Description:
-
Frame and inner cones are 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.
|
|
-
ARDF: Screw fixing.
-
ARD: Concealed screw fixing from neck of the diffuser to the duct after removing internal cones.
