The K-JETA air nozzles are designed to be architecturally attractive when installed along a perimeter wall in overhead ceiling tiles. The nozzles are provided with a retaining ring, which is pushed on to the rear collar to secure the nozzle to the ceiling tile. The nozzles provide a vertical jet of air that is effective in both heating and cooling applications. The K-JETA also has the ability of 60° directional adjustment of the vertical air column by rotation of the center concentric rings making this unit the ideal choice for installation near windows.
