Specification:
Circular Sound Attenuators made of high quality 1 mm thick Galvanized Sheet with baffles consisting of 48 Kg/m3 density rockwool. Different specifications can be made to customer requirements based of sound attenuation requirements.
Our Circular Sound Attenuators are high-performance acoustic solutions designed to reduce noise levels in round duct HVAC systems while maintaining efficient airflow. As a trusted Circular Sound Attenuator manufacturer in India, we supply premium quality round duct silencers that provide superior noise reduction, minimal pressure drop, and long-lasting performance for commercial and industrial applications across India.
Engineered with advanced aerodynamic and acoustic principles, the Circular Sound Attenuator in India ensures optimal sound attenuation without compromising airflow efficiency. Its circular design eliminates the need for square-to-round transitions, reducing pressure losses and improving system performance.
The Round Duct Sound Attenuator is specifically designed to achieve maximum insertion loss while maintaining low pressure drop, even at high air velocities. The circular construction allows smooth airflow, reducing turbulence and enhancing system efficiency.
The Circular Sound Attenuator in India is ideal for HVAC systems where both noise control and airflow performance are critical.
The Circular Acoustic Attenuator features a centre splitter (pod) that is radiused at both ends to minimize self-generated noise and pressure loss. This design ensures smooth airflow while maximizing sound absorption.
The attenuator also includes full-width central splitters and half-width side splitters along the circumference, providing effective noise reduction across the entire airflow path.
This advanced splitter configuration enhances acoustic performance and ensures consistent noise attenuation.
Our Circular Sound Attenuator in India is constructed using high-quality materials with lock-formed seams that meet SMACNA standards, ensuring excellent strength and structural rigidity. The casing is thoroughly sealed to prevent air leakage, improving overall HVAC system efficiency.
The unit is designed for long-term, maintenance-free operation, making it suitable for continuous use in demanding environments.
The Circular Sound Attenuator is filled with premium acoustic infill media that is:
Non-combustible
Fungi-resistant
Biologically inert
The insulation material complies with EN ISO 1182 and ASTM C665 standards, ensuring safety and durability. It provides excellent noise reduction coefficient (NRC) characteristics, making it highly effective in reducing HVAC noise.
The design ensures that the acoustic media remains secure and does not enter the air stream, maintaining clean and safe airflow.
The Circular Sound Attenuator in India is designed with slip connections on both ends, compliant with DW144 standards, allowing easy and secure installation into round duct systems.
This simplifies installation and ensures proper alignment within HVAC duct networks.
The Round Duct Silencer is capable of handling high air velocities without significant pressure drop. This makes it suitable for large-scale HVAC systems where efficient airflow and noise control are essential.
Our Circular Sound Attenuators are widely used in HVAC installations across India, including:
Commercial office buildings
Industrial plants and factories
Hospitals and healthcare facilities
Hotels and hospitality projects
Airports and transportation hubs
Data centers and server rooms
Auditoriums and theatres
These environments require effective noise control solutions to maintain comfort and compliance.
To meet diverse HVAC requirements, we offer custom sizes for Circular Sound Attenuators in India. This ensures seamless integration with round duct systems and specific project needs.
