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 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.

 

Other Velux window types with a confirmed fit:

  • GPU SK06 (by Stetim87)

No commercial license available for this model. Any unauthorized reseller without my permission for reselling will be reported.

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.
