A ball louver assembly for controlling the direction of pressurized air passing through the openings of a ball shaped louver. The ball louver mechanism comprises a ball louver liner, which holds the ball louver and liner inside and between front and rear retainer rings. An inner ring attached to the back edge of the front retainer ring allows the ball louver with its attached liner to be turned in any rotational direction to direct the forced air as desired. The structure of the ball louver and the liner allows the ball louver to be turned into a position to close, reduce or select the direction of the pressurized air leaving the air conditioner through the openings in the ball louver body. This structure is similar to basic gyroscope axis principles in its mobility of the ball louver in any direction by incorporating a new liner with or without spring-like compression effects and/or with or without notch-bump presence to help hold the ball louver in the last desired position without vibration or forced air being able to cause movement of the ball louver from its last desired set position. Another feature in the liner gives compression spring-like increased coefficient of friction to the axle of the rotational ball louver to hold in the desired set position.
