Exposed building openings—such as mechanical rooms, parking garages, and exterior walls—require ventilation to prevent moisture buildup and overheating, but often suffer from water infiltration during heavy rain or storms. These specialized louvers solve this with a pressure-equalized design and marine-grade materials, achieving 99% water exclusion while maintaining optimal airflow. Engineered for commercial and industrial construction, they protect interior spaces from water damage while reducing energy costs associated with mechanical ventilation.
Advanced Water Resistance: Multi-stage defense system includes sloped blades (15° pitch), EPDM gaskets, and drainage channels that achieve IP54 ingress protection—withstanding rainfall intensities up to 150mm/h (ASTM E331) without water penetration.
Corrosion Protection: 6063-T5 aluminum profiles undergo chromate conversion + PVDF coating, delivering 2000 hours of salt spray resistance (ASTM B117)—suitable for coastal, industrial, and high-humidity environments.
Optimized Airflow: Aerodynamic blade design minimizes pressure drop while maximizing ventilation, allowing 400-600 m³/h per m² airflow to cool mechanical equipment and reduce condensation in enclosed spaces.
Structural Integrity: 2.0mm thick aluminum frames with reinforced corners resist wind loads up to 6kPa (equivalent to category 1 hurricane winds), maintaining performance in extreme weather events.
Mechanical Rooms: Protect HVAC equipment, electrical panels, and generators from rain while providing necessary airflow to prevent overheating and moisture buildup.
Parking Garages: Reduce humidity and exhaust fumes in enclosed parking structures with waterproof louvers that prevent rainwater infiltration during open-air ventilation.
Industrial Facilities: Chemical plants and manufacturing sites utilize the corrosion-resistant design to ventilate hazardous areas without exposing interior components to water or chemical spray.
Coastal Buildings: Beachfront hotels and residences benefit from the saltwater resistance, maintaining ventilation and protection in environments where standard aluminum quickly degrades.
Q: How do these louvers prevent water infiltration during wind-driven rain?
A: The pressure-equalized design creates an air barrier that neutralizes wind pressure differentials, while overlapping blades and labyrinth seals direct water outward through dedicated drainage channels—even during 110km/h winds.
Q: Can they be installed on curved or irregular facades?
A: Yes, modular components allow installation on radius walls and complex geometries, with custom sizing available for non-standard openings. Our technical team provides layout drawings for complex installations.
Q: What maintenance is required in industrial environments?
A: Quarterly cleaning with mild detergent removes dust and debris; annual inspection of gaskets ensures continued water resistance. In industrial zones with heavy particulate matter, we recommend semi-annual pressure washing.
Q: Are they compatible with insect screens?
A: Yes, optional stainless steel insect screens (20x20 mesh) can be integrated without compromising water resistance or airflow, preventing pest access to mechanical spaces.
