We ranked seven roof fans sold on Amazon.com using only the specs on each listing. We have not installed them side by side on a roof. When a listing leaves out a number, such as power draw or noise, we say so. Airflow is shown in m³/h in the tables; divide by 1.7 for cfm.

The 7 best RV roof vent fans, reviewed
1. Maxxair Maxxfan Plus 00-04550K 10-Speed Roof Vent Fan
1,529 m³/h · 10 speeds · reversible
9/10 · VanThermia scoreThe Maxxfan Plus 00-04550K has the best balance of features in this list. Its listing declares more than 900 cfm, 10 speeds, intake and exhaust airflow and a thermostat that adjusts fan speed to hold your chosen temperature.
The key feature is the lid. It opens electrically, and the fan can run with the lid fully closed, so it keeps venting through rain. The warranty is 2 years, plus a lifetime warranty on the lid. The gaps are in the data: no wattage, noise or weight. The size on its listing is the blade diameter, not the roof opening, so confirm the fit for your cut-out.
Pros
- Over 900 cfm with 10 speeds, per the listing
- Intake and exhaust modes plus a thermostat
- Runs with the lid closed; 2-year warranty and lifetime lid warranty
Cons
- No power draw, noise or weight on the listing
- Keypad only: no remote mentioned
- Best for
- Full-time van and RV living in all weather
- Skip it if
- Anyone who wants to control the fan from bed with a remote

2. Kohree KR5312 14" RV Roof Vent Fan, Rain Sensor
1,587 m³/h · 10 speeds · reversible
9/10 · VanThermia scoreOn paper, the KR5312 is the most complete fan here. It declares 934 cfm, 10 speeds, reversible flow, a rain sensor that shuts the lid, a remote and a temperature sensor that starts the fan when the cabin warms up. It fits the standard 14 × 14 in (35.6 × 35.6 cm) opening and weighs 5.0 kg (about 11 lb).
Its declared draw is only 25 W on high. At 12 V, that is about 2.1 A (25 ÷ 12). The downsides: no warranty on the listing and a maximum of 50 dB. The listing also warns against opening the lid in strong wind.
Pros
- About 934 cfm (1,587 m³/h) on 25 W, per the listing
- Rain sensor closes the lid automatically; remote control
- 10 speeds, reversible, thermostat, fits 14 × 14 in
Cons
- No warranty stated
- Up to 50 dB, the loudest published figure here
- Best for
- Vans and RVs on solar and battery that want automation

3. 2012 F36AR 14x14 RV Roof Vent Fan, Remote & Rain Sensor
1,145 m³/h · 4 speeds · reversible
8.5/10 · VanThermia scoreThe F36AR, sold under the brand name 2012, is built around quiet running. Its listing declares 25 dB, a rain sensor that closes the lid, a remote, reversible flow and 4 speeds. It fits the standard 14 × 14 in opening and has a 2-year warranty.
Airflow is lower than the leaders: 1,145 m³/h, about 674 cfm. It also declares the highest draw here, 40 W, about 3.3 A at 12 V. The listing does not say at which speed the fan reaches 25 dB, so do not assume it holds at full speed.
Pros
- 25 dB declared, the lowest here
- Rain sensor, remote and reversible flow
- 2-year warranty; fits 14 × 14 in openings
Cons
- About 674 cfm, the lowest published airflow
- 40 W, the highest published draw
- Best for
- Light sleepers and bedroom ventilation
- Skip it if

4. RVLOVENT 14" 10-Speed Reversible RV Roof Fan, Manual
1,699 m³/h · 10 speeds · reversible
7/10 · VanThermia scoreThe RVLOVENT fan keeps things simple: a manual crank lid, 10 speeds and reversible flow, with no remote. It fits the 14 × 14 in opening and declares 45 dB and 24 W.
Its bullets claim 1,000 cfm (1,699 m³/h), the highest figure here. Treat it with caution: the spec table on the same listing gives different speeds, airflow and wattage, and 1,000 cfm on 24 W cannot be checked. Without rain protection, you must close the lid when it rains.
Pros
- About 1,000 cfm claimed, the highest here
- 10 speeds and reversible flow
- 24 W and 45 dB declared
Cons
- Manual lid, no rain protection and no remote
- Spec table contradicts the bullets on speeds, airflow and power
- Best for
- Owners who prefer a manual lid and simple controls
- Skip it if
- Anyone who leaves the vent open while away

5. Maxxair Maxxfan Deluxe 00-05301K Roof Vent Fan
1,529 m³/h · 4 speeds
6.5/10 · VanThermia scoreThe Maxxfan Deluxe 00-05301K shares the Maxxfan’s 900 cfm rating and a built-in rain shield, so it can vent in the rain. It fits a 14 × 14 in opening and weighs 7.1 kg (about 15.7 lb).
It is exhaust only, with 4 speeds, a manual lid and controls on the ceiling unit. That is fine for pulling out steam and stale air, but it cannot draw cool air in. The wattage in its spec table simply repeats the cfm number, so we ignore it, and no warranty is stated.
Pros
- About 900 cfm, per the listing
- Built-in rain shield
- Fits the 14 × 14 in opening
Cons
- Exhaust only: it cannot pull air in
- 4 speeds, manual lid and no warranty stated
- Best for
- Kitchen and bathroom venting in wet climates
- Skip it if
- Cooling the rig with outside air on hot nights

