    Product Application

    We have designed model AMA by combining superior design and ultimate quality to provide a solution that exceeds your expectation. It is available in 1-way, 2-way, 3-way or 4-way air patterns, allowing you to adjust it to a multitude of arrangements. It is an ideal solution for spaces that require changing air pattern, like libraries and classrooms. A distinct feature of this model is the horizontal lip featured on the deflecting louver. It generates a tight ceiling air pattern that results in excellent mixing and creates a draft-free environment for your improved comfort.
