Cylindrical Sound Attenuator
- Nominal Diameter: 200mm to 1250 mm
- Insulation Thickness: 50mm or 100mm
Product Overview
The ICEMAC Cylindrical Sound Attenuator is designed to reduce noise in HVAC and ventilation systems while maintaining efficient airflow. It is ideal for fan installations, ducted air systems, and industrial applications where noise control is critical.
Built with a galvanized steel outer casing and a perforated sheet metal inner surface (Ø5 mm), it ensures durability, corrosion resistance, and optimal noise absorption. The insulation layer consists of high-density rock wool (50-100 mm thickness, 50 kg/m³), certified to DIN 4102 (A2 Class) for fire safety and soundproofing.
Available in three models:
IC-CS-A (Duct Type) – For inline duct applications, ensuring smooth airflow and effective noise reduction.
IC-CS-B (Fan Type) – Designed for fan integration, minimizing noise at air intake and discharge points.
IC-CS-C (With Pod) – Offers enhanced acoustic performance, ideal for highly noise-sensitive environments.
With its compact and efficient design, this attenuator integrates seamlessly into modern HVAC systems, ensuring effective noise control and energy efficiency.
Key Features
Superior Noise Absorption – Perforated sheet metal (Ø5 mm) and high-density rock wool (50-100 mm) reduce sound transmission.
Durable & Fire-Resistant – Galvanized steel outer casing and fire-rated rock wool (DIN 4102, A2 Class) ensure long-term reliability.
Optimized Airflow Efficiency – Designed to maintain smooth air circulation while reducing noise.
Versatile Configuration Options – Available in IC-CS-A (duct type), IC-CS-B (fan type), and IC-CS-C (pod version) for different applications.
Customizable Finishing – Standard electrostatic powder coating in RAL 9010 & RAL 9016, with custom colors available upon request.
Secure & Flexible Installation – Screw-mounted for duct integration or bolt-assembled for fan connection, ensuring stability.
