  Model SLSD - Steel Linear Slot Diffuser  
       
 
Application
  • Steel linear plenum-slot diffuser with 1 or 2 way discharge air pattern, 1 to 4 slots provide great flexibility for desired throw distances
  • Fixed air pattern / deflection
  • Matching return units for ducted or plenum return systems
  • Draftless air distribution excellent for VAV applications – blanket of air will not “dump” even at lowest flow rates
  • Integrates with inverted T-bar or 9/16” narrow slot grid systems with “straddle” or “cross-notch” arrangements.
Product Features
  • Heavy gauge, all steel, coated construction (extruded surface frame used for hard ceilings)
  • No visible mounting fasteners at diffuser face.
  • Integral supply air plenum minimizes air leakage.
  • Plenum inlet located on either side for ease of
    installation
  • All 2 way models include notched end caps to straddle the grid.
  • End caps are recessed to keep diffuser and tiles flush and in the same plane.
  • Designed for 1” inverted T-bar or 9/16” narrow slot grid systems. Available for surface mounting in hard ceilings with a surface frame.
  • White finish on exposed surfaces sets the industry standard for preferred neutral colors and gloss, with exceptional durability
  • 2’,3’,4’,5’ nominal lengths & round inlets for easy duct connections and lowest sound and pressure levels.
  • Diffuser lip supports adjacent ceiling tiles – no additional Tees are required.
Options
  • Cross-notch on 48” units, for 2’x2’ grid systems.
  • 1/2” internal glass fiber insulation. External insulation, and “fiberless” insulating systems available.
  • Round volume damper in inlet.
  • Special lengths
  • Custom paint colors
