Your motorhome can be many things: home base during much-needed vacations, a guest bedroom, a mobile office or even a permanent dwelling. But, when the summer heat settles in and the sun shows no mercy, making your motorhome cool is often difficult. Of course, flipping the switch on the air conditioner (sometimes two, depending on coach size) is usually a quick solution, but that requires 120-volt AC power or an AC generator. So, if you’re not hooked up to shorepower, you plan on being away from the coach for most of the day and don’t want to run your genset to burn fuel, it becomes even more important to have a roof vent/fan that can move a considerable amount of air without running down the house batteries.
Opening a vent and/or running the fan won’t exactly help the climate inside reach frigid temperatures, but a well-placed fan and a few open windows to create a cross-breeze can keep the temps at a manageable — and hospitable — level, for you and for any four-legged family members that may accompany you. Sometimes, that’s all it takes to keep you at the campsite rather than packing up and heading for cooler environs.
There are many types of roof fans, with varying degrees of functionality. Some are straightforward air movers, while others include high-tech systems with rain sensors that will shut off and close down when the clouds roll in. However, they all fit basically the same template: they’re low-battery-draw units that will fit into a standard 14-inch roof opening; they can often be found in the bathroom and the galley, and sometimes over the living area; and they’re downright life savers when it comes to the sweltering dog days of summer.
Following are some top fans from the “Big Three” of the fan segment, and with a little follow-up research on the phone, at your local Camping World store or even at www.motorhomemagazine.com, we’re sure you can find the perfect model to fit your needs and your budget.
Perhaps the most recognizable name in the roof-fan segment, Fan-Tastic Vents offers a wide variety of fans designed to keep things cool. The 6600R High Powered Vent Fan is Fan-Tastic’s top-of-the-line model and provides 14 speeds and up to 920 cubic-feet-per-minute air circulation. The radio frequency (RF) handheld remote allows users to activate the fan and raise the dome by pressing the mode pad. The unit’s automatic mode allows users to select a comfort setting, and the blades will automatically turn on, off, increase or decrease speed to maintain the temperature choice. The 6600R vent is equipped with a reversible airflow switch and a rain sensor, which closes the dome and turns off the fan blade when the sensor becomes wet (the dome reopens when the sensor dries). A rain sensor shut off switch and a backup manual dome open/close knob are also provided. MSRP starts at $258.99. Not ready to lay down that much cash? Owners of standard Fan-Tastic vents can upgrade their existing models to a 6600R using a kit ($155-$185).
Other Fan-Tastic models offer the same level of performance, with a decrease in cost based on the amount of included features. The 6000RBTA ($216.99-$230.99) features three fan blade speeds, a reverse switch, a built-in thermostat, automatic dome open/close switch and a rain sensor.
The 5000RBT ($169.99-$180.99) offers the same functions, less the auto lifting dome and the rain sensor, while the 400R is a three-speed fan with a manual-lifting knob ($149.99-$155.99).
Fan-Tastic also offers the portable Endless Breeze, a high-volume, 12-volt DC fan operating with a three-speed, 12-inch blade. Standing only 14 inches tall on retractable legs, it travels and stores easily and weighs less than 5 pounds. The Endless Breeze offers air movement of up to 900 CFM, and can be powered by any 12-volt DC power source. Plus, the Endless Breeze is equipped with an innovative pet-friendly feature, the Swing-Out Hanger Arm, which allows easy attachment of the fan to the side or front of your pet crate. MSRP: $54.99-$67.99.
