Exhaust air system DF1 double window size 1 = 44-61 cm window height - Kopie

Air extraction system double doors terrace or balcony standard

Exhaust air system for balcony/terrace doors, 199 - 270 cm door height, the "gap" between the two doors is at least 2.5 cm wide...

The exhaust air hose is hung on the side with the pre-assembled adapter in the side panel. It can be hung up again at any time, e.g. if both doors are to be fully opened or if exhaust air operation is not desired.

The exhaust air system consists of the two side panels with the associated threaded rods for bracing the system, a 2-part panel for the upper door cover, the plastic adapter for exhaust air hoses Ø 150mm, all necessary screws, sealing brushes for gluing and tools. Each set is complete for one door.
Structure (schematic):

First, the side panels are mounted according to the assembly instructions. They are firmly clamped between the floor and the lintel using the threaded rods you have pre-assembled. No gluing or drilling is necessary. The firm hold is provided exclusively by the clamp.
The two halves of the upper grille can be precisely adjusted to the width of the door by sliding them into each other and are screwed tight with the screws provided.
Now stick the sealing brushes on the hinge side and above the door to the cover.
Fasten the plastic adapter to your exhaust hose, hang it in the side panel, done.

The exhaust air system can remain installed all year round. The assembly and disassembly effort is low.
