For smaller rooms up to 200 square feet in your office or home, the Haier Portable Air Conditioner is a compact cooling unit that delivers 8000 BTUs of cooling power. Like all air conditioners and dehumidifiers, this single-hose 3-speed portable air conditioner extracts water as it cools, and uses auto-evaporation to eject most of the extracted water out the exhaust hose. 3 separate modes allow you to use this model as a cooling unit, dehumidifier, or a fan to circulate air. It's also eco-friendly, using R-410A refrigerant that won't impact the ozone layer, and RoHS-compliant, which means the unit is free of lead, mercury, and other hazardous substances. The compact unit rides on casters that let you move it freely from room to room. It also fits double-hung, sliding, and casement windows; an installation kit with hose, hose adapters, window panel kit, and window panel adapter is included. The easy-to-use remote and 24-hour timer let you customize operation to fit your schedule. 900 watts and 115 volts. 24.4 x 17.9 x 13.1 inches. 56.1 pounds.
