Fast Cooling: Cool rooms quickly from corner to corner, so feel comfortable wherever you are. Digital Inverter technology cools the air 43% faster. Its advanced design also has a 15% larger fan, 18% wider inlet and 31% wider blade. So cool air is dispersed farther and wider, reaching up to 15 meters. Copper Anti-bacterial Filter: Keep the air conditioner working efficiently with less effort. The Copper Anti-bacterial Filter is located outside, on the top, so it can easily be removed and cleaned. Its dense mesh keeps the Heat Exchanger clean and a Copper Sulphide coating helps protect you from inhaling harmful bacteria. 3-Step Auto Clean: Keep the inside of the air conditioner hygienic by doing nothing! After it has been working, the Auto Clean function automatically dries the Heat Exchanger using a 3-step process. It removes moisture by blowing air for between 10 to 30 minutes. So it prevents the buildup of bacteria and odors. 5-Step Convertible Cooling: Save energy, but still stay cool. The 5-step Convertible Cooling lets you adjust the compressor operation in 5 steps, from 40% to 120%, to suit your changing cooling needs, using the minimal amount of energy. You can also use it to reduce your daily energy consumption whenever you want. Durafin Ultra: Safeguard the Heat Exchanger from damaging corrosion. The Durafin Ultra has an anti-corrosive layer and a hydrophilic layer that protect the Heat Exchanger from rust. Its superb corrosion-resistance was proven in a Salt Spray Test (SST). Coated Copper Tube: Enjoy a longer-lasting performance and save money. The Heat Exchanger?s coated copper tubes have 7.5x better corrosion resistance, protecting it against harmful environmental conditions, like dust and pollutants. It extends the lifespan, improves reliability and reduces maintenance costs. Triple Protector Plus: Enjoy a long-lasting performance in challenging environments. Triple Protector Plus technology prevents damage from power surges and fluctuating electrical currents, without a separate voltage stabilizer. Its anti-corrosion coating also protects the condenser and cabinet in harsh conditions. R32 Refrigerant: Protect the planet by reducing the impact of climate change. The air conditioner uses the next generation R32 refrigerant, which helps conserve the ozone layer and has a low impact on global warming compared to conventional R22 or R410A refrigerants. So it?s much more environmentally friendly.
