Fresair 12V DC Air Conditioner

What makes it so cool?

Simply put, it’s a 12v Van Conversion Air Conditioner and also our pride and joy. What makes it better than the rest is its state-of-the-art engineering. Having an evaporative cooling system with not only a powerful and forceful breeze, but also cold air and temperature reductions of up to 40°F. Often traditional air conditioning units demand high power whilst running on refrigerant.  Our van conversion air conditioner can be powered through the vehicle’s existing battery or an installed battery bank recharged via solar and maintains low power consumption–we’re talking approximately 10 amps drawn per hour on max power.

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.

Why is it BETTER than the rest?

We’ve created a whole patented roof-mounted van cooling solution that works as a standalone system when the vehicle is off or as a supplemental system when the van is on. This van conversion air conditioner is powerful enough to keep the kids and pets in the back cool, yet quiet enough to run constantly–even while parked and with the doors open! AND It’s powered only by the vehicle’s battery, allowing the system to run continuously even when the engine is off!

The system works by forcing air through a moist fibrous organic anti-bacterial, anti-fungal pine filter which is then triple filtered and circulated with tap water from a remote hidden reservoir. This means no moisture is produced.

We've made a list of all the reasons, we know you'll love our Fresair Van Conversion Air Conditioner.

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.
