About the Fresair


Fresair 12V DC Air Conditioner


Simply put, the Fresair 12V DC Air Conditioner is a patented evaporative cooling unit that produces glorious cold air and a powerful breeze when you need it the most.


Fresair is conveniently designed to utilize minimal power from your 12V system to produce a satisfying breeze even during the hottest desert-like days.

Using its built-in pump, it circulates conservative amounts of tap water from its reservoir (included) through an anti-bacterial, anti-fungal organic pine filter to produce humidity-free cooling and conveniently accommodates a variety of applications. As an added bonus, the pine filter even helps to filter dust and pollen out of the air. Insert mic drop here.

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°F+ degrees! It does just what a Fresair 12V DC Air Conditioner should do—keep it cool.

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.

You’ve got questions, we’ve got answers.

Q. How does an evaporative cooling system work in humid climates?

A. We have tested Fresair in high humidity climates like Florida and the cooling sensation works great, however, the evaporative process lessens at humidity levels over 80%. Even when the humidity levels are very high the fan alone provides fast-moving cooling air. Fresair delivers cold air not moisture unlike systems of the past.  Our pine filter absorbs the moisture and then passes through two additional filters resulting in cool clean air, not mist. For further detailed information on performance levels in differing temperatures and relative humidity levels see below.

Q. Does your system require distilled or filtered water?

A. No, all that is required is tap water. If you live in a climate where the water is very hard and you are concerned about calcium build-up, a chlorine tablet can be dropped into the reservoir every other month.

Q. Can you tell me about the preventive maintenance, frequency and cost?

A. There are two pumps for this system (injection – pumps water from the reservoir up to the roof, and return – pumps any excess water extracted from the pine filter back into the reservoir). The pine filter can be power washed but it is recommended that both pumps and pine filter be replaced once a year (depending on usage and proper maintenance). Your annual cost to keep your Fresair system running optimum should be around $100, contact your authorized Fresair dealer for a quote.

Q. I have a 48V electric golf cart, can I power it straight to one 12v battery?

A. No, on electric golf carts you need to connect the power source to a converter, this will draw power equally from your battery pack rather than draining one battery. Most golf carts already have a 12V converter fitted to run things like lights and sound systems.

Q. I have a gas powered golf cart, can I use your system?

A. Yes, but please remember that if the engine is not running the battery will drain. The system does draw minimum power though (< 10A/h) so it is not a large load on the battery, however, you should run the engine occasionally so the alternator is charging the battery.

Q. My golf cart roof is not flat, can your system still be installed?

A. Flat roofs work the best, but as long as the system is flat or facing down slightly towards the front (the return pump gathers water from the front of the unit) the system will function properly. The unit weighs about 25lbs, so your roof will need to be able to support that weight or will need support bars added. Contact an authorized Fresair dealer to have your cart inspected by a certified tech.

Q. Can I buy directly from you?

A. Yes, please contact us for pricing. Professional installation is preferred but not necessary if you’re handy.

Q. What is the warranty and do you offer an extended warranty?

A. Fresair offers a one-year manufacturer warranty for your system. Contact your authorized Fresair dealer to inquire about extended warranty packages.

Q. Do the covers come in any other color besides white?

A. Yes, At this time the covers come in white and black. The cover is constructed from ABS plastic with UV protection which can be custom painted at the dealer level to match any roof or body color.

Q. How many different types or styles of Fresairs are there?

A. There are currently two models available, the S6 which uses an external reservoir, and the S7i which uses an internal reservoir. The S6 is recommended for the majority of installations, however, the S7i can be used where a self-contained unit is preferred (normally step vans). For golf carts and most van conversions the unit of choice is the S6. The S6 is universal for all makes and model of golf carts, including both gas and electric.

Q. How many different types of reservoirs are there?

We do offer several reservoir options depending upon application:

For golf carts, there are two options: the 8L under the seat (size of a battery) & the 5L remote fill (normally installed within a wheel well). Both reservoirs are not visible to the eye when installed and offer a very convenient waist-high filling system.

For step vans and van conversions there is a larger 18L flat reservoir (installs vertically or horizontally internally) that can be filled by hose, by the pump from your main water tank, or the unit can even be connected directly to your main tank. Alternatively, the S7i has an internal reservoir, within and out hoses. For installations like teardrops or step vans, this is an ideal and rapid solution.

Q. Will both of the golf cart reservoir systems get me through a round of golf?

A. Yes, water consumption is based upon the exterior ambient temperature but you should get an absolute minimum of 4 hours of cooling sensation.

Q. How cold does the air get from your product?

A. This depends on the outside temperature but you should see 20°F – 40°F reduction from the ambient temperature to the air emitting out of the vents. Fresair is not a traditional air conditioner, there are no coolants or compressors, which would kill the batteries. Fresair is a green product powered by a 12V power source, normally just the regular vehicles’ existing battery or batteries, drawing minimal power whilst cooling the air with tap water and pine using evaporation.

Q. Do I need to fill the reservoirs with ice?

A. No, ice will not hurt the system but it is not necessary as the difference in thermal sensation will be minimal.

Q. How easy is the unit to install?

A. Professional installation is recommended but can be accomplished by a skilled owner.

A hole to accommodate the airbox needs to be cut from the roof (template provided). The unit drops onto the roof and is sealed by foam and silicone gel and mounted using 4 bolts.

The water lines and power lines, contained within a single harness, are run from the unit to the reservoir and battery. The harness contains two water pipes, one to feed the unit with water, the other to return water from the unit to the remote reservoir, as well as the 12V power cable. On golf carts, the loom runs over the top of the roof and down one of the roof supports into the cart body. We also provide a unit where the harness runs under the roof, especially clean when you have a headliner. On vans, the loom runs internally along the ceiling and down the side to wherever you choose to mount your reservoir. You can also install Fresair to use your main freshwater tank rather than a separate reservoir.

For golf carts, there are many different roof types out there, so the strength of the roof, curvature of the roof, and where the mounting bolts are to be located need to be analyzed. There are multiple mounting bolts patterns though so there are options to work with virtually any roof. If your roof cannot hold a 25lb weight, support brackets need to be added on the underside of the roof, but most roofs are fine.  The harness runs towards the back of the roof and generally to the left down the rear left roof support strut and into the body of the cart. Depending upon your cart a 1” hole may need to be cut to allow the harness to pass through the body. The harness then needs to be connected to the reservoir and 12V power converter. There are two types of reservoirs, an 8L model that fits under the seat where the batteries are located (if you have space) and a 5L model that is usually mounted under the left rear wheel-well and connected through the body to a “gas-cap” style remote fill. The water pipes then need to be connected to the reservoir and the 12V power cable to the converter.
