RV Vent Fan Replacement – Heng’s Vortex II Review & Installation Guide

It was time for our RV vent fan to be replaced. For about a month, we could tell the old fan was on its last leg. It would turn on, but it sounded weak and got weaker as time went on. Eventually, we knew it needed to be replaced before it quit completely.

Why We Chose Heng’s Vortex II Fan

When traveling from Yellowstone to Texas, I didn’t have the time or place to replace the fan right away. That gave me some research time to figure out the best option: should I just replace the motor, or upgrade to a better fan?

After digging around, I came across the Heng’s Vortex II Vent Fan — a direct replacement for most factory fans (Ventline, Jensen, Elixir, and Heng’s). What stood out is that it installs from inside the RV, meaning you don’t have to disturb the rooftop seal and risk future leaks.

At Camping World, the fan was priced near $190, but I found it on Amazon for around $100. That was a no-brainer. Once we got settled for a 28-day stay in Austin, Texas, I ordered it, and it arrived two days later.

Heng’s Vortex II Vent Fan – Features

• Multi-speed quiet operation (3 forward speeds, 2 reverse speeds)
• 9″ blades for efficient, quiet airflow
• Over 300% more airflow than standard roof vents
• Universal fit for Elixir, Ventline, Jensen, and Heng’s powered vents
• Quick installation with just a Phillips screwdriver
• Installs from inside — no need to disturb rooftop seal

The one small concern I had was the exposed circuit board on top of the unit. It seemed like it could get wet and short out, but after long-term use, we haven’t had any problems.

Installation Guide

Installation took only about 15 minutes and required minimal tools.

Steps:

3. Remove the screws that hold the shroud in place and remove the shroud.

4. Disconnect the wires that run to the fan motor.

5. Drill out the rivets that hold the fan motor bracket in place and remove the bracket and fan motor.

6. On the new fan assembly, you need to figure out which of the two points for the vent control knob you need to use for your system. You may need to move the mechanism from where it is installed to the other location, depending on how your vent is set up.

7. Attach the wires to the new fan.

Before & After – Airflow Difference

The original fan in our motorhome was a small 6″ blade — typical RV “builder-grade” parts. The Vortex II’s 9″ blade with multiple speeds made a huge improvement in airflow and noise levels. It’s a noticeable comfort upgrade, especially when cooking or cooling down the RV.

Alternatives to Heng’s Vortex II

While we’re happy with the Vortex II, here are other popular RV vent fan upgrades worth considering:

• Maxxair 6200K Vent Fan – Remote control, rain cover, multiple speeds.
• Fan-Tastic Vent 801250 3-Speed Fan – Reliable and quiet, though often pricier.

If you want a budget-friendly, direct replacement without cutting into your roof, the Heng’s Vortex II is the sweet spot.

Conclusion

If your RV’s old vent fan has died — or you’re simply tired of weak airflow — the Heng’s Vortex II is an excellent choice. It’s affordable, efficient, and installs in minutes without disturbing the rooftop seal.
