Round Ceiling Diffuser – Adjustable Core

Product Description


Description:

  • Frame and inner cones of round ceiling diffuser is made of high quality aluminium sheet construction with the advantages of corrosion resistance and rigidity.
  • Inner cones fixed centrally to the frame. Cones can be taken out by pushing inward, turn around and pull down. This provides easy installation, maintenance and access to the duct.
  • Radial, opposed blade damper is fixed to the frame by rivets. Damper can be operated by screw through diffuser face.
  • Foam gasket is sealed around the back of the frame as option to avoid air leakage.
  • Discharge pattern can be adjusted for horizontal flow by extending the cones and for vertical flow by retracting the cones.
  • Can be used for ceiling or exposed duct mounting especially in installation when an adjustable pattern is required.

Standard finishes:

  • Aluminium construction with white powder coated color finish (RAL 9010).
  • Steel construction with white powder coated finish (RAL9010)
  • Powder coated color finish as per other RAL color codes available as option.

  • N = Nominal size.
  • 630 mm dia diffuser available only in steel.
  • All the dimensions are in mm.

Air pattern:

Horizontal air pattern

  • Pattern is obtained by extending the cones downwards.
  • This arrangement handles more capacity of air with increased induction and uniform air distribution.

Vertical air pattern

  • Pattern is obtained by retracting the cones upwards.
  • Air is delivered vertically without much induction.
  • Suitable for localized cooling in conditioned area and for higher altitudes

FIXING:

  • ARD: Concealed screw fixing from neck of the diffuser to the duct after removing internal cones.
