Slot diffuser with single adjustable slot L = 800 mm

The SLS11 aluminium slot diffuser comes with an 800 mm adjustable slot and is suitable for both supplying and extracting warm or cool ventilation air. This adjustable slot diffuser is widely used in homes, offices, shops, meeting rooms, and so on. The air slot can be adjusted separately, and each has two specially designed low-profile deflectors. This means the airflow supply can be adjusted by up to 180°.

These hidden deflectors ensure that the slot diffuser keeps its sleek design. The Grada SLS11 slot diffuser is suitable for ceiling or wall installation. Either the insulated or non-insulated SPS plenum box is recommended/used for installation.
