When dry and warm air contact water, the water will evaporate.
Then the air lose its heat and the temperature decrease.
RKF series adopt this natural principle and are products which
pursue its performance, usability, coolness and comfort.

RKF achieves less power consumption because it produces cool air by natural principle.
The power consumption of RKF is one-seventh of mobile air conditioners.

■ RKF403		230W	(230V 50Hz)
		290W	(120V 60Hz)
■ RKF503		390W	(230V 50Hz)
		520W	(120V 60Hz)

RKF produces comfortable cool air and distributes cool air to wide area with oscillating auto-louver.
In addition, RKF doesn't equip compressor, so it doesn't emit exhaust heat.

Contributing to prevent global warming
Because of less power consumption, RKF is energy-saving product. In addition, RKF doesn't have a refrigerant gas such as a flon. Therefore, RKF can achieve CO2 reduction.

Global greenhouse gas(GHG) emission per month
■ RKF403 21.5kg
■ RKF503 44.0kg

The cooling efficiency of RKF depends on ambient temperature and humidity. More cooling effect can be expected if temperature is higher and humidity is lower.
