Tilt Window Exhaust Hose Adapter + Louver Front

Tilt Window Exhaust Hose Adapter

This adapter guides exhaust and ventilation air safely outside through a tilted window and connects to standard 100 mm exhaust hoses.
It clamps into the window gap and provides a stable, removable solution without requiring drilling or permanent window modifications.

Hose Connection

• Designed for 100 mm exhaust hoses
• Tapered inlet from 98 mm to 100 mm
• Connection length: 26 mm

Optional Louver Front

An optional louver front piece can be attached to the adapter:

• Allows placing an insect protection mesh behind the louvers
• Helps deflect rain, reducing the chance of water entering the exhaust hose
• Can be used with or without the louver piece

The louver front is printed separately.

Louver Mounting

• Secured with 2 × M3 screws
• Minimum screw length: 8 mm
• If using M3 nuts, use 12 mm screws

Window Requirements

To fit correctly, the window must open wide enough so the adapter can be inserted at an approximate 45° angle.
This angle refers to the adapter orientation, not the opening angle of the window itself.

Required opening width:

• Upper part of the adapter: approx. 50 mm
• Lower part of the adapter: approx. 43 mm
• Required opening height at the insertion area: approx. 200 mm

Printing Notes

• Total parts: 2 (adapter + louver front)
• The main adapter requires minimal support only
• The louver front does not require any supports
• Recommended material: PETG or ASA for better outdoor resistance
• PLA is suitable for indoor or temporary use
