Double Deflection Grilles

Double deflection grille incorporates two sets of individually adjustable blades.

Aerodynamically shaped components reduce noise and improve air flow characteristics.

The front blades may be either horizontal or vertical.

Adjustable blades allow horizontal or vertical adjustment in either direction, symmetrically or asymmetrically. Adjustability changes throw length, direction and the airflow patterns shape.

The grille is suitable for sidewall, soffit or sill mounting and may be used for supply or extract applications.
