What is an RV Vent Fan & Why Do You Need One?

An RV vent fan is essentially a fan in your RV ceiling with a vent that cranks up or lifts up automatically. It is essential to keeping the air circulating in your motorhome, preventing moisture build up, reducing the temperature inside your coach, and removing odors.

Thanks to its internal fan, an RV vent fan is much more effective than simply opening the windows. Plus as it is situated up on your RV roof, you are less likely to get the dusty or polluted air that you can get further down at window-level, especially if you’re on the road. RV vent fans can even be left open while you’re away from your RV without presenting a security risk – unlike windows.

They are also essential for ensuring that any pets in your trailer have a good supply of fresh air and won’t overheat.

Buyer’s Guide to Buying the Best RV Vent Fan

To help you find the best RV vent fan for your motorhome, you’ll want to consider the following essential features.

Price

The price of an RV vent fan varies considerably depending upon its features and construction.

If you are looking for a budget model, you can find several units that will get the job done, starting from around $40. However, these types of RV vent fans tend to be less reliable, have fewer features, and may be much less durable than higher priced versions.

Spend a bit more and you can pick up a good quality RV vent fan for around $80-$150. These models are often reversible and some may feature remote controls, variable speeds, and even built-in thermostats.

Models priced over $150 are designed to last even longer and may have more advanced features and programmable controls to make using your vent fan an even easier experience.

CFM Rating

The CFM rating tells you how much air your fan can move, measured in cubic feet per minute (CFM). The higher this figure, the faster your vent fan will be able to pull out humidity and odors from your rig.

Note that manufacturers will usually give you the maximum CFM rating for your vent fan on the highest speed, this rating will obviously be lower at lower speeds.

Single Direction or Bi-Direction Airflow

Cheaper RV vent fans tend to only offer single direction airflow, venting your coach air to the exterior. Most of today’s models provide bi-directional airflow, allowing you to select whether you want to pull in air from outside or to vent your RV air outwards.

For example, if it is cooler outside and you want to reduce the temperature inside your rig, you may want to switch your vent to suck cold air in. On the other hand, if you have a moisture build up, for example after showering or while cooking, you’re going to want to switch your vent fan to expel your damp coach air out of your RV.

Remote Control

Remote controls can be handy to activate or alter the settings of your RV vent fan. They are very useful in coaches with high ceilings where you may struggle to press the buttons on the unit itself. They are also a great choice if your vent fan is over your bed, meaning you won’t have to take off your shoes everytime you want to adjust your fan settings.

However, bear in mind that most RV vent fan remotes need to be used within a direct line of your fan, some even need to be directly under it, making it almost impossible to regulate your fan from the other end of your RV, for example. So, while a remote control is nice to have, they do have their limits.

Speed Control

Ideally, unless you are going for the cheapest model around, you’ll want at least three fan speeds.

Lower speeds allow you to constantly and quietly renew the air in your RV without a noticeable breeze, whereas higher speeds are useful for faster cooling or moisture and odor-elimination.

Some models have 10 or more speeds. While some users find a large choice of speeds useful, others stick to the same one or two speeds regardless. This really comes down to your personal preferences and needs.

Rain Sensor

Rain sensors cause your roof vent to close up if it starts to rain. This can be really handy if you are leaving your RV vented and unattended, saving your interior from getting wet.

However, if you have pets, we recommend choosing a model with a vent cover that allows for venting even during wet periods, without your interior getting dripped on.

Why? Well, as we all know, RVs can get very hot and as with all small, enclosed spaces, there is a limited amount of oxygen available without cranking open a vent or window. If you leave your pets unattended in your RV while you go out, you’ll undoubtedly start up the vent fan to keep them comfortable and safe.

However, with a rain sensor, should it start to rain, your air vent will close and your pets could be without fresh, cool air for several hours or longer. This could quickly deteriorate into a life threatening situation for them, so always remember to make sure they will have an unobstructed source of fresh air and install a temperature monitoring system (TPS) that will notify you if the temperature rises dangerously while you’re out.

Power and Energy Draw

RV vent fans are designed to run off your battery power, so even when you’re off-grid and can’t fire up your AC unit, you can still use your fan. As they are designed to draw from your 12V DC battery power, RV vent fans have very low power requirements, drawing just one or two Amps during normal usage.

Fan Size

Your RV fan size is dictated by the standard 14” by 14” roof opening for the entire vent fan unit. Fans are normally around 10” to 12” to ensure that you get maximum efficiency and airflow, as well as compatibility with your standard roof opening.

