When designing high performance HVAC systems for upscale residential and modern commercial spaces, standard stamped metal grilles often fail to meet both airflow efficiency requirements and architectural standards. Linear bar grilles offer a crisp, continuous line aesthetic without sacrificing static pressure management or free area ratio.
Architectural Grille offers two stand out linear bar grille models: the AG10 and the AG20. Both series share durable aluminum construction and a variety of premium factory finishes, but their internal deflection dynamics serve distinctly different air distribution functions.

AG10 B Bar Linear Grilles
The AG10 Bar Grille features parallel bars set at a 0° deflection angle. This straight blade orientation provides an unobstructed path for air entering or leaving the duct work, making it the premier choice when high volume airflow and maximum throw distance are required.
- Higher Free Area Ratio: Because the bars stand perfectly straight, the effective free area remains maximized. This reduces static pressure drops across the grille face, permitting lower fan speeds and reduced overall sound levels (NC/RC ratings).
- Deep Room Penetration: Ideal for high-ceiling supply applications or sidewall registers where air needs to travel deep into a space before mixing.
- Symmetrical Aesthetic: The straight 0° bar arrangement creates clean sightlines regardless of the viewing angle, perfect for modern linear ceiling runs.

AG20 B Bar Linear Grilles
The AG20 Bar Grille utilizes blades set at a 45° deflection angle. This fixed pitch provides the highest degree of deflection available by Architectural Grille.
- Targeted Air Streams: Perfect for sidewall or sill applications where supply air needs to be directed away from occupants, draft-sensitive areas, or glass windows to prevent condensation.
- Sightline Concealment: The 45° angled blades serve as an effective visual baffle. When looking straight at the unit, interior ductwork, plenum boxes, and rough openings remain hidden from view.
- Downward or Upward Diversion: Depending on installation orientation, the AG20 can direct conditioned air down toward the occupied zone from a high wall or throw air up along a window curtain wall.

Custom Ordering
While the AG10 and AG20 models come in standardized dimensions, Architectural Grille also provides fully custom fabrication across their extensive linear bar, perforated, and decorative grille lines. Exploring their project inspiration gallery offers a helpful look at how these custom profiles integrate into complex architectural spaces. Custom ordering also opens up material selection beyond standard aluminum, allowing you to specify high-grade bronze, brass, or stainless steel to meet precise structural and design requirements.
