Features you've been

dreaming of

This sassy number aka the S7i 12V Air Cooler, comes complete with an enclosed 12L reservoir for convenient water supply and simplified plumbing. And with up to 22 hours of continuous cooling, warm weather traveling will be a total breeze.

Quick & simple


Since the unit includes an internal reservoir, you can expect a simpler first-time and/or retrofit installation. All you’ll need to do is connect the water input to your water supply and your output to a grey water tank using the waterlines and pumps provided for the connections. It’s an ideal install for vans, trailers, tear-drops and the list of vehicle types just doesn’t end.

Designed for your


Energy-efficient is the Fresair S7i 12V Air Cooler’s middle name.  While running on <10A/h at full power, its four directional vents produce powerful cooling for up to 22 hours thus creating up to a 40˚F drop in temperature (scroll down to view the chart and proof we’re good at math.)

Let’s just say it can certainly cool your jets with the plus side of not sounding like a jet since it runs without a compressor. And unlike some other air conditioning units, this unit doesn’t have to rely on a loud generator or even your engine, it can be powered via battery.



A massive temperature drop of up to 40°F between ambient temperature and vents can be reached! On average at 85°F ambient temperature, you will see 20°F+ drop. The hotter the environment the larger the drop.


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.


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.


With only needing to replace two pumps (injection & return) and a pine filter approximately once a year, the Fresair S7i 12V Air Cooler is low maintenance.
