Universal Cool Boss Cb-28 Medium-duty Commercial-grade Air Cooler No Hidden Fees [5vBGSNyn]

CB-28 Medium-Duty Commercial-Grade Air Cooler by Cool Boss

Stay cool and productive with the Cool Boss CB-28, a powerful medium-duty evaporative air cooler designed for industrial and commercial spaces. Perfect for use in warehouses, workshops, or outdoor job sites, the CB-28 utilizes advanced Honeycool™ evaporative media to deliver efficient, eco-friendly cooling at a fraction of the cost of traditional air conditioners. With a high air output of 9,020 CFM and a generous 2,125 sq. ft. coverage area, this cooler is built to handle intense heat without breaking your budget.

The CB-28 features an 80-gallon auto-refilling water reservoir, allowing hours of uninterrupted operation—even in locations without a continuous water supply. The combination of a 28” Blue Flex™ axial fan and variable fan speed/water flow controls ensures maximum airflow control for consistent, targeted cooling. Operating on standard 110V power, there’s no need for special wiring, making the CB-28 convenient and easy to use in almost any setting.

But the CB-28 isn’t just about airflow—it’s also packed with user-friendly extras. A built-in 80W LED floodlight brightens up your workspace with 4000 lumens of lighting, while integrated Bluetooth® stereo speakers let you wirelessly stream music or podcasts. Additional features like soft-touch LED controls, automatic water shutoff, and an antibacterial housing make this unit both functional and safe for daily use. Cool Boss delivers performance and comfort with a smart, efficient, and reliable solution for tough cooling demands.
