Specification:
Rectangular Sound Attenuators made of high quality 1 mm thick Galvanized Sheet with 100 to 200 mm thick baffles consisting of 48 Kg/m3 density rockwool lined with RP tissue and perforated sheets and 150 to 200 mm air way gap as standard with V shaped entry and exit. Different specifications can be made to customer requirements based of sound attenuation requirements.
Our Rectangle Sound Attenuators are high-performance acoustic solutions designed to reduce noise levels in HVAC duct systems while maintaining efficient airflow. As a trusted Rectangle Sound Attenuator manufacturer in India, we supply premium quality duct silencers that ensure maximum noise reduction, minimal pressure drop, and long-lasting durability for commercial and industrial applications across India.
Engineered with advanced acoustic design principles, the Rectangular Sound Attenuator in India provides effective noise attenuation without compromising system performance. It is widely used in environments where controlling HVAC noise is critical for comfort and compliance.
The HVAC Sound Attenuator is aerodynamically designed to achieve maximum insertion loss while maintaining low pressure drop. The air gap and silencer length are carefully selected to meet the required Noise Criteria (NC) levels, ensuring optimal acoustic performance.
This makes the Rectangle Sound Attenuator in India ideal for applications where both airflow efficiency and noise reduction are essential.
The Rectangular Duct Silencer features splitters with V-shaped entry and exit profiles, which help minimize turbulence and reduce self-generated noise. The combination of full-width central splitters and half-width side splitters ensures effective sound absorption across the duct.
This advanced design enhances acoustic performance while maintaining smooth airflow within the HVAC system.
Our Rectangle Sound Attenuator in India is built with a robust casing using lock-formed seams that meet SMACNA standards, ensuring excellent strength and rigidity. The entire unit is thoroughly sealed to prevent air leakage, improving system efficiency.
The duct mate flange connections on both ends, compliant with DW144 standards, allow secure and easy installation within duct systems.
The Acoustic Sound Attenuator is filled with high-quality acoustic media that is:
Non-combustible
Fungi-resistant
Biologically inert
The insulation meets international standards such as EN ISO 1182 and ASTM C665, ensuring safety and durability. The material offers excellent noise reduction coefficient (NRC) performance, making it highly effective for sound attenuation.
A single-faced liner with perforated metal is provided to prevent the acoustic media from entering the air stream, ensuring clean and safe airflow.
Optional fiberglass insulation is also available for enhanced acoustic performance.
The Rectangle Sound Attenuator in India is tested and certified by Intertek USA (NVLAP accredited laboratories) in accordance with ASTM E477-06a standards, ensuring reliable acoustic and airflow performance.
This certification guarantees that the product meets international quality and performance benchmarks.
The Rectangular Sound Attenuator is available in multiple air gap sizes to suit different noise control requirements:
50 mm
75 mm
100 mm
125 mm
150 mm
175 mm
200 mm
250 mm
This flexibility allows HVAC designers to select the appropriate configuration for specific applications across India.
Our Rectangle Sound Attenuators are widely used in HVAC systems across India, including:
Commercial office buildings
Hospitals and healthcare facilities
Industrial plants and factories
Auditoriums and theatres
Hotels and hospitality projects
Airports and infrastructure developments
Data centers and server rooms
These environments require effective noise control solutions to maintain comfort and compliance.
