Set of ventilation devices for mounting in groove in window or door frame, has ventilation channel in each device defined by pair of interconnected profiles

摘要

Each device (100A-100C) includes two profiles (104, 105) secured directly to each other and a ventilation channel (101) is created by altering the position of one of these profiles. The channels in all the devices are geometrically identical and have approximately the same through-flow characteristics. The device includes a groove (102) for engaging with a window pane or filler panel, as well as a clamping edge (103) for securing the device inside the groove in the frame. The device also has two or more end pieces. Each device has a different groove and clamping edge having a width matching the thickness of the pane or filler panel thickness.
