  Model Free Flo - Architectural Linear Slot Diffusers  
       
 
Application
  • Linear diffuser system with engineered performance that integrates inconspicuously as an architectural feature of the space
  • Desirable large capacity, single slot appearance
  • Versatile pattern & volume control for installation in low or high sidewalls and ceilings for both heating and cooling applications
  • Adjustable for horizontal or vertically projected air discharge patterns
  • Supply, return, or exhaust air through the same continuous run of architectural linear eliminates ceiling clutter and reduces installation costs
  • Draftless air distribution excellent for VAV applications – blankets of air will not “dump” even at lowest flow rates
  • Drywall / hard surface and suspended ceiling applications
