KAISAI ONE+ wall mounted air conditioners (KRX)

Product description

The KAISAI ONE+ wall air conditioner is a series of wall air conditioners combining modern air purification functions with extremely simple installation and maintenance.

Cold Catalytic and Bio HEPA filters effectively remove chemicals and retain up to 99% of dust particles, fungi, bacteria and viruses, while air ionisation further breaks down and eliminates microorganisms from the environment.

The new design of the air conditioner and the optimised arrangement of the individual components inside the unit

ensure time-saving installation and daily maintenance. Through the use of modern technology and the R32 refrigerant, the air conditioner can operate in a wide range of outdoor temperatures.

Comfort of use is ensured by a modern wireless remote control and WiFi function as standard, allowing the unit to be controlled via a mobile phone or tablet.
