Aluminum Weatherproof Louvre

The Aluminum Weatherproof Louvre is a high-performance external ventilation protection component designed for HVAC air intake and exhaust systems installed on building façades. It is engineered to provide reliable weather resistance while maintaining efficient airflow performance in outdoor ventilation applications.

All units are manufactured on a project-based, made-to-order system according to façade dimensions, airflow requirements, and architectural design specifications. No standard stock sizes are available.

Engineering Design Concept

This weatherproof louvre features an inclined blade aerodynamic structure designed to block rainwater penetration while allowing continuous air movement through the ventilation system.

It is widely used as an external air terminal in HVAC systems where both weather protection and stable ventilation performance are required.

Rain Protection & Airflow Performance

The inclined blade structure provides:

• Effective rainwater resistance and wind-driven water prevention
• Continuous and stable airflow for HVAC intake and exhaust systems
• Reduced risk of water ingress in façade ventilation openings
• Stable performance under outdoor wind pressure conditions
• Suitable for both air intake and exhaust applications

Problems This Product Solves

• Rainwater entering HVAC ventilation ducts
• Wind-driven water penetration in façade openings
• Poor protection of external air intake systems
• Reduced efficiency due to outdoor environmental exposure
• Lack of durable external ventilation protection in HVAC systems

Material & Construction

• Material: High-strength extruded aluminum alloy
• Structure: Corrosion-resistant for long-term outdoor use
• Surface finish: Electrostatic powder coating
• Standard color: RAL matte white (custom RAL colors available)
• Designed for long-term exterior architectural applications

Custom Manufacturing Capability
