Specifications
Model RKF505 RKF405
Caution・After every operation, stop the cooler by Auto-stop operation in order to dry the cooling element. The drying operation lasts for about 20 - 40 minutes. Thereafter, operation stops automatically. ・Operating this cooler in closed area may result in the increase of humidity. This may then cause not only decreased cooling effect but rust with other equipments or materials.
*1 The above specifications are derived when the temperature of air at inlet is 30℃(86F) and its relative humidity is 50%.

An Earth Friendly Product
CO2 Reducing Cooler
RKF Series has adopted the natural cooling phenomenon from a waterfall and applied it to its cooler which creates a comfortable working environment. Cooling air by vaporizing water, this vaporization cooling system emits no heat exhaust, is earth friendly and health-oriented.
Cool air by water evaporation
NEW
Supply cool air widely and farther away
Economic efficiency
Easy cleaning for water tankEasy transport
Adjustable speeds
Easy operation and maintenance
❶ Water in the tank is pumped up to water spray bar and then sprayed on cooling element.❷ Evaporation occurs in the cooling element which causes actual temperature of the air to decrease.❸ Large fan distributes the cooled air farther away.

New useful function for RKF505
Cool air can reach whole bodyby vertical auto-louver
Cool air can cover a wide rangeby horizontal auto-louver
This wire mesh prevents accidental insertion of fingers or objects.
Equipped with casters for easy moving
Water tank is easily taken out by releasing joint connectors. Water tank is easy to clean due to its large hole.
After every operation, cooling element is dried using the Auto-stop operation. This helps to keep the cooler clean
Easy touch button selector for high, medium or low air volumes

Water tank is easily filled with water via a hose. Auto water supply can be chosen as well.
Easy water supply
Sensible body temperature is decreased by the increase in wind speed.
RKF never emits exhaust heat unlike an air conditioner because RKF is not equipped with a compressor.
