Air Inlet

The air inlet is installed at the window level (of a sliding door or roller shutter), whether it is a hygroregulated or self-regulating air inlet.
One part is to be screwed inside and another outside the wall crossing.
It allows for air renewal and regulates humidity in the home to avoid mold and bacteria.
A air inlet is not always acoustic; however, when it is, it reduces noise (for example, by 42 db).
Before purchasing this product, determine how many air inlets you need per room for your house or apartment.
You can also choose the color of the air inlets: white ABS, brown, etc.
