Expella Shadowline Pro Internal Ceiling Diffuser – Linear 1200 150mm Duct

The Expella Shadowline Pro Diffuser is a concealed flangeless internal grille featuring a modern aesthetic, built with custom aluminium extrusion for maximum performance and ease of installation. Designed to allow air to be channelled through, the unit works well with bathroom inline ventilation or air conditioning systems. It has a discreet application as positioning at a wall/ceiling junction creates a shadow line detail that conceals the ventilation system.

It comes with an adjustable aperture suitable for diverse wall finishes and thicknesses, ensuring a consistent finish with gyprock and tile installations running inside the diffuser opening when placed at a wall/ceiling junction. The modular design gives it more adaptability, allowing the unit to be cut or extended and fit different length requirements. Additionally, the Shadowline Pro Diffuser is designed to accommodate an LED strip to provide a subtle ambient lighting effect.
