Description

DIYvan's patent pending roof vent adapter for the Westfalia Vanagon for a 11" x 11" opening. Many Vanagon owners have a desire to replace the skylight that is on this van and replace it with the fan.

About our Adapter

Our Patent Pending roof vent adapter matches the contour of the OEM roof so a vent mounts to a flat surface. This adapter works with a NomadicArk 280 x 280 Turbo Fan. It may work with other fans with a 11" x 11" opening. It would be best to reach out to us to verify before ordering this one.

Key Features of our Patent Pending Roof Vent Adapters:

Custom Fit for Westfalia Vanagon 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.

Van Roof Vent Adapter Install Tips

We recommend Sikaflex 221.

Locate and cut the 11 x 11 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.
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.
