Single Deflection Grille

Models 51SV and 51SH Single Deflection Supply Grilles are recommended for applications requiring pattern adjustment in a single horizontal or vertical plane.

They are generally used in a high side wall application where 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 along the ceiling.

The combination of streamlined ‘teardrop’ shaped blades and 19mm spacing maintains a high effective free area average capacity of 75%, which minimises outlet velocity, reduces pressure drop and assures quiet operation.
