Rectangular Sound Attenuator
- Length- 800 mm to 2000 mm
- Baffle Thickness: 100mm or 200mm
Product Overview
The ICEMAC Rectangular Sound Attenuator is designed to minimize noise transmission in HVAC systems, air ducts, and ventilation units while ensuring smooth airflow. It is ideal for commercial buildings, industrial facilities, hospitals, and offices, providing a quiet and comfortable environment.
Manufactured from high-quality galvanized steel (0.6 mm – 1.5 mm thick), it offers durability, corrosion resistance, and long-lasting performance. The internal splitters (0.6 mm – 1.0 mm thick) are insulated with high-density rock wool (50 kg/m³), certified to DIN 4102 (A2 Class) for fire safety, and lined with fiberglass to prevent particle release in high airflow conditions.
Available in two models for different noise reduction needs:
200 mm Splitter Model – Maximum sound attenuation, suitable for noise-sensitive environments such as hospitals, schools, and offices.
100 mm Splitter Model – Standard noise control, widely used in commercial and residential HVAC systems.
This sound attenuator ensures effective noise control, energy efficiency, and seamless integration into HVAC ductwork and ventilation systems.
Key Features
High-Performance Noise Reduction – Galvanized steel splitters (100 mm or 200 mm) and rock wool insulation (50 kg/m³) ensure optimal sound absorption.
Durable & Fire-Resistant Build – Casing (0.6 mm – 1.5 mm thick), splitters (0.6 mm – 1.0 mm thick), and rock wool insulation comply with DIN 4102 (A2 Class) fire safety standards.
Optimized Airflow Efficiency – Maintains ventilation performance while reducing sound transmission.
Customizable Sizes & Configurations – Baffle thickness available in 100 mm or 200 mm, with adjustable width and height for different duct systems.
RAL Color Coating Available – Customizable surface finishing upon request for seamless HVAC integration.
Easy Installation – Screw mounting or bolt and clip assembly ensures secure and stable attachment to duct systems.
