Velux GPU MK04 window exhaust adapter
Print Profile(2)
Description
New better version available here (only for the P2S, X2D and H2, not for AC units):
New better version for AC units available soon
I needed a adapter for my X2D so I can exhaust the fumes out the window.
- This exhaust adapter is designed for the Velux GPU MK04 for a 120, 130, 140 or 150 mm hose.
- The height of the opening can is 25mm. I have added a quick print fitting mold if you want to check first if it will fit.
- It works simply with a perfect fit in the grooves and closing the window.
- I suggest adding some felt pads like shown in the picture for a even better fit.
Other diameters and widths can be made on request. It might fit similar Velux roof windows as well, I have not tested that.
If you connect a airconditioning unit with a large hose (140mm or larger) you need a large opening for undisrupted airflow, otherwise the AC unit can overheat. A better version for AC units is available soon.
Other Velux window types with a confirmed fit:
- GPU SK06 (by Stetim87)
Change log 11-07-2026:
- Removed the rib on top because it has a better fit on different windows without.
- Added small designer tag on the side because people are selling my design without permision.