6. RVMATE 14x14 12V RV Roof Vent Fan with Remote
3 speeds · reversible
6.5/10 · VanThermia scoreThe RVMATE fan declares just 5 W, about 0.4 A at 12 V, with reversible flow and a remote. It fits standard 14 × 14 in openings, weighs 2.6 kg (about 5.7 lb) and comes with sealant and hand cranks.
The listing gives no airflow figure, so you cannot compare it with the others. The 5 W figure comes from the spec table and is not confirmed elsewhere. It has 3 speeds and no rain sensor or rain shield.
Pros
- 5 W declared, the lowest here
- Reversible flow with a remote
- Fits 14 × 14 in; 2.6 kg (about 5.7 lb)
Cons
- No airflow figure
- 3 speeds and no rain protection
- Best for
- Small battery banks and occasional venting
- Skip it if
- Heavy condensation or hot climates

7. Maxxair Maxxfan Plus 00-04002K 4-Speed Thermostat Fan
4 speeds · reversible
6.5/10 · VanThermia scoreThe 00-04002K is a 4-speed Maxxfan Plus with a thermostat and intake and exhaust modes, according to its truncated title. Almost everything else is missing from the listing.
There is no airflow, power, noise, opening size or warranty, and the weight in the spec table is not credible for a Maxxfan. Unless you can confirm the specs elsewhere, the 00-04550K above is the safer Maxxfan choice.
Pros
- Maxxfan Plus with 4 speeds
- Intake and exhaust
- Thermostat, per the title
Cons
- Almost empty listing: no airflow, power or warranty
- Weight in the spec table is implausible
- Best for
- Buyers who already know this Maxxfan model
- Skip it if
- Anyone comparing specs

How do I choose an RV roof vent fan?
Check the opening size, rain protection, reversible flow, airflow and power draw, in that order. The fan must fit your cut-out, usually 14 × 14 in. Rain protection lets it run when you are away or asleep. Reversible flow adds cooling on summer nights. Airflow sets how fast steam clears, and power draw decides how long you can run it on battery.
Power draw matters most off-grid. Here is what the four fans that publish a wattage would use over an 8-hour night at 12 V, using Ah = W × h ÷ V. The listings do not say at which speed the figure applies, so treat it as a ceiling:
| Fan | Declared power | Amps at 12 V | Ah over 8 hours |
|---|---|---|---|
| RVMATE 14-12V | 5 W | about 0.4 A | about 3 Ah |
| RVLOVENT 10-speed | 24 W | 2 A | 16 Ah |
| Kohree KR5312 | 25 W | about 2.1 A | about 17 Ah |
| 2012 F36AR | 40 W | about 3.3 A | about 27 Ah |
A roof fan is the first line of defense against damp. Our camper condensation guide shows how to combine it with insulation, dry heat and a dehumidifier. To budget the draw, try the RV power calculator.
What are the most common mistakes?
The most common mistake is buying a fan without rain protection and then closing it every time it rains. Here are six to avoid:
- Confusing blade size with opening size. Some listings print the blade diameter; what matters is the cut-out, usually 14 × 14 in.
- Skipping rain protection. Without a rain shield, a closed-lid mode or a rain sensor, the vent must stay shut in wet weather, when condensation is worst.
- Buying exhaust only when you want cooling. The Maxxfan Deluxe 00-05301K cannot pull cool air in.
- Trusting airflow claims that do not match the power. When the spec table and the bullets disagree, as on the RVLOVENT listing, treat the figures as unconfirmed.
- Ignoring the draw. 40 W for 10 hours is about 33 Ah at 12 V (40 × 10 ÷ 12).
- Expecting a fan to replace air conditioning. A fan moves outside air; it cannot cool below outside temperature. See the best RV rooftop air conditioners.
Which one should I pick by cost level?
Branded, automated fans sit at the top, simple manual fans at the entry level. We do not list prices because they change daily; check the current listing.
- Entry: RVMATE 14-12V and RVLOVENT 10-speed. The RVMATE draws least; the RVLOVENT claims the most airflow but has no rain protection.
- Mid: Kohree KR5312 and 2012 F36AR. Both have a rain sensor and a remote; the Kohree moves more air, the 2012 is quieter.
- High: Maxxfan Plus 00-04550K, Maxxfan Deluxe 00-05301K and Maxxfan Plus 00-04002K. The 00-04550K is the one to buy.

What is our verdict?
Frequently asked questions
What is the best roof vent fan for a camper van?
For most vans and RVs, the Maxxfan Plus 00-04550K. Its listing declares over 900 cfm, 10 speeds, intake and exhaust modes, a thermostat and a lid that lets it run in the rain, with a 2-year warranty and a lifetime lid warranty.
What size roof opening do RV vent fans need?
Most fit the standard 14 × 14 in (35.6 × 35.6 cm) RV roof opening. Five of the seven here state it on the listing. The Maxxfan Plus 00-04550K listing gives only its blade size, not the opening, so check the fit before ordering.
How much battery does a roof vent fan use?
Amp-hours = watts × hours ÷ volts. The Kohree KR5312 declares 25 W on high: about 2.1 A at 12 V, or around 17 Ah over 8 hours. Lower speeds use less. The Maxxfan Plus listing does not publish its draw.
Do I need a reversible roof fan?
It helps. Exhaust clears steam and stale air; intake pulls cooler outside air in on summer nights. Six of the seven fans here are reversible; the Maxxfan Deluxe 00-05301K is exhaust only.
Can a roof vent fan run in the rain?
Only with a rain shield or a lid that runs closed, like the Maxxfan models, or a rain sensor that shuts the lid, like the Kohree KR5312 and 2012 F36AR. Without one, you must close the vent when it rains.
