High-Volume Cooling Performance

The Cool Boss CB-14SL provides maximum airflow of 2,300 CFM through its 14-inch-diameter axial-flow fan. The manufacturer's installation and operation manual lists an effective cooling area of approximately 850 square feet, while the Cool Boss Airflow Xtreme brochure lists coverage of up to 1,005 square feet for the CB-14 product family. Actual coverage depends on the environment, ventilation, humidity, and operating conditions. The manufacturer states that the cooler can reduce surrounding air temperatures by up to 26°F under favorable conditions. Three fan-speed settings allow users to select airflow according to changing cooling requirements.

Honeycool™ Direct Evaporative Cooling Technology

The Cool Boss CB-14SL uses direct evaporative cooling technology to cool incoming air as water evaporates from its Honeycool™ evaporative media. The water distribution system supplies the media, while the axial-flow fan draws air through the wetted surface and delivers cooled airflow into the surrounding space. The manufacturer identifies Honeycool™ media as a durable, long-lasting evaporative cooling solution. This design provides targeted cooling without relying on a conventional compressor-based refrigeration system. Evaporative cooling is generally most effective in hot, dry conditions, and performance decreases as ambient relative humidity increases. Adequate ventilation is essential because the system adds moisture to the air.

Airflow and Distribution

The Cool Boss CB-14SL features a 14-inch Blue Flex™ axial-flow fan with three selectable fan speeds and maximum airflow of 2,300 CFM. Its automatic swing louvers oscillate to distribute cooled air across a wider area, helping improve air circulation in garages, workshops, automotive service bays, and other workspaces. The integrated control panel allows users to select a suitable fan speed according to changing cooling requirements. The manufacturer's installation and operation manual lists a sound level of approximately 64 to 72 dB. Actual sound levels may vary with operating conditions and the surrounding environment.

Portable and Flexible Installation

The self-contained portable design allows the Cool Boss CB-14SL to be positioned where supplemental cooling is needed without requiring a permanent HVAC installation. The manufacturer's specification table lists dimensions of approximately 30 inches wide, 22 inches deep, and 47 inches high, with an empty weight of approximately 79 pounds. Durable swivel casters support movement between work areas. The integrated water reservoir enables operation without a continuous external water connection for a limited period, while the water inlet connection supports replenishment from a compatible water source. Position the cooler on a stable surface and follow the manufacturer's installation instructions before operation.

Water Management

The Cool Boss CB-14SL incorporates a 15.6-gallon (approximately 59-liter) water reservoir to supply its direct evaporative cooling system. The manufacturer's Airflow Xtreme brochure lists water consumption of approximately 0.75 to 1.25 gallons per hour, depending on operating conditions. A mechanical float valve automatically shuts off the external water supply when the reservoir reaches its maximum fill level. The internal water pump incorporates an automatic low-water shutoff to help protect the pump when water levels become insufficient. The manufacturer specifies a maximum water-source pressure of approximately 99.5 PSI in the installation and operation documentation. The inlet water temperature must remain below 45°C (113°F). Follow the manufacturer's instructions for filling, draining, and cleaning the reservoir.

Controls, Comfort and Electrical Connection

The Cool Boss CB-14SL features an integrated control panel with three fan speeds and automatic swing louvers for adjustable airflow distribution. The standard CB-14SL model operates on a 110 V AC, single-phase, 60 Hz electrical supply and draws a maximum of 1.0 A, according to the manufacturer's installation and operation manual. The unit includes a 15-foot power cord and must be connected to a grounded circuit protected by a circuit breaker or fuse. The manufacturer specifies a GFCI-protected electrical connection for safe operation. Verify the specifications on the unit's nameplate and the applicable manual before installation. The CB-14SLH is a separate high-voltage model with different electrical requirements.

Commercial and Industrial Applications

The Cool Boss CB-14SL is designed for garages, workshops, automotive service bays, warehouses, patios, and other well-ventilated work areas requiring supplemental cooling. Its compact footprint, adjustable fan speeds, automatic swing louvers, and portable construction make it suitable for localized cooling where installing a permanent air-conditioning system may not be practical. Direct evaporative cooling is generally most effective in hot, dry conditions, and cooling performance decreases as ambient relative humidity increases. Adequate ventilation is essential because the system adds moisture to the air. Confirm environmental suitability and operating requirements before deploying the cooler in a particular facility.

Mobility and Deployment

The Cool Boss CB-14SL features a portable cabinet and durable swivel casters designed to support movement between suitable work areas. Its approximately 30-inch width, 22-inch depth, and 47-inch height accommodate the fan assembly and integrated water reservoir while maintaining a space-saving footprint. The unit weighs approximately 79 pounds when empty and 208 pounds when the reservoir is full. The reservoir supports temporary operation without a continuous external water connection, while the water inlet connection supports replenishment during extended use. Lock the casters during operation and follow the manufacturer's instructions for managing the water supply, securing the power cord, and positioning the cooler safely.

Service and Maintenance

The Cool Boss CB-14SL incorporates Honeycool™ evaporative media and durable ABS plastic housing with antibacterial properties. Routine maintenance includes inspecting and cleaning the media panels, cleaning the water reservoir, checking the mechanical float valve and water distribution system, and inspecting the power cord and plug for damage. Keep the reservoir filled with clean water during operation and drain or clean the unit as directed in the manufacturer's instructions. Do not use high-pressure water on installed media panels; remove and clean the panels according to the manufacturer's maintenance procedure. Disconnect electrical power before servicing internal components or performing maintenance that requires access to electrical or moving parts.
