I install a lot of these for customers so I'm familiar with a lot of competitors and I'm super impressed with this heater! I was looking for a good heater that works with gasoline at a more affordable price. This is about 1/2 the price of some other brands with even more benefits. My favorite part is you can change the heater from gasoline to diesel or vice versa with an app! Other things I noticed that were impressive was the fuel filter is made of metal instead of plastic like every other brand has. The wire harness is easier and more DIY friendly. You don't need to crimp anything on the wires for it to work with the pump, super plug and play!
Thanks, Mason. Means a lot coming from a pro. Glad the app fuel switch, metal filter, and plug-and-play harness hit the mark. If you have install tips or photos, we’d love to share.
Can it be mounted under my van or does it have to be interior under a seat or cabinet?
The VELIT 4,000P - 14,000 BTU Camper Van Gas Air Heater can be installed both inside and outside your vehicle. When installing the heater outside, it's crucial to ensure the location is protected from rain and road debris. Additionally, maintain appropriate clearance in front of the air inlet and outlet to ensure proper airflow, keeping them free from obstructions.
For detailed installation instructions, please refer to the VELIT 4000P User Manual. This manual provides comprehensive guidance on both interior and exterior installations, including safety precautions and step-by-step procedures.
I just finished the install of the MaxxFan Deluxe, replacing a stock vent fan in our new Class C MH. Following the written (and online ‘how to’ videos) guidance, the install was straightforward. Most of the 3.5 hour job was spent cleaning off the old lap sealant in preparation for the new fan.
Fan works well in all functions. Thank you MaxxAir for a good product and thank you Orion for a great sales price!

So quiet. Easy to install. We received the wrong item from Orion (black interior control panel vs white) We contacted them via email and they immediately gave us several options to make it right. The fan works great and the customer service Orion provides is top notch.
Orion Van Gear offered the best pricing on my two new MaxxAir MaxxFan Deluxe fans and they arrive SO fast. The install on our our 5th wheel went exceptionally well. Thank you for the great experiences.
Hi Jamye, Sorry about the mix-up with the interior panel, but we're glad we could resolve it quickly. Thanks for your kind words and video! Its a slick fan!
Amazing product so far. Big pro is it's low draw on my jacket 600v. 4 days of use and the battery percentage is still at 70%. Convenience of the remote being able to be used from anywhere. The noise level is very low at 40-50% fan power. I chose this unit instead of maxxair because it matched my van aesthetically and it's very low profile that i'm still able to park inside my work's parking structure. The con was during installation, this unit did not come with a sleeve that bridges the gap from the headliner to the fan itself. It did not sit flush and the manual **** that pushes up the metal rod(the longest one) does not reach because of it. I have to rely on the remote. Very good purchase and it's perfect for what i use it for.
We’re glad to hear the NomadicArk fan has been working well for your setup, especially the low power draw, quiet operation, remote control, and low-profile fit for parking structures.
One note on the install: the AirPlus is designed differently than a MaxxFan and does not use or include an interior sleeve. The fan is rated for a maximum roof thickness of about 3 1/8'. By comparison, a MaxxFan 7500K includes a sleeve-style interior garnish that can accommodate a thicker roof/headliner stack, up to about 6'.
Thanks again for the feedback, and we’re happy it ended up being a great fit for your van.
