Cool Boss CB-24 Evaporative Air Cooler - Swing Louvers - 24 Inch Fan

Introducing the Cool Boss CB-28 Evaporative Air Cooler—the perfect blend of size, power, and convenience, designed to keep your spaces cool and comfortable, whether you’re hosting an outdoor event, working in a large industrial area, or simply enjoying a summer get-together. As a medium-duty, commercial-grade cooler, the CB-28 delivers powerful cooling performance that you can rely on, all while using eco-friendly and cost-effective evaporative cooling technology.

Powerful Cooling for Large Spaces

The CB-28 is built to handle large industrial spaces with ease, delivering an impressive 9,020 CFM of cool, refreshing air and effectively covering areas up to 2,125 square feet. Whether you're using it indoors or outdoors, this cooler ensures that everyone stays cool and comfortable, even in the hottest summer months. With a massive 80-gallon auto-refilling reservoir, the CB-28 can run for hours without needing a refill, making it ideal for locations without a continuous water supply.

Advanced Honeycool™ Technology

Equipped with four Honeycool™ evaporative media pads, the CB-28 excels at transforming hot, stuffy air into a cool, refreshing breeze. These resin-covered honeycomb pads act as a pre-chiller, soaking up water like a sponge and maximizing evaporation efficiency. As air passes through the pads, the phase transition from liquid water to vapor occurs, significantly lowering the temperature of the air and creating a comfortable environment instantly.

Variable Fan Speeds and Water Flow Control

The CB-28 offers variable fan-speed settings and water-flow controls, allowing you to precisely adjust the cooling output to match your needs. Whether you need a gentle breeze or a powerful blast of cold air, this cooler gives you full control over your cooling experience.

Feature-Packed for Enhanced Productivity

The CB-28 is more than just a cooler—it’s a fully equipped workhorse designed to enhance productivity and comfort in any environment. It comes with an adjustable 80W outdoor-rated floodlight that pumps out 4000 lumens of super-bright light, perfect for illuminating large work areas or outdoor spaces during evening events. The built-in Bluetooth® audio player with powerful stereo speakers allows you to stream your favorite music, podcasts, or radio stations, creating a more enjoyable and focused work atmosphere.

Integrated Negative Air Ionizer

To top it all off, the CB-28 includes a germ-zapping negative air ionizer that helps clear the air of airborne particles and allergens, improving air quality and making your environment healthier and more comfortable.

Efficient and Easy to Use

The CB-28 operates on standard household current, so there’s no need for expensive wiring or complicated setups. Its 28-inch Blue Flex™ fan, powered by a 1/3 HP motor, uses a venturi fan cone to concentrate airflow and create a powerful, directional blast of cold air. The fan’s axial-flow design ensures efficient air movement at both low and high RPMs, reducing energy consumption and enhancing cooling performance.

The Cool Boss CB-28 Evaporative Air Cooler is the ideal solution for anyone looking to stay cool, comfortable, and productive in large spaces. With its powerful cooling capabilities, advanced features, and energy-efficient design, the CB-28 is a fan-favorite for a reason. Make every summer event, workday, or gathering more enjoyable with the cooling power of the CB-28.
