The FlowLine™ FLV Series continuous slot diffuser is designed for both ceiling and high sidewall applications and provides total air pattern control flexibility.

Similar in appearance to the FLH Series, the FLV Series features adjustable pattern controllers that direct the airstream perpendicular to the face, providing a strong vertical projection when installed in a ceiling and horizontally when installed in a sidewall application. The pattern controllers permit angular discharge, allowing the airstream to be directed left or right in a ceiling application and up or down in a sidewall application. The pattern controllers also provide a variable aperture capability to adjust performance to specific applications.


  • Heavy wall extruded aluminum construction with galvanized steel pattern controllers.
  • Sliding pattern controller design provides easy adjustment for vertical directional control as well as a volume control capability.
  • Dual blade pattern controllers are constructed on 24" (610) centers as standard for maximum flexibility.
  • Five slot widths in a one or two slot configuration provide a high air volume capability.
  • Single section lengths up to 12 ft. (3658) reduce the number of joints in continuous runs.
  • Multiple section assemblies are divided into equal length single sections and are provided with alignment strips.
  • Mitered end borders on standard frame Type AA provide a superior architectural finish not available from several competitors.
  • FlowLine™ can be custom curved in any plane - concave, convex or flat radius.


  • FlowLine™ FLV Series is designed for continuous length installation in both hard drywall or acoustical suspension (T-Bar) ceiling systems. Optional mounting hardware is available to suit the installation method.
  • Available in two standard and various special frame/border designs to suit any installation requirement.
  • Various end border options are available to suit installation.
  • Mitered corner and transition sections are available.
  • Model Series FLP(I) factory engineered plenum boots are available, which ensure both a trouble free installation and that
  • catalog performance is met.
