Polyaire's Outside Air Louvres (OAL) are designed to provide weather protection of outside air or discharge openings to allow free passage of air. These external louvres may also be used for natural ventilation.

The Small Section Outside Air Louvre(OAL-S) is normally used for small sizes and small air quantities.

Construction is from all extruded aluminium with a standard flange of 32mm.

A Bird screen of 12mm x 12mm square mesh is fitted to the rear as an option.

Standard finish is natural anodised while other finishes including powder coat are available to suit the interior and architectural design requirements.

The OAL-S is available in stock sizes and can also be manufactured to order in a wide range of sizes.
