Cool down with this 9,000 BTU (5,300 SACC) portable air conditioner by Danby, perfect for spaces up to 150 square feet. To help maximize your comfort, the 3-in-1 design (air conditioner, fan, and dehumidifier) helps ensure you feel comfortable no matter the weather! Its four castors make this unit easy to move from room to room, and the single-hose design efficiently exhausts warm and humid air out. In addition, the 24-hour programmable timer allows for better control of when the unit operates - which reduces costs and helps you save on your monthly utility bill. SACC is short for Seasonally Adjusted Cooling Capacity.
