provides effective sound attenuation while maintaining system efficiency and minimizing pressure loss across the unit.
Rectangular duct silencers suit various HVAC applications where standard rectangular ductwork exists. These units integrate seamlessly with existing systems while providing effective noise control for office buildings, shopping centers, and commercial facilities.Â
Circular duct silencers work effectively in applications where space limitations exist, or non-standard duct sizes require acoustic treatment. Â
Custom duct silencers address specific requirements and applications ensuring optimal noise reduction and performance. Our engineering team develops specialized solutions meeting unique acoustic, dimensional, or environmental requirements for challenging projects.Â
Shopping malls, office complexes, and retail centers benefit from reduced HVAC noise improving occupant comfort and creating pleasant environments for customers and workers.Â
Hospitals and medical centers demand quiet environments for patient comfort and medical equipment operation, making sound attenuators essential for HVAC system integration.Â
Cooling towers, chillers, and DG rooms require specialized acoustic treatment managing equipment noise while maintaining operational access and performance requirements.Â
Manufacturing plants, processing facilities, and warehouses require effective noise control for worker safety and comfort while maintaining ventilation performance for equipment and personnel.Â
Greenoz Cooling System brings extensive HVAC industry experience manufacturing duct silencers and sound attenuators meeting demanding commercial and industrial specifications. Our quality-focused approach ensures reliable acoustic performance throughout operational life.Â

Rectangular duct silencers suit standard HVAC applications with rectangular ductwork, providing effective noise control for typical commercial installations. Circular silencers work best in space-limited applications or where non-standard duct sizes exist, offering comparable performance in more compact configurations.Â
Quality sound attenuators use radius inlets and tapered outlets minimizing pressure loss while maximizing noise reduction. Properly designed units typically add minimal pressure drop to systems, with aerodynamic baffles ensuring airflow efficiency isn’t compromised during acoustic treatment.Â
Noise reduction depends on silencer length, acoustic material quality, and installation configuration. Typical installations achieve 10-25 dB noise reduction across frequency ranges, with custom designs providing higher attenuation levels for specific acoustic requirements and challenging environments.Â
Greenoz manufactures custom duct silencers matching specific dimensional, acoustic, and environmental requirements. Our engineering team develops specialized solutions for challenging applications including high-temperature environments, corrosive conditions, and unique space constraints requiring non-standard configurations.Â
AHU sound attenuators reduce noise transmission from air handling equipment to occupied spaces, creating quieter environments essential for office productivity, patient comfort in healthcare facilities, and customer satisfaction in retail environments without affecting HVAC performance.Â
Sound attenuators require minimal maintenance including periodic inspection for acoustic material condition, cleaning of louver surfaces, and checking for structural integrity. Modular design allows easy access for maintenance without system shutdown, reducing operational disruption and maintenance costs.Â
