  Model SPT - Punkah Style Spot Diffuser  
  • Punkah type spot diffuser provides architecturally preferred high end appearance
  • Ideally suited for predictable directional control of conditioned air within large spaces such as malls, exhibit halls, sports arenas, industrial and manufacturing facilities, atrium areas, and large office building entrances.
  • Small nozzle sizes provide shorter throws for smaller spaces
  • Spot air distribution ideal for industrial heating, ventilating, or cooling
  • Side wall, ceiling, or duct mounted applications – any orientation
  • Rapid temperature equalization eliminates stratification
