The new wall-mounted diffuser can be used for both supply and extract of air in indoor environments; consisting of an aluminium "screen" and "frame", the latter equipped with a "guide" to adjust in 4 positions ("steps" with a 7.5 mm pitch between each) the recess of the screen with respect to the 3rd step (true "flush with the wall" position) and thus the air flow. The 1st step corresponds to the closed position.
A 4th step, outside the wall, is available if higher air flow rates than "flush with the wall" are required.
FRAME THICKNESS: 17 mm.
The screen is easily removed and inserted for cleaning.
