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.  See submittal sheet for actual grille dimensions.
