TECXERLLONTECXERLLON 15000 BTU Portable Air Conditioners Cools Up to 800 Sq.Ft, 4-IN-1 Self-Evaporating Portable AC Unit with Dehumidifier, Fan, Sleep Mode, 24-Hour Timer, Remote Control for Large Room, Office
Main highlights- 【Sleep Mode + 24 Hour Timer】In sleep mode, the ac portable air conditioner for room adjusts fan speed and temperature based on the built-in sensor for a quiet environment. Once the room reaches the ideal temperature, the compressor operates temporarily, reducing noise to below 52dB. The 24 hour timer helps save energy, while the temperature display dims automatically for undisturbed sleep. Enjoy a peaceful night with this smart air conditioner. (Note: When set to a lower temperature with the fan at the highest speed, the compressor will operate at full capacity, and the noise level may increase slightly.)
- 【Powerful Cooling for Large Spaces】Beat the heat with TECXERLLON’s 15000 BTU (ASHRAE) portable window air conditioner, engineered with a high-quality energy efficient rotary compressor for faster, more efficient cooling and energy savings. Designed to cool rooms up to 800 sq. ft., it’s perfect for your living room, bedroom, office, or apartment. Enjoy rapid temperature control with adjustable settings from 61°F to 90°F for ultimate comfort, all while reducing energy consumption for a more eco-friendly cooling experience.
- 【Improved Airflow & Adjustable Fan Speeds】Equipped with a powerful fan system, the TECXERLLON portable ac unit provides a 15-75° wide-angle airflow, effectively cooling your room in multiple directions. With three adjustable fan speeds and a maximum airflow of 350 CFM, you can customize the airflow to suit your comfort needs, ensuring even and rapid cooling throughout the room.
- 【Easy to Move & Install】The indoor portable air conditioner features 4 durable 360° wheels and hidden handles for easy movement. The package includes a window sealing kit, exhaust hose, and a high-quality insulated cover for the hose, providing effective heat protection. It fits most vertical and horizontal sliding windows, and for open-type windows, contact us for additional accessories.
- 【Easy Drainage】The TECXERLLON self evaporating portable air conditioner features an efficient self-evaporating system that minimizes the need for frequent draining. Under normal conditions, moisture is automatically evaporated through the air hose. However, during extended use in dehumidifying and low-temperature cooling modes, excess moisture may accumulate in the internal tank. To ensure uninterrupted operation, we recommend connecting the included drain hose for extended use.
- 【4-in-1 Cooling/Dehumidifying/Fan & Sleep Mode】 This versatile portable air conditioner combines four functions—cooling, dehumidifying, fan, and sleep mode—providing year-round comfort. Adjust the temperature from 61°F to 90°F in cooling mode for perfect cooling. With a dehumidifying capacity of 100 pints per day, it effectively reduces moisture in small rooms, while the fan mode circulates air for continuous ventilation. The sleep mode ensures a quiet and peaceful night’s rest, making it perfect for any environment.
- Note: As the compressor inside,the noise may be loud for noise sensitive people. The noise level only drops below 52dB when the unit is in sleep mode (lowest fan speed) and the compressor is temporarily paused.
