Rainproof & Silencing Louver
Endless Exploration, Boundless Opportunities
Acoustic louver FTACL‐101
-
In densely built areas, noise generated by machinery or other sources (such as underground parking) needs to be suppressed to meet regulatory requirements. Usually, the best way for noise to enter the surrounding area is through ventilation ducts.
The noise reduction shutters can effectively reduce the noise transmission without hindering the operation of the ventilation system.
Features:
• Reduce the noise of the generator inlet and outlet; reduce the noise of the exhaust of factories and buildings• Frame material: 6063-T5 extruded aluminum, nominal wall thickness 3mm
• Blade: 6063-T5 extruded aluminum, nominal wall thickness 1.5mm
• Sound-absorbing material: glass fiber, rock wool, silent cotton
• Connecting rod (optional): welding, riveting
Industry Standards
In the fields of air handling, ventilation, noise control, safety protection, and air filtration within building and industrial environments, the following professional standards are typically applied:
- EN 13030: Louver/vent valve aerodynamic performance testing, applicable for flow rate coefficient, pressure drop, and rain resistance. It is used to evaluate the aerodynamic performance of noise-reducing louvers in ventilation conditions.
- AMCA 500-L: Vent valve/louver housing testing methods, applicable for air leakage, pressure drop, and water tightness. It supports testing and certification of product aerodynamic performance and sealing performance.
- AMCA 511: Certification and labeling program, applicable for AMCA certification catalog and requirements. It enhances third-party certification of product performance and market recognition.
- ISO 10140: Acoustics performance testing for building components, applicable for sound insulation and sound transmission loss. It is used to evaluate the acoustic noise reduction effect of noise-reducing louvers.
- EN 1627: Security classification for building openings, applicable for security and break-in resistance. It is applied to ventilation louvers and other components with security requirements.
- EN 779: Air filter classification and efficiency, applicable for particle filtration efficiency evaluation methods, used for controlling particulate matter and assessing air quality in ventilation systems.
