Wind Louvers – Efficient Ventilation with Weather Defense
Vanman’s wind louvers are engineered for effective air intake and exhaust while resisting water penetration. Ideal for data centers, mechanical rooms, and ventilation shafts, these louvers ensure airflow performance while preventing rain intrusion or backflow.
Class A Rain Resistance with Space Efficiency.Achieves Class A rain resistance at 2m³/s airflow. Compact 100mm frame ideal for tight-space applications. Hollow inner blade resists hurricane debris impact.
Performance in Weatherproof and Rain Protection
Our weatherproof and waterproof aluminum louvers are optimized for rain rejection while maintaining airflow efficiency. Rated for BSRIA or AMCA performance, these louvers excel in high-exposure zones like rooftop screens and air handling units.
Double Bank Systems for Enhanced Rain Resistance
Vanman’s double bank aluminium louver panels are the preferred solution for rain penetration control. These louvers feature horizontal blade configurations with aerodynamic profiles and are suitable for rain-intense environments.
Decorative Appearance with Balanced Performance.Wide-blade spacing enhances appearance while maintaining airflow. Inner and outer blades ≥1.5mm thick. Effective for architectural ventilation needs.
Applications: Air Performance & Industrial Use
Designed for mechanical rooms, cooling towers, or large enclosures, our louvers support high airflow and directional control. Options include air performance louvers, equipment screen louvers, and box louvers for tailored project needs.
FAQ
Q: What is the function of wind-driven rain louvers?
A: Wind-driven rain louvers are designed to block water ingress during strong wind and rain events while allowing airflow. They are ideal for building envelopes and mechanical systems.
Q: What is a double bank aluminium louver?
A: Double bank louvers feature two blade paths that deflect water, ideal for performance-critical ventilation zones and air intakes.
Q: Are Vanman's louvers AMCA or BSRIA certified?
A: Yes. Many of our louvers are performance tested to meet AMCA 500-L or BSRIA standards for airflow and rain resistance.