Height of Your RV Ceiling

If your RV has high ceilings, you’ll struggle to reach the buttons on your unit and will need to look for a model with a remote control. Also, bear in mind that rigs with higher ceilings are going to have a larger cubic area of air, so you would be better off with a RV fan vent that has a high CFM rating to move that extra air out more effectively.

Fan Noise

Some of us are much more sensitive to noise than others and some fans make a lot more noise than others. If noise is likely to be an issue for you, you’ll want to look out for models with more speeds, so you can use the lower settings that tend to make less noise.

With time, people tend to get used to the noise put out by their fan and it eventually becomes part of the white noise that they are accustomed to. However, if your RV vent fan is located above your sleeping area, you may want to specifically focus on looking for an extra-quiet model.

Ease of Installation

Replacing an old fan with a new one is generally very easy, except for removing the old sealant which can be a bit of a struggle.

As RV vent fans are designed to fit into the same sized openings, it is generally just a case of attaching the 12V wire, screwing your new unit into place, sealing, and attaching the garnish.

Fitting a new RV vent fan as opposed to replacing one can be a little tricker as you will need to cut a hole in your roof and source a 12V power supply, usually by running a wire from the nearest light.

While installing an RV vent fan is pretty simple, if you are not simply upgrading and don’t feel confident cutting into your rig’s roof, getting your new RV vent fan installed by a professional is the best way to go.

Rain Shield and Dome

To keep your RV vent fan on in the rain or when you’re out, you’ll want to look for models with a rain shield.

This will allow your fan to circulate the air, without rain getting inside your coach. If your RV vent fan doesn’t come with a rain shield as standard, you should be able to purchase a dome cover separately.

A rain shield is not only essential if you have pets, it also allows you to leave your RV vented and unattended without worrying about any potential water damage. A rain shield will allow you to continue to vent your RV in all weathers.

Manual or Automatic Lid Opening

A lot of RV vent fans now feature automatic lid opening mechanisms. If you are using your RV vent fan with a remote control this makes sense, allowing you to start up your fan without having to get too close up.

On the other hand, if you are using the buttons on your fan itself, it doesn’t take that much effort to manually crank it open. In any case, you’ll want to have the option to manually open your vent lid in case of a power failure.

Recommended Accessory – Roof Vent Fan Insulators

Whether you’re upgrading your RV vent fan or installing a new one, you’ll want to pick up a roof vent insulator. Roof vent insulators are essential to keeping your rig cool in hot summer weather. They are highly effective at preventing heat from entering your coach via your vent fan.

Our favorite model, the Camco RV Vent Insulator fits all standard 14” openings. Thanks to its highly reflective surface it helps to block and reflect the sun’s rays, while the insulative thick foam layer prevents heat transfer to your RV. It’s also available at a good price and like all Camco products, it’s a really useful, well-designed RV accessory.

RV Vent Fan Vs an RV AC

While an RV vent fan isn’t going to be able to completely replace your RV AC, there are plenty of scenarios when it makes an all round better choice.

Off-grid – when you’re not hooked up to shore power, you’ll really struggle to run your AC, especially for any meaningful length of time. With its low power draw directly from your 12V house batteries, you can use your vent fan for long periods.

Odors – whether it’s your pets creating a stink, burnt toast, or musty odors, your RV vent fan is the best way to get rid of foul smelling air in your RV. Your AC unit will simply circulate the smell around your coach, whereas your vent fan releases it outdoors.

Cool outside but hot inside – when you’re too hot inside your RV, but it’s nice and cool outside, it makes sense to switch on your vent fan rather than your AC.

Fresh air – living and breathing in a small enclosed environment creates a lot of moisture build up and depletes oxygen levels. Cracking your vent fan open occasionally gives you fresh oxygenated air and releases moisture to the outdoors reducing relative humidity levels. Your AC relies on a closed circuit to effectively chill your coach air, meaning no fresh air.

About Karan Riley

I am the owner and main contributor to RV4Campers. I first got bit by the RVing bug when I joined a friend who was into Van Life for weekend getaways. It became apparent very quickly that this was a style of life I enjoyed and wanted more of, so it wasn't long before I had my own travel trailer. I didn't have a lot of money to throw around back then so I did lots of research into all the gear and gadgets. And this is how my RV passion exploded, I've now spent countless hours playing around with many different bits of kit and reading user manuals. And it's this wealth of knowledge I bring to RV4Campers.
