Aero-Flo Vent Covers – Did You Know?

Better Airflow • Less Moisture • Longer Vent Life • Healthier RV Living

Aero-Flo Vent Covers are one of the most common upgrades installed on RVs — and for good reason. They allow you to leave a roof vent open in any weather, creating the airflow your RV needs to stay dry, comfortable, and healthy inside.

Most RV owners think Aero-Flo Vent Covers are simply for letting fresh air in during rain. They absolutely do that — but the real value comes from moisture control and temperature equalization inside the RV.

And that matters far more than most people realize.

Why RVs Need Ventilation

Unlike houses, RVs do not have attic ventilation or ridge vents to equalize temperature and moisture.

Every time you use your RV you introduce humidity inside the coach:

• Cooking
• Showering
• Sleeping and breathing overnight
• Wet gear or towels
• Temperature swings between day and night

When warm air inside the RV meets cold surfaces like windows, walls, and metal frames, condensation forms quickly.

You’ve probably seen it before:

• Fogged windows
• Water running down window frames
• Damp bedding
• Musty smells after storage

Over time, trapped moisture can lead to wood damage, mildew, odors, and premature aging of interior materials.

Aero-Flo Vent Covers help prevent that by allowing continuous airflow, even when the weather isn’t cooperating.

Why We Recommend Installing At Least One Aero-Flo Vent Cover

Many RV owners install Aero-Flo Vent Covers on multiple vents, but we strongly recommend at least one Aero-Flo Vent Cover on every RV.

Leaving one roof vent slightly open creates natural airflow through the coach and allows moisture to escape instead of getting trapped inside.

Why We Recommend Aero-Flo Vent Covers

✔ Reduces Window Sweating & Moisture Buildup
Allows warm, moist air to escape before it condenses on windows and interior surfaces.

✔ Leave Your Vent Open — Even in Rain or Snow
Aero-Flo Vent Covers shield the vent opening so air can flow while water stays out.

✔ 30% More Airflow Than Traditional Vent Covers
Aero-Flo Vent Covers move significantly more air, helping control humidity from cooking, showers, and overnight sleeping.

✔ Protects the Vent Lid from UV Damage
RV vent lids are exposed to constant sunlight and often become brittle over time. Aero-Flo Vent Covers protect the vent underneath and can dramatically extend its lifespan.

✔ Helps Maintain Airflow During Storage
One of the best ways to store an RV is with a roof vent slightly open. Aero-Flo Vent Covers allow airflow while keeping rain and snow out.

✔ Swing-Open Design for Easy Cleaning
Aero-Flo Vent Covers pivot open so you can easily access and clean the vent or fan.

✔ Installs Over Any Standard 14" × 14" Roof Vent
Hardware included.
