The Dometic Fan-Tastic Vent is a recreational vehicle (RV) ventilation system designed to provide maximum airflow while offering protection from the elements. It is intended for use in RVs and comes in various models, including manual lift, automatic lift, and models with remote or wall-mounted controls.
The primary function of the Fan-Tastic Vent is to circulate air within an RV, either by exhausting stale air out or drawing fresh air in. This helps to maintain a comfortable ambient temperature and improve air quality inside the vehicle. The fan operates on 12 VDC power and is designed to run on filtered DC current.
The vent features a dome (lid) that can be opened and closed to allow or restrict airflow. Depending on the model, the lid can be opened manually or automatically. Many models include a thermostat, allowing the fan to automatically turn on or off based on the interior temperature of the RV. This feature helps to regulate comfort levels without constant manual adjustment.
Some models are equipped with a fan blade motor-reversing switch, enabling the user to choose between "OUT" (exhaust mode) to expel hot, stale air, or "IN" (intake mode) to draw fresh air in. The intake mode can effectively pressurize the coach if all windows, doors, and other vents are closed.
Several models also incorporate a rain sensor. When moisture contacts the sensor, the lid automatically closes, and the fan motor disengages to prevent water from entering the RV. Once the rain sensor dries, the lid will not automatically re-open; it requires manual intervention or a specific command from the control unit to re-open. Manually opening the lid when the rain sensor has activated will bypass the sensor, allowing the fan to operate according to its previous settings. The rain sensor will reactivate once it dries.
The Fan-Tastic Vent offers a range of usage features depending on the specific model:
Manual Lift Vents:
Automatic Lift Vents and Controlled Models (e.g., Models 6300, 6350, 7300, 7350, 5300, 5350, 5200, 5250, 4200, 4100, 4150, 4175, 3300, 3350, 4201, 4251, 4301, 4351):
The manual outlines several maintenance procedures to ensure the longevity and optimal performance of the Fan-Tastic Vent:
The manual emphasizes the importance of following safety instructions, including taking precautions when working on the RV roof and ensuring proper electrical connections (12 VDC only, filtered DC current). It also advises against leaving the vent lid open and unattended for extended periods or using the product in inclement weather to prevent water damage.
