Curved Spiral Duct Grille

Models: 61SVC and 61SHC

Models 61SVC and 61SHC Curved Spiral Duct Supply Grilles are for use in exposed spiral duct applications requiring adjustment in a single horizontal or vertical plane. The vertical blades will control the spread and throw distance of the air pattern to accommodate various layouts. Horizontal blades will control the rise and drop of the air pattern, typically directing warm air downwards or cool air upwards. The innovative design incorporates a unique one piece frame, rolled to match the required duct radius, which eliminates any visible lines in the corners of the grille, enhancing the appearance. The grille frame mounts flush with the spiral duct and thus reduces the labour and installation cost by eliminating the need to fabricate stand-off saddles.

Models: 61DVC and 61DHC

Models 61DVC and 61DHC Curved Spiral Duct Supply Grilles are for use in exposed spiral duct applications requiring maximum flexibility. The front set of blades has the greatest effect on the air pattern, therefore should be selected based on particular requirements. Vertical front blades will control the spread and throw distance of the air pattern where as horizontal front blades will control the rise and drop of the air pattern, typically directing warm air downwards or cool air upwards. The innovative design incorporates a unique one piece frame, rolled to match the required duct radius, which eliminates any visible lines in the corners of the grille, enhancing the appearance. The grille frame mounts flush with the spiral duct and thus reduces the labour and installation cost by eliminating the need to fabricate stand-off saddles.
