Overview

The Le Mans Low Profile 12V Fan is a reversible roof ventilator for vehicle builds that need controlled intake and exhaust made in the Netherlands. Its standout benefit is how low profile it is; the exterior cowl sits only 2.52 inches above the roof, helping you preserve roof space for racks, solar, or decking (compared to 9.3" inches with a Maxxair Deluxe and 3.93" inches with a Maxxair Dome) The Lemans fan is designed for both supply and exhaust airflow. Direction is controlled by wiring polarity (via an included 3-way switch), and airflow intensity is controlled with a variable speed dial (included).

Important Info

This is not a plug and play kit. It ships as components and requires basic assembly and wiring by the installer. Please review the installation instructions before purchasing. Wiring harness and roof adapter are not included. A roof adapter is required for ProMaster installs, or any roof that is not flat at the cutout area.

Intake or Exhaust

Reversible airflow supports both bringing fresh air in and exhausting air out, depending on wiring direction. Interior closure can be either manually or electrically closed. White vents are included in this kit. These vents are different from typical RV vents in that the air closure is on the inside. The unique design of the cowl keeps moisture out. A black exterior cowl is included in this kit.

We just installed a Stealth+ on our 2026 High Roof Transit. So glad to have an option that works with the new shark fin antenna location in the '26 model year. Another advantage of the Stealth+ rack is that its usable area is wider and longer than other racks. That, along with the Orion team's help in providing CAD layouts was SUPER helpful in thinking through our roof layout and how to fit 600W of solar along with a vent fan and Starlink Mini.

Thank you for your feedback. We are delighted to hear that the Stealth+ was a perfect fit for your 2026 High Roof Transit, especially with the new shark fin antenna location. We take pride in providing solutions that cater to the latest updates. Thank you for choosing Orion and happy travels!

Great rack, lightweight, easy to assemble, solid, no added noise, fits (2) 200w Renogy ShadowFlux panels flush mounted with room to spare, no added noise, and looks great. Highly recommend.

Looks great! See you on the road!

Setup was super easy. The ECOFLOW Gen 2 is basically plug-and-play, everything is clearly labeled. Also ORION has been super helpful with any questions along the way!

Thanks, AJ! Easy setup, clear labels, real support. Enjoy the system and the extra off-grid time.

The Comvolt 4200 (with AC/DC PDU and 7-inch screen) is a game-changer for any setup.
Super easy install—mostly plug-and-play with minimal wiring. No fuss, no extra components to hunt down.
It’s compact, portable, and incredibly versatile: works flawlessly off-grid in a van, car, shop, home, or anywhere else. Everything’s built right in, so you get clean power without the headache of piecing together a bunch of parts.
Expandable too if you need more juice later. Hands down one of the most convenient, reliable portable power stations out there.
Nice work, Comvolt team—I love it! Highly recommend.
Thank you Orion Van Gear
