The excess water that travels through the pine filter goes through water channels and passes through (2) additional sub filters ending up inside the small reservoir built into the front of your Fresair. The return pump is located inside the small reservoir which takes all excess water and pumps it back into the main reservoir […]
There are a few options here. You could connect the S7i ‘in’ hose to the vans pressurized water supply through a valve you could open, just like you connect to a sink faucet. The ‘out’ hose could just vent outside or back to the main tank. The S7i works well for teardrops or step-vans where […]
No, ice will not hurt the system but it is not necessary as the difference in thermal sensation will be minimal.
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 a 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. […]
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.
You can get an idea of how much cooling can be expected in a particular environment by taking a look at the below graph which shows the temperature of the air blowing out of the Fresair unit versus the outside air temperature, in various relative humidities. Even in higher humidities a lot of comfort and […]
While dependent on the outside temperature, 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 […]
Fresair is actively tested 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 […]
