Slot diffuser with three adjustable slots L = 1000 mm

The SLS13 aluminium slot diffuser comes with adjustable 1000 mm slots 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 slots can be adjusted individually, and each comes with 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 SLS13 slot diffuser is suitable for ceiling or wall installation. Either the insulated or non-insulated SPS plenum box is recommended/used for installation.
