Double Deflection Grilles & Registers

Double-deflection supply grilles and registers are recommended for sidewall application in systems requiring optimum flexibility of pattern change to accommodate changing job conditions.

The combination of streamlined foil shaped bars and 17 mm (2/3-inch) bar spacing maintains a high effective area capacity of greater than 80% which minimizes outlet velocity, reduces pressure drop and assures quiet operation. Individually adjustable bars 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 bars.

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

GENERAL FEATURES

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