The Double defection grilles are designed for use in supply and return air applications. Double deflection grilles have either vertical front blades and horizontal rear blades or horizontal front blades and vertical rear blades. All grilles feature attractively designed extruded aluminum features. The blades are aerodynamically designed to provide optimum air flow and low sound pressure level performance.
Features: 1. made of 100 percent hardwood (such as Eucalyptus, Gurjan, Birch,etc); 2. High density and long lasting, more stable performance; 3. Stronger and harder, more durable in use; 4. Finer Grain, natural wood grain.
Plywood made from hardwood timber are generally heavier in weight, higher in density and have much longer life than other timber species such as rubber wood or poplar softwood plywood.
