Air intake in outside walls of buildings - has S-shaped air deflection channel with sound/heat absorption, and air volume limitation unit with filter for regulation from zero to max.
Air intake in outside walls of buildings - has S-shaped air deflection channel with sound/heat absorption, and air volume limitation unit with filter for regulation from zero to max.
The device (1) has a cube-shaped housing (10) with an approx. S-shaped air deflection channel (11). The channel is lined with sound and heat absorbent material (12). Air flows through the channel into the interior. The channel section (110) leading to the outside contains an air volume limitation unit (2) with filter (22). The unit regulates the air from maximum, when the profile is fully open, and zero, when it is closed. The filter is mounted on an air-permeable carrier. It can be replaced from the room interior without tools. The air flow limiter is covered by a sound and heat absorbent material (21) on the side into the room. USE/ADVANTAGE - Domestic flats, houses. Has good heat insulation and effective regulation of air volume, filter can be replaced quickly and easily.
