Cool Boss CB-19L Evaporative Air Cooler with Swing Louvers - 19-in. Blades
Personal Cooling Power for Garages, Patios, and Dry Climates
The Cool Boss CB-19SL Personal Space Cooler delivers powerful, efficient cooling for garages, workshops, patios, home gyms, and outdoor living spaces in hot, dry climates. Built for areas with low humidity, this portable evaporative cooler uses water and airflow to create a refreshing stream of cool air without the high energy costs, refrigerants, or complicated installation required by traditional air conditioning.
With 6,840 CFM of airflow and a 19-inch axial fan, the CB-19SL is designed to move serious air through personal and small-space cooling zones. Whether you are working in the garage, training in a home gym, relaxing on a covered patio, or trying to cool down a backyard workspace, this Cool Boss evaporative cooler gives you a smarter way to stay comfortable when temperatures climb.
Portable Garage Cooler with Smart Controls and Easy Setup
The CB-19SL is built with a durable antibacterial HDPE shell that stands up to regular use while staying light enough to move where cooling is needed. At only 40 lbs. dry, with a compact footprint and a tall 66-inch design, this portable garage cooler fits well in tight workshop corners, small patios, home gyms, and covered outdoor spaces.
Smart operating features make cooling simple. A built-in timer, three-speed fan, and automatic water shut-off help manage comfort, water use, and energy efficiency without babysitting the unit. The 15-foot power cord provides convenient reach, and the cooler is compatible with standard 120V power, with optional 208 to 230V setups available for select applications.
Quiet, Low-Cost Alternative to Traditional Air Conditioning
Traditional air conditioning can be expensive to install, costly to run, and overkill for garages, patios, and personal workspaces. The Cool Boss CB-19SL evaporative air cooler gives users a more efficient option for dry climates by using water, airflow, and advanced cooling media instead of refrigerants or compressor-based cooling.
Operating at only 57 to 62 decibels, the CB-19SL delivers strong airflow without overwhelming your space with noise. You can work, talk, listen to music, watch TV, or take a call while enjoying a steady blast of cool air. For anyone looking for a portable evaporative cooler that balances airflow, efficiency, and comfort, the CB-19SL is built to help you cool smarter.
Honeycool Evaporative Media for Efficient Cooling Performance
At the center of the CB-19SL is Cool Boss Honeycool™ evaporative media, engineered to improve cooling performance while helping reduce water usage compared to standard cooling pads. As hot air passes through the water-saturated media, evaporation naturally lowers the air temperature before the cooler pushes that fresher air into your space.
The CB-19SL is ideal for dry environments with humidity levels of 60% or less, where evaporative cooling can perform at its best. With no compressor and no Freon, this personal swamp cooler offers a cleaner, lower-maintenance alternative to traditional AC for garages, workshops, patios, and home work areas.
Simple Cooling Controls
Built-in controls make it easy to adjust airflow, set the timer, and dial in the cooling level you need. With three fan speeds and automatic water shut-off, the CB-19SL keeps comfort simple without wasting water or energy.
