RV Roof Vent Fan

Best RV Roof Vent Fan Review & Buying Guide

Updated October 2, 2022

- By Tim Harris

The RV roof vent fan moves the airflow through the camper. RV roof vent fans are extremely helpful on days when it’s hot and the air is still. You can’t run your Air Conditioner in your RV until you hook it up to the shore power because the AC requires a lot of energy. So the only better way to move air in your RV when the air conditioner isn’t running is with a vent fan.

To deal with the heat and odors in your RV, you need a good-quality roof vent fan that works. The roof vent fan on your RV moves the air around. This unit needs to be changed out every so often. An RV vent fan comes in a standard size, so it’s easy to find one that will fit your RV.

Picking out the best fan can be challenging. In this article, we’ll talk about some of the best RV roof vent fans that will make your research easier.

Importance of an RV Roof Vent Fan

RV roof fans are one of the best ways to keep smells, moisture, and heat from getting into your RV. You can use this fan instead of the air conditioner in your RV. This roof vent fan is helpful in colder climates because it keeps the RV from getting wet.

In the small space of an RV, condensation can cause trouble. After you turn on your RV fan, keeping the window open will help the air move through the small space of your RV. If your camper roof vent didn’t come with an RV fan, you should replace it yourself to get all of the benefits.

But don’t buy a cheap RV vent fan from a brand you’ve never heard of. The cheap fans can’t get rid of the moisture because they don’t have enough power.

Considering Factors of Fan Power

Fans on the RV roof do not need a lot of amps to work. Your 12V RV batteries can run these vent fans just fine. At full speed, the most powerful fan only uses 3 to 4 amps. Also, these vent fans only need 1 amp of power to run at low power settings.

The RV vent fan with the most power pulls in a lot of air. But the amount of air pulled depends on how big the rig is. Some rigs can also have more than two vent fans. Surprisingly, this vent fan does a good job of moving air around in the rig.

Considering Factors of an RV Roof Vent Fan

When you are looking for an RV roof vent fan, you should consider the following factors:

Vent Fan Options

Different vent fan options are available, including the following:

  • Remote control. 
  • For using the fan in inclement weather, the vent fan comes with rain covers.
  • Different speeds.
  • For air pulling or pushing, the vent fan comes with reversible blade rotation.

RV Roof Vent Size

Most roof vents on campers or RVs are 14 inches by 14 inches. If you need to replace the vent fan in your RV, measure the hole to get an idea of the size of the vent. Take the measurements and make sure the new fan is the same size as the old one. You can also cut out a bigger hole if the roof vent fan is larger than the one you are replacing.

RV Ceiling’s Height

Make sure you can easily reach the ceiling of your RV so you can open the trailer vent fan by hand. If it’s hard to get to the trailer fan, you can use a remote to operate your roof vent fan.

Noise Factor

Another important thing to think about is how loud the roof vent fan will be, which will depend on how much time you will spend on it. Some people only use the RV twice a year, while others live in it all the time so the noise of the fan will be an important factor to consider.

So, before you buy a fan, you should think about how loud it is. Some fans are louder than the others that are available on the market. If you choose a vent fan that makes a lot of noise, you might have to get a new one. Some roof vent fans that make a lot of noise don’t move or circulate much air inside the RV.

RV Roof Vent Covers

If you buy the best roof fan for your RV, it should come with a separate vent cover. If you leave the roof vent on your RV open when it’s raining, you should have a backup vent cover to keep the water out. But you don’t need these RV roof vent covers if you buy a vent fan with a rain sensor.

There are some downsides to these vent covers, like the fact that you have to pay an extra $50 to buy them and most covers for RV roof vents are bulky, big, and unsightly. The RV vent covers can cast also shadows in your RV.
