The Velit V3 with Ventilation is the updated replacement for the Velit 3000R, built for van and RV owners who want rooftop DC air conditioning with added fresh air movement in a smaller package. It keeps comparable cooling power while upgrading the platform with a smaller footprint, dual fans, and a built-in exhaust fan.
Traditional rooftop AC systems only recirculate cabin air. The Velit V3 is designed differently by combining powerful rooftop air conditioning with integrated fresh-air exhaust ventilation. This helps move stale cabin air out while the AC cools the cabin, giving you one system, one roof opening, and more room for solar or other roof-mounted gear.
With up to 350 CFM of airflow, the built-in exhaust fan can help reduce heat buildup, stale air, odors, and humidity. The 12V model is 10,000 BTU, and the 48V model is 12,000 BTU. Both versions use R32 refrigerant and are designed around a standard 14 in x 14 in roof opening.
The built-in exhaust fan is a compact supplemental fan. It is not a replacement for a larger bi-directional roof fan such as a MaxxFan, Airplus, or Probreeze. It works best alongside a larger roof fan, floor vent, or other ventilation setup.
The built-in fan adds useful fresh air movement, but it should be treated as a compact supplementary fan rather than a full-size roof fan replacement.
Yes. The Velit V3 with Ventilation replaces the Velit 3000R with comparable cooling power, a smaller footprint, dual fans, and built-in supplemental ventilation.
12V and 48V variants. Choose the version that matches your electrical system.
The 12V model is listed at 10,000 BTU, and the 48V model is listed at 12,000 BTU.
No. The built-in fan is a compact supplemental ventilation fan. It is useful for added airflow, but it is not a direct replacement for a larger 9 in or larger roof fan.
It can be noticeable above 50 percent speed. Lower fan speeds are recommended when quieter operation is more important than maximum airflow.
The V3 is designed around a standard 14 in x 14 in roof opening with plus or minus 1/2 in tolerance.
Sealant is not listed as an included item. For van installs or other uneven roof surfaces, sealant should be purchased separately. Flat RV roof installations may not require additional sealant depending on the install surface.
The manual lists the V3 air conditioner, air distribution box assembly, mounting bracket, sealing gasket, return air filter, leveling blocks, ducts, wiring harness, remote, display panel, user manual, cutting template, hardware kit, zip ties, and cable tie mounts.
The manual recommends 75A+ supply current for the 12V model and 30A+ supply current for the 48V model.

Great product. Used daily in my build— ac fan solar….
Great products, responsive team!
What can I say? Orion takes great care of their customers. They went out of their way to help me and I appreciate it. I also found out too late that they sell 8020 Roll in nuts. I use the 10 series for my build. The nice thing about Orion‘s 10 series rolling nuts is they have a register on top of the nut that keeps it from twisting in the extrusion. I wish I would’ve known this when I bought all my hardware. I would’ve definitely bought this product from Orion. Check them out.
Kaiya provided wonderful support for a troublesome panel struggling during a second year of operation -- I could not be more pleased to have chosen Orion for my solar! The Stealth rack & awning are quite sweet as well :). Thanks Orion!
So far so good. Installed on my Sportsmobile converted dodge promaster. Waiting for the rain to see how it does in wet conditions. Once I figured out how to install it was VERY easy. Only ask would be more details on initial installation process since I wasn't sure exactly where to place the track. Once I got it installed and put the fly in the track it was so easy. Excited for how this will work on my pop-top van.
Love it! I researched a lot before deciding on Orion. I just think their design out looks all the others. This is functional, solid, and easy install. Customer service was excellent. They answered all my questions. I didn’t build my van, I bought it already done. Solar panel and all, I was able to move the solar panel to a better location using their solar panel brackets, I’ll easily add some decking following their recommendations of what decking product to use, and be able to store items I don’t want in the van. Love supporting a local Oregon business. Would recommend them to everyone. Oh and I got the rack with the lights. Totally recommend. The install was perfect and they really light up the night!
Thank you, Krysta! It’s so great to see everything come together on your van. We’re glad we could help you get the solar placement dialed in and plan for decking and extra storage. And thank you for sharing the videos showing off the rear scene lights and flush solar brackets; they’re a huge help to others planning their setups! We really appreciate your recommendation and support for a local Oregon business. Enjoy your adventures!
