If there's one upgrade that makes van life more comfortable in every season, it's a quality roof vent fan. In summer it pulls hot air out and keeps you sleeping. In winter it controls condensation from cooking and breathing. On rainy days it lets you ventilate without getting wet.
Three brands dominate the van life market: Maxxair, Fan-Tastic, and Dometic. Here's how they compare.
The Main Contenders
Maxxair 00-07500K MaxxFan Deluxe
The Maxxair MaxxFan is the most popular van vent fan for a reason. It can be opened and run in the rain (the fan lid opens at an angle that deflects water), it has 10 fan speeds, it moves a serious amount of air, and the manual override means it still works even if the motor fails.
The remote control works reliably, the thermostat function is genuinely useful for overnight temperature management, and installation is straightforward for a first-time builder. At around $200–250, it's excellent value.
Best for: Most van builds. It's the default recommendation for good reason.
Fan-Tastic Vent 7350
The Fan-Tastic 7350 is the quietest vent fan we tested — noticeably quieter than the Maxxair at equivalent airflow speeds. It also has a rain sensor that automatically closes the lid when it detects rain, which is a genuinely useful feature if you're not always in the van.
The downsides: it can't be run with the lid fully open in rain (the rain sensor closes it), and the remote is less reliable than Maxxair's. It's also slightly more expensive at $250–300.
Best for: Light sleepers, stealth builds where noise matters, or builds where you're frequently away from the van.
Dometic FreshJet / Fan-Tastic Owned by Dometic
Dometic now owns the Fan-Tastic brand, and their premium vents offer the best build quality of the three. The lid mechanisms are more robust, the fan motors tend to last longer, and the product support is better. For full-time van lifers who expect years of daily use, the Dometic premium is worth it.
Best for: Full-time van lifers prioritising longevity over initial cost.
Installation Tips
- Cut your roof hole with a jigsaw and metal cutting blade — measure three times
- Use Dicor lap sealant (not silicone) around the flange for a watertight seal
- Install a fan cover/vent hood if you're in a high-theft area or doing high-speed highway driving
- Position the fan over your main living area, not your cab — you want to pull air through the van from front to back
- Two fans (one intake, one exhaust) dramatically improves airflow for summer van life
One Fan or Two?
One fan handles most people's needs well. Two fans (positioned front-to-back with one pulling air in and one pushing air out) creates a through-breeze that makes a significant difference in summer. If you're building a permanent home in a warm climate, budget for two from the start rather than cutting a second roof hole later.
