Frame: High quality aluminium sheet as standard. Steel construction as option.
Damper frame and blades: Steel sheet with black matt finish
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.
