TRUaire SU1A-S Universal Spiral Diffusers With Scoop Aluminum Finish

Spiral SU1A-S Universal Duct Diffusers were born of the rustic exposed ceiling era in architectural design. Wherever air needs to leave ductwork and enter the conditioned space a hole is cut in the duct. A register is then attached for directional air control and aesthetics. These universal diffusers do not includes a matched duct saddle but instead seal to the duct using the included thick gasket.

  • Unfinished aluminum appearance
  • Single deflection configuration
  • Includes adjustable air scoop
  • No damper 
  • No saddle. Includes thick sealing gasket
  • Adjustable bars on grille face

Note that LIST SIZE is the size of the duct opening.  MINIMUM DUCT SIZE IS REQUIRED FOR SEALING.  SEE SUBMITTAL SHEET OR SPECS TAB FOR MIN DUCT SIZE INFO AND ACTUAL GRILLE DIMENSIONS.
