Fresair Van Conversion Interior

Fresair is introducing a brand-new low power roof-mounted A/C unit for Van Conversions, RV'S and trailers.
With an extremely low power consumption of <10A/h on maximum setting, a low sleek roof-top profile of 3.7", lightweight at 25 lbs, cool running and quiet the Fresair S6 is ideally suited to revolutionize rear air conditioning for recreational vehicles.
After several years of refinement for Golf Carts and Stepvans we are customizing our Fresair Series 6 cooler into the VanLife market... you're welcome.

Low Power – Fresair runs <10A/h at full power (tests read approx 7A/h) which is only slightly more than a simple roof fan. Compared to traditional rooftop AC units you’ll be using approximately 20x less power.

Light Weight – Weighing in at only 25lbs you’ll be less top heavy and save on payload.

Low Profile – The unit has a low sleek profile of 3.7”, streamlined (no wind noise) and it’s sexy as hell. It’s form factor is so low it will even fit underneath roof racks or solar panels.

Adjustable Ceiling Vents – The internal control panel has four directional air-craft style vents to direct air where you need it. Spread air between a kitchen and sleeping area. Close vents to concentrate air on a certain area.

Powerful Cooling – Temperature drop between ambient temperature and vents can reach -40’F! On average at 85’F ambient temperature you will see 20+’F drop. The hotter the environment the larger the drop. 

Air Flow – WARNING: The airflow on full blast will literally blow your hairpiece off. Runs even with windows or doors cracked to exchange air every couple of minutes.

Eco-Friendly – Running on water and battery power alone as well triple-filtering the air and running clean, even off solar power alone, Fresair is your green energy solution.

Low noise – External noise is so low as to run all night with no attention from passers by or camping neighbors. Very discreet and no compressors making you the target for noise-police.

Runs Cool – No heat venting from the unit, runs cool even in direct sunlight, you can even install a rooftop tent above it and maintain comfort for all.

Runs Dry – State of the art evaporative cooling technology delivers cool air, not moisture. With a fan-only mode you can also simply keep air moving without cooling. No more sweaty sleepless nights… also acts as a blissful sound soother.

Run with doors open – Traditional AC is designed to work in a sealed off environment. Who wants to keep everything shut up tight when the idea is to be out there enjoying everything freedom has to offer? Our system runs even with open doors, creating a cool air flow. At night just crack a window to keep air circulating and fresh.

Retrofit – Fresair will install easily into any pre-existing standard 14”x14” opening. If you have trouble installing an internal reservoir the new S7i has a reservoir built in, just connect the power to 12v and run “in & out” hoses to fill, internally or externally.

Reservoirs – A slim 18L reservoir is provided but you can go your own way and connect to your fresh water tank, customize your install. Fill the reservoir directly or via a pump from your fresh water tank. Or, just connect directly to your main fresh water tank. Fresair just needs a water feed and return. At peak usage Fresair will use under 1L of water per hour. Run it all day!

Leave it on – Running into the store or restaurant, have a pet in the back, kids hanging out… just leave Fresair running worry free and return to a cool van.

Envy – Yes, you will be the envy of everyone you meet on the road. Recommend our system, gain us another customer and we’ll even send you a check. Want to put out a video step-by-step showing your install or simply enjoying the comfort of Fresair? We’ll love you even more, cha-ching! How’d you like them apples?

Pricing – At a recommended MSRP of $1495 you’ll be way under the cost of traditional A/C units. Contact us for wholesale volume pricing so you can start providing your customers with the most state-of-the-art and efficient van cooling system.

Price $1495. Continental US Shipping $95.

Fresair is a brand new, state of the art and eco-friendly rooftop air conditioning unit.

Unlike traditional air conditioning units that demand high power and run on a refrigerant. Fresair runs on regular tap water and is powered by the vehicle’s existing battery, drawing minimal power and providing cooling to the user of up to 40+ degrees!

The roof-mounted Fresair system is patented and works by forcing air through a moist fibrous organic pine filter, which is both anti-bacterial and anti-fungal. The filter is circulated with water from a remote hidden reservoir. Just fill up the water reservoir, turn on the unit and go!

The cooling effect is generated by evaporation and is triple filtered, feeling dry, unlike a typical “swamp” cooler or misting system. The unit itself is very slimline at only 3.7″ tall but packs a punch with four adjustable vents and our latest smart control panel safeguarding the system. It not only looks great but is also a completely green technology, even filtering dust and pollen out of the air keeping the driver’s well being our top priority.

Please see our FAQ page for details on how well Fresair performs in different levels of relative humidity.
