Linear Slot Diffusers manufactured by JMC have been designed to satisfy architectural concepts that require continuous length applications without compromising air distribution performance.

These diffusers utilizes an adjustable vane in each slot to control the direction of air discharge either parallel with or perpendicular to its face surface.


The adjustment from the face of the diffuser allows for pattern control in a full 180 degree range for either right or left parallel, intermediate or perpendicular.
