High-Volume Cooling Performance

The Big Ass Fans COOL-SPACE® 500 provides airflow ranging from approximately 16,500 to 24,000 CFM to distribute cooled air throughout large work areas or toward targeted locations. The manufacturer specifies coverage of up to 6,500 square feet under suitable operating conditions. With its 50-inch fan and variable-speed drive, the unit is designed for demanding applications that require substantial airflow and supplemental cooling. Under favorable conditions, evaporative cooling can lower air temperature by up to 33°F (18°C). Actual performance depends on ambient temperature, relative humidity, ventilation, and the operating environment.

Direct Evaporative Cooling Technology

The Big Ass Fans COOL-SPACE® 500 uses direct evaporative cooling technology to cool incoming air as water evaporates from its 8-inch-thick, cross-corrugated, angle-fluted cellulose cooling media. An integrated water distribution system supplies water to the media, while the fan draws air through the wetted surface and delivers cooled airflow into the surrounding space. The cellulose media is treated with thermosetting resin to improve strength and help resist algae growth. This design provides targeted evaporative cooling for large, well-ventilated commercial and industrial spaces without relying on a conventional refrigerant-based cooling cycle.

Airflow and Distribution

The Big Ass Fans COOL-SPACE® 500 features a 50-inch-diameter fan and a variable-speed drive that delivers approximately 16,500 to 24,000 CFM of airflow. Adjustable fan-speed operation allows users to regulate air delivery according to changing environmental conditions and cooling requirements. The direct-drive motor design eliminates belt-driven transmission components, while the high-volume airflow supports localized cooling in large warehouses, manufacturing facilities, service bays, and other open work areas. The published sound level is approximately 60 dBA under specified test conditions; actual sound levels may vary with installation and operating conditions.

Portable and Flexible Installation

The self-contained design allows the Big Ass Fans COOL-SPACE® 500 to be positioned where supplemental cooling is needed without requiring a permanent HVAC installation. The unit measures approximately 74 inches long, 35.6 inches deep, and 88.1 inches high. Its heavy-duty housing and caster wheels support deployment in large commercial and industrial environments. The integrated reservoir allows operation without a continuous external water connection for a limited period, while a standard garden hose connection supports ongoing water replenishment when a suitable supply is available. Position the unit on a stable surface with adequate clearance and ventilation in accordance with the manufacturer's installation instructions.

Water Management

The Big Ass Fans COOL-SPACE® 500 incorporates a 64-gallon (approximately 242-liter) water reservoir to supply its direct evaporative cooling system. The reservoir supports extended operation without a continuous external water connection, with actual runtime depending on operating conditions and water consumption. The unit accepts water through a standard garden hose connection or a compatible portable water supply. An integrated float valve regulates the water level, while a low-water shutoff helps protect the pump when water levels become insufficient. An accessible reservoir cap facilitates water treatment, and the drain plug and flush valve support reservoir drainage and cleaning. Follow the manufacturer's specified inlet-water pressure limits when connecting the unit to a water supply.

Controls, Comfort and Electrical Connection

The Big Ass Fans COOL-SPACE® 500 incorporates an onboard LED control panel, variable-speed fan control, an occupancy sensor, and a timer function. Remote-control and connected-control capabilities may vary by the installed control configuration. The occupancy sensor and timer support convenient operation in facilities where cooling requirements change throughout the day. Model E-500-5001 is designed for a 120 V AC, single-phase, 60 Hz electrical supply and draws approximately 16.5 A. The manufacturer's technical documentation specifies the required branch-circuit protection; verify the applicable circuit and plug requirements against the current E-500-5001 installation documentation and the unit's nameplate before installation. Do not substitute the electrical specifications for the E-500-5002 model, which uses a different power supply.

Commercial and Industrial Applications

The Big Ass Fans COOL-SPACE® 500 is designed for large, well-ventilated indoor and outdoor environments, including warehouses, manufacturing facilities, service bays, workshops, and stadiums. Its high-volume airflow, integrated water reservoir, and portable construction make it suitable for targeted cooling in spaces where permanent air-conditioning systems may be impractical or insufficient for localized heat loads. 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 Big Ass Fans COOL-SPACE® 500 features a heavy-duty cabinet and caster wheels designed to support movement between suitable work areas. Its approximately 74-inch length, 35.6-inch depth, and 88.1-inch height accommodate the large fan assembly and integrated water reservoir required for high-volume cooling. The reservoir supports temporary operation without a continuous water connection, while the hose connection enables water replenishment during extended use. Before moving the unit, follow the manufacturer's instructions for securing the power cord, managing the water supply, and positioning the cooler safely.

Service and Maintenance

The Big Ass Fans COOL-SPACE® 500 incorporates treated cellulose cooling media designed for durable operation in evaporative cooling applications. Routine maintenance includes inspecting and cleaning the cooling media, cleaning the reservoir, checking the water distribution system and float valve, and inspecting the drain plug and flush valve. The accessible reservoir cap supports convenient access for approved water treatment products. Follow the manufacturer's operation and maintenance manual for cleaning intervals, water treatment, seasonal storage, and inspection procedures. Disconnect electrical power before servicing internal components or performing maintenance that requires access to electrical or moving parts.
