It has been said before, but unless you are building a 60 Sq Ft rolling mold farm then it is very important that you incorporate a roof vent fan into your Campervan Ventilation System. The addition of a roof vent fan to your build will assist with air flow and in turn help regulate temperatures and minimize condensation inside your van.
Campervan Ventilation – The Benefits Of Installing A Roof Vent Fan
Air Circulation And Air Exchange
No one likes to be in a hot and stagnant environment. Without a roof vent, your van is basically a big steel solar oven. If parked in the sun on a warm day, temperatures inside your van will quickly raise well above the outside ambient temperature. Not a nice place to be. With the addition of a roof vent fan, you will have the ability to quickly evacuate hot and stale air and maintain a temperature similar to outside your van.
Regulate Humidity And Limit Condensation
Just by living we are constantly creating moisture. Breathing, sweating, damp gear and cooking all produce moisture and humidity. The amount of humidity in the air has a direct effect on the amount of condensation that will form inside your van. Higher humidity levels will also affect your physical comfort when hanging out in the van. Being able to exhaust all that moist humid air will allow you to keep your van feeling as fresh as possible.
Although it won’t have quite the same effect as an Air Conditioning unit. Having a roof vent fan will help you regulate the inside your van. Some install intake vents in the floor of their van so as to bring in cooler shaded air from the underside of the van.

This option from Eurocampers.com is a perfect non-permanent ventilation option. Easy to install and remove, Louvered Vent Window Inserts would be a great match with a powered roof vent fan. We have a set of these for our Promaster
Fan Forced Roof Vents are by far the best and most highly recommend choice for the primary vent in your Campervan Ventilation project. Being able to force air in or out of your van will give you the best possible air flow. This will give you the highest levels of air exchange to facilitate removal of excess humidity.

Campervan Ventilation – Intake Considerations
Something to remember when designing and installing your Campervan Ventilation. For the system to perform optimally, air needs a way into the van as well as out. You could just crack a window when you operate your fan but this is not ideal. An open window can lead to security and water intrusion problems. The best option is to install an intake vent to work in conjunction with with your roof vent fan. You can use any one of the vents listed above.

Now that you have your Campervan Ventilation System in check be sure to start planning your Insulation and Sound Deadening. Insulation and Sound Deadening are just as important and not to be overlooked.
