High performance adjustable variation of our patented drainable blade configuration in 4'' thickness. The adjustable feature is useful on systems requiring periodic operation: in the open position the louver functions conventionally, while in the closed position the louver provides a tight shutoff. The A-DBE-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.
