Single Deflection Grilles & Registers

Single deflection supply grilles and registers are recommended for sidewall applications requiring pattern adjustability in a single horizontal or vertical plane, sill or sidewall location at ceiling line, or heating application only.

The combination of streamlined foil shaped fins and 17 mm (2/3-inch) fins spacing maintains a high effective area capacity of greater than 80% which minimizes outlet velocity, reduces pressure drop and assures quiet operation. Individually adjustable fins are capable of shortening throw up to one-half with a wide spread deflection requiring only a 20% increase in outlet velocity at a fixed volume.

GAA Series (aluminum) have extruded aluminum frame with roll formed aluminum fins.

GSA Series (steel) have extruded aluminum frame with steel fins. This unique feature combines the beauty and rust resistance of the aluminum frame with the rigidity of steel fins.

GENERAL FEATURES

• Fully adjustable fins.
• Same extruded aluminum frame for both GSA and GAA.
• Available with horizontal face (blades parallel to long dimension) or vertical face (blades parallel to short dimension).
• Powder paint coating – White (other colors available upon request).
