Fan-Tastic Vent RV Roof Vent with Thermostat, Automatic or Manual Variable Speed 12 Volt RV Vent Fan, Automatic Dome Lift and Rain Sensor, Model 7350 (White) Review (2026)

Variable speed versus fixed speed steps

The Model 7350 is built around Dometic's Fan-Tastic Vent line and offers 14 fixed manual speeds along with a fully variable automatic mode, rather than the 3-speed step settings found on simpler models in the same lineup. In automatic mode, the fan adjusts its own speed to maintain the temperature you set, which removes the need to manually bump the speed up or down as conditions change throughout the day. For RVers who spend a lot of time in the rig during hot afternoons, that kind of hands-off temperature management can be more useful day to day than simply having a faster top speed, since the fan reacts on its own rather than waiting for someone to notice the temperature has climbed.

Digital thermostat control

A built-in digital thermostat lets you set a target interior temperature, and the fan automatically speeds up or slows down to hold that level, similar in concept to a small climate control system built into the vent itself. This is a meaningful step up from vents that only offer manual speed control, since it means the fan can keep working correctly while you are out hiking or running errands, cooling the RV before you return rather than leaving it to bake in a closed-up trailer all day. The digital readout also makes it easy to confirm the current setting at a glance instead of guessing at a dial position.

Automatic dome lift and rain sensor

The vent's dome lifts and lowers automatically as part of its operation, and a rain sensor with its own on and off switch is built in to close the dome if moisture is detected, protecting the interior if a storm rolls in while the RV is unattended. This combination of automatic dome control and rain sensing is one of the more established feature sets in the RV vent category, since Fan-Tastic Vent has offered rain-sensing dome lifts across several generations of its higher-end vents, giving the feature a longer track record than it would have from a newer manufacturer.

Fit, dimensions, and reverse airflow

The Model 7350 is sized for the standard 14 inch by 14 inch RV roof vent opening and includes a reverse switch to change airflow direction, so it can either exhaust hot air upward or draw in outside air depending on conditions. Listed exterior dimensions run around 16 and a half inches square by roughly 9 and a half inches tall once installed, and the unit runs on a 12 volt DC system in line with standard RV house battery wiring. As with any vent swap, confirming your existing roof opening and interior clearance before ordering avoids fit surprises during installation.

Price versus simpler Fan-Tastic Vent models

This variable-speed, thermostat-equipped model sits above the base 3-speed Fan-Tastic Vent options in both price and feature count, so it makes the most sense for owners who will actually use the automatic temperature control day to day rather than just running the fan on high or low. One tradeoff worth noting is that this listing does not mention an included wireless remote, meaning speed and mode changes are typically made at the fan itself or its wall-mounted control rather than from across the RV, unlike some competing vents that bundle a handheld remote. Owners who specifically want across-the-room remote adjustment should confirm that detail before buying.
