Evaporative Cooling System that Delivers Cold Air – Not Moisture

Fresair delivers cool Eco-Friendly comfort where traditional AC systems can’t!

Fresair is powered only by the vehicle’s battery, allowing the system to run continuously even when the engine is off!

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 systemIt 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.
