Window air vent

This is a replacement for a window air vent installed by a window replacement company. It can also be mounted to balcony doors.


It should be mounted in the upper part of the window closer to the opposite side than the hinges.
Before installation, cut out the window/balcony door seal in two places:
- on the window frame in the lower part, next to the hinges
- in the window sash in the same place as the window air vent
