How to choose
Good to know
What size vent fan do I need for my RV?
Most RVs have a standard 14×14 inch roof opening. However, some smaller trailers and truck campers may have 9×9 or 12×12 openings. Measure your existing vent opening before purchasing. Compact fans are designed to fit these smaller sizes.
How many CFM do I need for good ventilation?
CFM stands for cubic feet per minute and measures airflow. For an average size RV (15-25 feet), a fan with 500-900 CFM is sufficient. Larger RVs or those in hot climates benefit from higher CFM. Remember that higher CFM fans may be noisier.
Are these fans truly waterproof?
Yes, these fans are designed to be waterproof when the lid is closed. They have sealed lids and gaskets that prevent water from entering. Some models feature rain sensors that automatically close the lid when moisture is detected. Always ensure the fan is closed when not in use or during rain.
Can I install a vent fan myself?
Many RV owners install vent fans themselves. The process involves removing the old fan, applying sealant, and securing the new fan. Basic electrical wiring may be required. If you are not comfortable with DIY, consider professional installation.
Do these fans have reversible airflow?
Some models offer reversible airflow, allowing you to either exhaust air out or intake fresh air. This is useful for ventilation and cooling. Check the product specifications to see if the fan has this feature.
What is the benefit of a remote control?
Remote controls allow you to operate the fan without reaching up to the ceiling. This is especially convenient when the fan is installed in a high spot or when you want to adjust settings while lying down. Some remotes include thermostats and timers.
Will a vent fan drain my RV battery?
Vent fans are 12V DC and draw low power, typically around 1-3 amps. Running the fan for long periods can drain your battery if you are not connected to shore power or have solar. Most owners use them intermittently or while driving.
How do I clean my vent fan?
Turn off the fan and remove any debris from the screen or blades. Use a soft cloth or brush with mild soap and water. Avoid using harsh chemicals that may damage the plastic. Dry thoroughly before using again.
The bottom line
For most RVers, the Maxxair MaxxFan 700K is the best choice due to its reliable rain sensor and remote control, offering convenience and peace of mind. If you are on a tight budget, the CAMCO Vortex provides excellent value without compromising on essential features. If you want smart control, consider the Fans 12V with app connectivity. Ultimately, prioritize your must-have features and select the fan that aligns with your travel lifestyle.
