RC Steel Diffuser

Square/ Round Diffusers

Available in 1, 2, 3 or 4-way patterns to suit any space condition, the Agitair® RC diffuser need not be centrally located in an area. It can be installed in various locations and the air pattern control feature gives design freedom and frequently reduces costly duct runs.

  • Has an internal duct connection that reduces leakage
  • Features an all-steel construction
  • Rolled-edge louver gives it a smooth and finished appearance

RC Steel Diffuser

    Product Application

    Creating a comfortable environment that ensures the occupants’ satisfaction is our priority. To achieve this goal, we have designed the RC Steel Diffuser which creates a draft-free environment with thermal comfort and equalized air distribution. The 64 active air jets per square foot featured on the diffuser produces numerous counter flowing air streams, creating a higher degree of turbulence at the point of discharge. This results in aspiration, rapid mixing, and temperature equalization.
    Product Application

    Features

    • Removable core available in 1, 2, 3 or 4-way diffusion patterns
    • Duct mounted opposed blade damper (DOBD), square to round transitions (SRR), steel plaster frame (SMF), and aluminum plaster frame (ASMF) available as accessories
    • Matching returns (less air diffusion vanes) are available (RCR & ARCR)
    • Available in a large range of sizes of width 6" to 48" in 1-1/2" or 3" increments and height 3" to 36" in 1-1/2" or 3" increments
    • Margin styles to fit most ceiling types and systems
    • Optional shock and vibe (S&V) construction available
