Slot diffuser with four adjustable slots L = 500 mm

The SLS14 aluminium slot diffuser comes with adjustable 500 mm slots and is suitable for both supplying and extracting warm or cold ventilation air. This adjustable slot diffuser is widely used in homes, offices, shops, conference rooms, and so on. The air slots can be individually adjusted, and each has two specially designed low-profile deflectors. This means the air supply flow can be adjusted by up to 180°.

These hidden deflectors ensure that the slot diffuser keeps its sleek design. The Grada SLS14 slot diffuser is suitable for ceiling or wall installation. Either the insulated or uninsulated SPS plenum box is recommended/used for installation.
