Frequently asked questions
What is the difference between a vent fan and a roof vent?
A roof vent is simply an opening with a lid that can be opened manually. A vent fan has an electric motor that actively pulls air in or pushes it out, providing continuous ventilation even without wind.
Can I install a heavy-duty RV vent fan myself?
Yes, many RV owners install vent fans themselves. The process involves removing the old vent, cleaning the area, placing the new fan, and sealing it. If you are comfortable with basic tools and following instructions, it is a manageable DIY project.
Do all RV vent fans fit the same hole size?
Most standard RV vent fans fit a 14 x 14 inch rough opening. However, some high-velocity models may require a larger cutout. Always measure your existing opening and compare with the fan’s specifications before purchasing.
How do rain sensors work on vent fans?
Rain sensors detect moisture on the sensor located on the fan lid. When rain is detected, the sensor automatically closes the lid to prevent water from entering. This feature is useful if you leave the fan open while away.
Should I get a fan with a thermostat?
A thermostat allows the fan to automatically turn on or off based on the temperature inside the RV. This can help maintain a comfortable environment without manual adjustment. It’s a convenient feature for those who want automated climate control.
How much noise do heavy-duty vent fans make?
Noise levels vary. Fans with higher CFM ratings tend to be noisier, especially at maximum speed. Look for fans that advertise low sones or quiet operation. Many modern fans are designed to be surprisingly quiet even at high speeds.
Can I use a vent fan while driving?
Yes, most vent fans can be used while driving, but it’s important to ensure the fan is securely closed if you are not using it. Some fans have locks to keep the lid closed. Driving with the fan open can create drag and may not be safe.
What maintenance does an RV vent fan require?
Periodically clean the fan blades and the screen to prevent dust buildup. Check the sealant around the fan for cracks and reapply as needed. Lubricate the motor if the manufacturer recommends it. Most fans are low maintenance and last for years.
The bottom line
For most RV owners, the Maxxair Maxxfan Deluxe 7000K is the best all-around heavy-duty vent fan due to its balance of power, quietness, and smart features. If you are on a tight budget, the Camco 44217 offers dependable performance at a lower cost. For maximum airflow in a large rig, the Fans Plus 12V High Velocity fan is the top choice. Choose based on your specific RV size and budget, but any of these fans will improve your comfort significantly.
