Long-Throw Air Distribution for Large Spaces

The OND Drum Diffuser is purpose-designed for venues with high ceilings and expansive floor areas — including sports halls, airport terminals, atriums, and industrial factories — where air must be projected horizontally over long distances to achieve uniform temperature and velocity conditions throughout the comfort zone.

Adjustable Blade Design and Finish Options

The OND features a horizontal discharge configuration with the ability to rotate ±30° on the horizontal axis, giving installers the flexibility to direct airflow precisely where it is needed. Manually adjustable blades allow the discharge angle to be repositioned between summer and winter settings — ensuring effective mixing in both heating and cooling modes, and allowing air to reach zones that would otherwise be poorly served.

The casing, drum body, and blades are all fabricated from specially extruded aluminum profiles, combining light weight with long-term structural rigidity. Standard powder coat finishes are RAL 9010 and RAL 9016; alternative RAL colors, matte anodized, and raw aluminum finishes are available to match specific architectural or interior requirements.

Where volume control is required, a color-matched opposed blade damper can be fitted and adjusted using a dedicated damper key, providing a clean, tool-free solution for on-site airflow balancing without removing the diffuser from the duct.
