Removable Core Linear Slot Diffuser (RC-LSD25)

Airfoil’s Australian Made premium Removable Core Linear Slot Diffuser (RC-LSD25) offers versatile air diffusion. Made from engineered aluminium extrusion, it suits both supply and return air applications. With a 25mm frame size and 50mm depth, this sleek diffuser is ceiling-mounted. The RC-LSD25 features a spring-clipped outer frame for easy installation, with the centre core clipping into place. Internal black “J” blades in a 19mm “T” bar extrusion adjust up to 180 degrees for flexible air throw patterns. Its 25mm slot design ensures greater air volume per slot and reduced noise.

The RC-LSD25 can accommodate up to 6 slots, with 1 to 4 slot models available in lengths up to 4 metres, and 5 or 6 slot models in 2.5 metre sections due to weight. It includes a Safety Chain and Swivel Safety Bracket. Joining strips create seamless longer runs. Available in white powder-coated or natural anodised aluminium silver finish, it can also be customised to any colour. Ideal for perimeter offices, airports, corridors, hospitals, shopping centres, cinemas, and any setting requiring variable air patterns.
