Environmentally friendlyTheoretical principle and how it works:The evaporative coolers use OFS evaporative cooling pads as media. A system of water distribution and a pump keep the pad continuously wet, Inside the machine is a large axial fan which sucks the air from the outside through the pad. When the air goes through the pad which is saturated the air gets coolerThe cool air is then forced by the fan into the premises.Model No. Max AirflowVoltage PowerAirflow StyleWater Consumption Prod.
