Enjoy Year-Round Comfort With A Van Roof Vent
Ventilation is vital for anyone planning a van life adventure in a hot climate or with a pet on board. Essentially, a roof vent fan keeps your cabin cool by extracting heat as it rises to the top of your van, in turn drawing in cool air from below. It also sucks up any steam and scents while you cook, helping to remove excess moisture that can otherwise lead to issues like mould or rust.
The bottom line: A roof vent fan promotes airflow within your living space. That means you can enjoy fresh, clean air inside your van, no matter the weather.
So which type of van roof ventilation is right for you? It all depends on your travel lifestyle and layout. For instance, while a remote-controlled fan with sophisticated temperature control is great for a high-top van and summer camping trips, a more basic, affordable fan might be a better option if your destination has a mild climate.
At the end of the day, every aspect of your van conversion is your call - and ventilation is no exception. To help you decide on the best roof ventilation fan for your van, we’ve weighed up some of the most popular models on the market!

Things To Consider When Buying A Roof Vent Fan
Energy savings translate into dollar savings, which means more money to spend on other aspects of your van conversion! The lower the vent fan’s amperage draw, the less energy it consumes. Of course, you should consider the size of your van when determining how much power you’ll need to cool it down.
The amount of air that a vent can shift, i.e. its efficiency, is measured in cubic feet per minute (CFM). In general, the higher the CFM, the better and more expensive the fan. The good news is that if you’re converting a smaller van, you won’t require as high a CFM for sufficient ventilation.
The more time you plan to spend inside your van, the more important a ventilation system. Trust us, living in a stuffy, sweltering hot van is not fun! That said, if you’re only going to be taking your van away for the odd weekend, you may be able to get away without one. It’s all down to personal preference.
Different vent fans come with different designs, advantages and extras so you need to decide which features you value most. As with all things van conversion, ventilation can be personalised to your needs and wants. Read on for a more detailed breakdown of our favourites!

Installing Your Roof Fan

Slashing a big hole in your beloved van’s roof is scary business. But we promise it’s worth it (and even a little fun, once you embrace the slice!). What’s more, you can install your vent fan in just five simple steps.
1. Marking The Hole
Do NOT freestyle this step! Instead, mark the area where you plan to install your fan. To do this properly, either use the provided template (which is only included with some fans), or trace a measured shape onto your roof with a plastic trim piece.
2. Joining The Dots
For a smooth slice, drill a hole at each of the four corners of your marking before connecting each one with a jigsaw.
3. Mounting The Flange
Most fans include sheet metal screws, but these do not attach to fiberglass very well. For a sturdy mounting you can count on, line the hole with VHB Tape and insert the flange before drilling in screws around the edges. Then cover its perimeter with lap sealant.
4. Inserting The Fan
Attach your vent fan to the flange with screws.
5. Wiring The Fan
Use twist connectors to attach wires to your fan before wrapping them with electrical tape. Make sure to label these wires for easy identification (future you will really appreciate it) and then run them through the hole down into your van for later electrical setup.

Now that your fan is securely attached to the roof, all you have to do is wire it up to your power system. Check out our handy tips on solar and electrical installation to get your van’s ventilation well and truly flowing!
