  Model Pro Jet - Architectural Linear Slot Diffusers  
  • Linear diffuser system with engineered performance that integrates inconspicuously as an architectural feature of the space
  • Long throw capability, single slot appearance
  • Jet discharge pattern perpendicular to the diffuser face for both heating and cooling applications
  • High ceiling applications to project conditioned air down walls
  • Sidewall applications to project air across the space as a free jet for rapid mixing or attach to the ceiling for increased throw distances
  • Supply, return, or exhaust air through the same continuous run of architectural linear eliminates ceiling clutter and reduces installation costs
  • Drywall / hard surface and suspended ceiling applications
Product Features
  • Heavy extruded aluminum construction
  • 12’ lengths available to minimize joints
  • 1”, 1-1/2”, 2”, 2-1/2”, 3” slot widths
  • 1 thru 4 slots
  • Field adjustable nozzle varies jet velocity and throw distance
  • Nozzles are nominal 24” and consist of two sliding elements for volume control as well as blank-off for inactive sections
