The Ventex 2590 is an extruded aluminum, stationary five inch (127 mm) deep, wind-driven rain louver. The advanced design utilizes centrifugal forces to capture water droplets as the air passes over the sightproof drainable blades, maximizing weather protection even at higher airflow velocities. The design of the 2590 will improve the weather tightness of the building envelope, while maintaining efficient air flow performance required by the ventilation system. Model 2590 is AMCA Certified for Wind-Driven Rain and Air Performance.
