Roof Fans

• Two 12 volt MaxxAir Fan Deluxe 5100 roof fans

• Built-in rain guard

• Intake & exhaust modes

• 10 speed

• White finish to blend with the van roof

• One installed in the front near the kitchen and one in the back over the bed

• Pull fresh air into the van

• Remove odors and moisture

• Create airflow throughout the van

• Help regulate interior temperature

• Reduce condensation buildup

• Plan placement around other roof components and interior layout

• Measure twice, cut once

• Cutout size: 14” x 14”

• Apply painter’s tape to the van roof and the base of the jigsaw to prevent scratches and create a visual cutting guide

• Thoroughly clean all metal shavings inside the van and on the roof after cutting to prevent rust

• Paint the newly exposed metal with a rust preventative

• Use a fan adapter with 3M window-weld when installing on ribbed roof sections

• The fan consists of three main pieces: the fan unit, the roof flange that secures the fan to the van, and the interior trim ring that finishes the opening after the ceiling is installed

• Use butyl tape under the flange and self-leveling lap sealant on top to create a watertight seal and prevent leaks

• A roof fan circulates air but does not create cold air like an air conditioner

• Available with or without a remote control

• Available in black or white

• Install at least one fan, and up to two for improved airflow

• Use fan covers to block out light and help retain heat in colder weather

• A 12 volt roof fan is more efficient if you have a 12 volt battery bank, since no power conversion is required

• Cutting a hole in the roof reduces its structural strength, so be mindful when moving around on the roof to avoid damage

• After the sealant has cured for 24 hours, spray the area with water to test for leaks

• Install roof fans early in the build so metal shavings are easier to clean and the ceiling can be built around the fan

Since I don’t use the fans often, I’d prefer having colder air when traveling in warmer climates. For my next build, I’d install one roof fan in the front near the kitchen and an air conditioner over the bed instead of two roof fans.
