The Cool Boss CB-28 evaporative air cooler is designed to provide powerful cooling for large spaces while incorporating modern features that make it more than just an industrial fan. Built with a 28-inch fixed style fan, this unit is capable of pushing up to 10,645 cubic feet per minute of airflow, ensuring wide coverage across large environments. Whether you are cooling a workshop, warehouse, event space, or outdoor area, the CB-28 is a reliable choice that balances strength, efficiency, and innovative functionality. With a cooling area rating of 2,125 square feet, this unit is well suited for commercial and residential applications where traditional cooling methods may not be practical or cost effective.
The heart of the CB-28 is its evaporative cooling system. Air is pulled through four Honeycool media pads that are designed to retain water while maximizing surface area. As hot air moves through the pads, evaporation lowers the temperature of the air before it is circulated back into the environment. This simple yet effective method of cooling reduces the need for energy-intensive refrigeration while still delivering a refreshing drop in ambient temperature. The system is supported by an 80-gallon water reservoir, which allows the cooler to run for extended periods without interruption. The auto-refill capability ensures consistent operation, and water consumption remains between 2.6 and 3.2 gallons per hour depending on settings.
Flexibility is built into the operation of the CB-28. Variable fan speeds allow you to tailor the airflow to match the needs of your space, from a mild breeze to a strong blast of cool air. Water flow can also be adjusted to optimize the balance between cooling efficiency and water usage. The sound profile ranges from 60 to 100 decibels depending on speed, making it manageable in most environments. Control options include a soft touch LED panel and a remote control with its own holder, giving operators the convenience to adjust performance without needing to be near the unit.
The CB-28 evaporative air cooler is not limited to cooling alone. This cooler includes a negative ionizer that helps to freshen and clean the air as it circulates. A built-in LED floodlight with 80 watts of power and 4,000 lumens of brightness makes it possible to illuminate large workspaces without requiring additional lighting equipment. To further enhance the experience, integrated Bluetooth stereo audio provides entertainment or communication functions, allowing users to connect their devices and stream music or podcasts while working or relaxing. These features make the CB-28 more versatile than traditional evaporative coolers that focus on airflow alone.
Durability is another strength of this machine. The housing is constructed from high density polyethylene that resists impact and offers antibacterial properties. The unit weighs 275 pounds and is supported by swivel casters that make it easier to maneuver when necessary, despite its substantial size. Dimensions measure 52 inches wide, 37 inches deep, and 76.5 inches tall. A 15-foot power cord, GFCI plug, and UL certification ensure safe operation in a variety of settings. Shipping dimensions are slightly larger at 57 by 40 by 73 inches with a shipping weight of 294 pounds.
