Airfoil’s Australian Made premium Linear Slot Diffuser with Plaster Mounting Frame (LSD20-PMF) offers adaptable air diffusion. Made from engineered aluminium extrusion, it suits both supply and return air applications. With a 28mm frame size and 50mm depth, this sleek diffuser is typically ceiling-mounted. Installation is straightforward with a two-step process. First, the clip-in Plaster Mounting Frame is secured, then the unit clicks into place for a seamless finish. Internal black “J” blades in a 19mm “T” bar extrusion adjust up to 180 degrees, providing versatile air throw patterns. Its 20mm slot design delivers greater air volume per slot and reduced noise.
The LSD20-PMF accommodates up to 6 slots, with 1–4 slot models available in lengths up to 4 metres, and 5–6 slot models in 2.5 metre sections due to weight. It includes a Safety Chain and Swivel Safety Bracket, with joining strips available for longer runs. Finished in white powder-coat or Natural Anodised silver, it can also be customised to any colour. Ideal for offices, airports, hospitals, shopping centres, cinemas, corridors, and other commercial or domestic applications requiring variable air pattern
