Our Vanagon window duct flange allows you to pipe an external heat source or AC into your Vanagon via the driver's side sliding window.  Simply open the window, hinge the flange into place in the window track, and slide your window closed.

The 3" ducts are sized perfectly for the Propex PS2000 Portable Heater!

Will also work with other diesel heaters as long as duct outlets are 3" in diameter.

Ducting, Propex heater, and external AC not included.
