The adjustable variant of our classic straight bladed louver, Model A-LEC-04 is a louver that combines form and function, adding both aesthetic appeal and reliable performance to any building. The adjustable feature is useful on systems requiring periodic operation: in the open position the louver functions conventionally for intake or exhaust, while in the closed position the louver provides a tight shutoff. The A-LEC-04 comes with either a manual operator or factory-mounted and calibrated electric actuator. Syncing the electric actuator with intake or exhaust fan operation with auxiliary switches allows for positive control of ventilation while minimizing water and outside element penetration.
