A vent with sense

The powerful yet compact Dometic Fantastic Vent has fixed, manual speeds or automatic variable speeds to get the airflow precisely as you want. Its simple reverse switch changes the fan direction, drawing air in or out of the vehicle. On some models - the rain sensor automatically closes the dome when wet – keeping you and your vehicle interior dry! Alternatively, users can easily operate the dome by switch. For true comfort at your convenience, the Fantastic Vent has an built-in thermostat to take care of maintaining your desired temperature.

A vent with sense

Achieve the ideal on-board temperature

Potential problems associated with vents on an RV are: allowing rain in and struggling to maintain a constant, comfortable temperature. The FanTastic Vent is a high-powered vent fan that solves both these issues and neither require the user's assistance! Firstly, a thermostat is used to maintain the desired temperatures in your vehicle. Then, in case of rain, the rain sensor will automatically close the dome when wet. All you need to do is relax and enjoy the comfort of your RV – fair deal?

Achieve the ideal on-board temperature

Fan-tastic airflow

Warm and stale air out, fresh and clean air in. Dometic Fan-Tastic vent model 3350 exchanges air quickly, quietly and efficiently. This ventilation solution has a built in thermostat that allows you to adjust the temperature setting. Simply set the desired temperature on the remote control and the fan motor will start and stop automatically as the interior temperature of the vehicle exceeds or drops below the set temperature. A rain sensor will automatically close the dome when it starts to rain, keeping you and the interior of your vehicle dry.
