Plenum Slot Diffusers

Plenum slot diffusers are an integral part of the variable air volume system. They blend in with ceiling architecture while providing extraordinary air distribution qualities. These diffusers also reduce the effect of down draft at low air volumes and discharge a remarkable uniform airflow. Models are available for supply, return, and supply/return combination.
