 Curved Duct Grille  A to Z Products
 Introduction
 
SINGLE DEFLECTION CURVED DUCT GRILLES
 
COSMOS single deflection curved duct grilles and registers are recommended for applications requiring pattern adjustment in a single horizontal or vertical plane.

The innovative design incorporates a unique frame rolled to match the required duct radius. The grille frame mounts flush with the spiral/curved duct.
COSMOS make model CDG‐HF is a curved duct grille with fixed horizontal bar blades and model CDG‐HA is a single deflection curved duct grille with horizontal adjustable blades. Horizontal blades will control the rise and drop of the air pattern, typically cool air upwards along the ceiling. Model CDG‐HF is horizontal fixed blade type curved duct grille.

Spacing between the blades is 20mm, thus maintains high effective area, which minimize outlet velocity, reduce pressure drop and assures quite operation.

COSMOS models CDG‐HF‐D and CDG‐HA‐D are curved duct grilles with integral volume control damper. Dampers are opposed blade design with screwdriver slot operator
 
 
  Features
 
High quality, extruded aluminum construction.
27mm and 16mm rolled form flange to match required duct radius.
Rigid, heavy gauge extruded frame with reinforced mitered corners.
A single set of individually adjustable and friction pivoted.
Extruded blades on 20mm centers. Blades positively hold deflection setting under all conditions of velocity and pressure.
Aluminum integral dampers are opposed blade design with screwdriver slot operator.
Adjustable air pattern – Blades are friction pivoted and easily adjusted to provide desired spread or deflection.
 
  Finish
 
Standard RAL 9016 powder coated. Collar damper in matt black shade. Other finishes available on request.
 
DOUBLE DEFLECTION CURVED DUCT GRILLES
 
 
COSMOS double deflection curved duct grilles and registers are recommended for applications in systems requiring maximum flexibility.

The innovative design incorporates a unique frame rolled to match the required duct radius.The grille frame mounts flush with the spiral/curved duct. Front set of blades has the greatest effect on the air pattern and therefore should be selected based on particular requirements.

Model CDG‐HVA is also a double deflection curved duct grille with front horizontal adjustable blades and rear vertical blades. Horizontal blades will control the rise and drop of the air pattern, typically cool air upwards along the ceiling.

Spacing between the blades is 20mm, thus maintains high effective area, which minimize outlet velocity, reduce pressure drop and assures quite operation.

COSMOS model CDG‐HVA‐D is double deflection curved duct grilles with integral volume control damper. Dampers are opposed blade design with screwdriver slot operator.
 
  Features
 
High quality, extruded aluminum construction.
27mm and 16mm rolled form flange to match required duct radius.
Rigid, heavy gauge extruded frame with reinforced mitered corners.
A dual set of individually adjustable and friction pivoted.
Extruded blades on 20mm centers. Blades positively hold deflection setting under all conditions of velocity and pressure.
Adjustable air pattern – Blades are friction pivoted and easily adjusted to provide desired spread or deflection.
 
  Finish
 
Standard RAL 9016 powder coated. Collar damper in matt black shade. Other finishes available on request.
