Mercedes Metris Roof Vent Adapter

Check out the NEW Airplus vent fan we offer. It has more features than the Maxxair, a brushless motor and it does not rattle! By far the best!! The fan adapters also work with the  Maxxair Deluxe series and the Fan-tastic Vent fans. Patent Pending adapter matches the contour of the OEM roof so a standard RV style vent mounts to a flat surface.  Prevents distorting the roof sheet metal or vent flange and can be used as an aid for locating the fan. They are CNC machined out of UV and fire resistant expanded PVC. The fan mounts to the outside adapter.  Fits a 14" x 14" opening.  Longer screws than came with the vent fan may be needed. The interior framing strips will need to be cut to length. They are glued in with Sikaflex 221 or the like. ****The vent adapter outside dimension is 16 3/4 X 16 3/4.   If you are using a Maxxair vent our adapter fits the deluxe series, other Maxxair vents have a wider flange. You will need a wider adapter. Please call. Roof Vent Adapter Install Tips
