L300A
Acoustic ventilation louvre for plant noise control applications. 300mm deep unit providing enhanced noise attenuation with a balanced free area for effective airflow.
Application
- Plant enclosures and rooftop plant areas requiring noise attenuation and ventilation
- Air intake and discharge points where control of plant noise breakout is required
- Building façades incorporating acoustic ventilation for environmental noise control
- Service yards and back-of-house areas with noise-sensitive boundaries
- Data centres, energy centres, substations and infrastructure buildings
- Developments requiring compliance with planning conditions relating to plant noise
- Commercial and industrial buildings where acoustic performance and airflow are both critical
Description
SoundEX L300 is an acoustic ventilation louvre designed to provide effective noise attenuation in applications requiring airflow, including plant enclosures, rooftop plant areas, and service zones.
The 300mm deep louvre construction delivers enhanced acoustic performance compared to shallower systems, while maintaining a balanced free area for effective ventilation. This makes it well suited to projects where both noise control and airflow are key design considerations.
Louvre blades are set at a 200mm vertical pitch and inclined at 45°, incorporating a non-combustible acoustic infill to reduce noise transmission through the unit. A mesh lining is applied to the underside of the blades to retain the acoustic media and ensure long-term durability.
Tested acoustic performance data, including insertion loss across octave band frequencies, is available, with systems independently tested by the University of Salford.
The system can be manufactured from aluminium, galvanised steel, or stainless steel, and is available in a wide range of finishes to suit architectural and environmental requirements.
All SoundEX systems are available as factory-assembled modules or in kit form for in-situ assembly, providing flexibility to suit site constraints, access limitations, and installation preferences.
