DIYvan's patent pending roof vent adapter for Ford Tranist High & Mid Roof Vans fits a 14" x 14" opening. Please check your fan requirements. If it is 400mm x 400mm you need to purchase an adapter from our Euro Adapter listing at https://diyvan.com/products/ford-transit-euro-roof-vent-adapter-for-400mm-x-400mm-opening.
About our Adapter
Our Patent Pending roof vent adapter matches the contour of the OEM roof so a standard RV style vent mounts to a flat surface. Works with Maxxair Deluxe series, Fan-Tastic Vent fans, and the Airplus Deluxe vent fan.
Key Features of our Patent Pending Roof Vent Adapters:
- Custom Fit for Ford Transit Roofs: Matches the OEM roof contour, providing a flat surface for vent mounting.
- Prevents Roof Distortion: Avoids bending the sheet metal or vent flange during installation.
- Durable & Resilient Material: CNC-machined from UV- and fire-resistant expanded PVC for long-lasting performance.
- Ready to Use Template: Our adapter can be used as a template for cutting the hole in your roof to place your roof vent.
Check out the NEW Airplus vent fan we offer at https://diyvan.com/products/airplus-deluxe-roof-vent. The AirPlus Deluxe Roof Vent 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.
IMPORTANT TO NOTE:
- It is important to use our Interior Support Framing system with your van's roof vent adapter.Not all of the Transit vans are the same in the Most Forward area and may require more adhesive if there is a gap or some sanding on the adapter.
- The outside adapter will fit anywhere along the cargo part of the roof. Longer screws than came with the vent fan may be needed.
- The vent adapter outside dimension is 16 3/4 X 16 3/4. If you are using a Maxxair vent fan our adapter fits the Maxxfan Deluxe series, other Maxxair vent fans have a wider flange. You will need a wider adapter. Please text Kim at 541-490-4292 for help.
-
The option with butyl tape includes 64" of tape. If the butyl tape is stuck to the plastic, put it in the freezer for 30 minutes. It will release, then let the butyl tape return to room temperature.
- The level shown in the photo is not included.
We make roof vent adapters to fit air conditioners and adapters for offset locations. Please contact us so we can verify size and location.
Van Roof Vent Adapter Install Tips
We recommend Sikaflex 221.
- Locate and cut the 14 x 14 hole. You can use the adapter as a guide to mark the hole. Stay clear of roof support beams.
- Make a tape line 1/4" beyond the adapter perimeter.
- De-gloss the area with a Scotch-brite pad. No need to scuff, just dull the paint. Clean with isopropyl alcohol and let dry thoroughly. Blow dryer if it's wet and/or cold out.
- Apply three 1/8" beads of the Sikaflex on the face of the adapter. Then, press the adapter down onto the roof until the adhesive oozes out the sides. It's not necessary to clamp. If you do, use several lightly set clamps and spread out the clamp force over the whole surface area.
- Using the adhesive that oozes out, make a fillet around the adapter with a double gloved finger. Pull the tape within 15 minutes. Cure is fast on outside. Let cure overnight and then proceed with the fan install.
- If you purchased our Interior Framing Strips, using the hole that you cut locate where the transverse strips need to be placed on the longitudinal strips. Assemble the interior frame with the 2" screws provided. Once the frame is assembled it will be glued to the interior side of the roof using Sikaflex 221. If the strips ordered are not bay specific, then you may need to cut them to the length of the panel you are installing it in.
- We recommend using butyl tape for the fan install. Cover the fan flange with 1" wide tape. Place the flange onto the adapter and press down. Then drill pilot holes through the adapter and into the van roof. You may need the 4 longer screws provided for the corners. Tighten all screws very lightly against the fan flange. Some butyl will ooze out which you can trim off.
- Coat the fan flange, adapter and onto the roof about 1/2" with self-leveling Dicor or brush-on Flexseal. Some sealants will melt the fan plastic so you might try it on a portion of the interior bezel first. You will cut a lot of that piece off.
Good idea to check the integrity and reapply the sealant every so often.
**Please note, if you purchased butyl tape with this order and the butyl tape is stuck to the plastic, place it in the freezer for 15 or 20 min. It will release, then let it return to room temperature.
