The LS-A Linear slot diffuser are designed for ceiling mounting and are recommended for supplying heating, ventilation, or cooling air and returning or exhausting room air. Air pattern orientation changes through 180° are affected by integral air deflection vanes, allowing pattern adjustments to meet changing requirements.

When mounted on the ceiling, the LS-A Linear Slot Diffuser provides a horizontal air path, adjustable 180° in each slot opening. One to ten slots can be adjusted to provide one-way or two-way air patterns by directing the air-deflecting vanes to either side as needed. The vertical downward air pattern can be adjusted from all slots. Combining horizontal and vertical down patterns can be achieved with two (or more) slot linear slot diffusers.
