The adjustable design variant of our step blade configuration louver, the A-LEG-04 utilizes a shallow 20-degree blade angle with a rear step designed to maximize free area and minimize pressure drop when in the open position while providing tight shutoff when closed, ideal for systems requiring periodic operation or an extra degree of weather protection.  The A-LEG-04 comes with either a manual operator or a 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.
