Intake louvers are designed to protect air intake and exhaust openings in exterior walls. Applying the same principles of unobstructed airflow, precipitation blocking and moisture control as traditional door louvers, intake louvers offer high levels of air intake often required in commercial and industrial environments such as warehouses, retail and office spaces, and hospitals. Choose from air intake, drainable, wall and ventilation louvers depending on your needs. Specify the width, height and finish you want before purchase.
