• Portable Mobility – Caster wheels allow the cooler to be repositioned as cooling requirements change.
• Variable-Speed Airflow – Adjustable fan-speed control allows users to regulate airflow for different work conditions.
• Flexible Installation – A self-contained design with an onboard water reservoir supports portable operation without a permanent HVAC installation.
• Convenient Water Management – A 16-gallon reservoir, hose connection, and automatic low-water shutoff support convenient operation and help protect the unit when water levels are insufficient.
• Simple Controls and Electrical Connection – Variable-speed controls and a standard 120 V electrical connection simplify everyday operation.
• Service-Friendly Construction – Accessible drainage and durable, treated cooling media support routine cleaning and maintenance.

High-Volume Cooling Performance

The Big Ass Fans COOL-SPACE® 300 provides airflow ranging from approximately 700 to 2,800 CFM, helping distribute cooled air throughout the intended space or toward a targeted work area. With a maximum recommended coverage area of up to 1,200 square feet, the unit is suited to workshops, garages, studios, and other appropriately ventilated environments. Under favorable conditions, evaporative cooling can reduce air temperature by up to 33°F (approximately 18°C). Actual cooling performance depends on ambient temperature, relative humidity, ventilation, and the operating environment.

Direct Evaporative Cooling Technology

The Big Ass Fans COOL-SPACE® 300 uses direct evaporative cooling technology to cool incoming air as water evaporates from its 8-inch-thick, cross-corrugated cellulose cooling media. An integrated water distribution system supplies the media, while the fan draws air through the wetted surface and delivers the cooled airflow into the surrounding space. The cooling media is treated and coated with thermosetting resin to resist algae and mold growth, withstand frequent cleaning, and help prevent dirt and other particles from penetrating the media substrate. This design provides targeted cooling for well-ventilated commercial and industrial environments.

Airflow and Distribution

The Big Ass Fans COOL-SPACE® 300 delivers variable airflow from approximately 700 to 2,800 CFM through an 18-inch-diameter fan. Its variable-speed control allows users to adjust the airflow to suit changing cooling requirements, from localized spot cooling to broader air distribution within the unit's intended coverage area. The direct-drive fan design supports efficient operation without the need for a belt-driven transmission.

Portable and Flexible Installation

The self-contained portable design allows the Big Ass Fans COOL-SPACE® 300 to be positioned where supplemental cooling is needed without requiring a permanent HVAC installation. The unit measures approximately 26 inches wide, 24 inches deep, and 49 inches high, with an operating weight of approximately 100 pounds. Caster wheels support movement between work areas, while the onboard water reservoir enables operation without a continuous external water connection for a limited period. The cooler can also be supplied through a standard garden hose connection when a suitable water source is available.

Water Management

The Big Ass Fans COOL-SPACE® 300 incorporates a 16-gallon water reservoir to supply its direct evaporative cooling system. The reservoir provides up to approximately four hours of operation on a single fill under suitable operating conditions. A standard garden hose connection supports convenient water replenishment, while an integrated float valve helps regulate water supply when connected to a suitable water source. An automatic low-water shutoff helps protect the unit when the water supply becomes insufficient, and an accessible drain plug facilitates reservoir drainage during maintenance or when preparing the cooler for storage.

Controls, Comfort and Electrical Connection

The Big Ass Fans COOL-SPACE® 300 features variable-speed controls that allow users to adjust fan airflow to suit their comfort and cooling requirements. Its direct-drive fan motor supports quiet operation compared with many conventional belt-driven arrangements. The F-EV1-1801 model operates on a 120 V AC, single-phase, 60 Hz electrical supply, draws approximately 4.1 A, and uses a NEMA 5-15P plug. It is supplied with a 10-foot power cord and onboard cord storage for convenient handling when the unit is moved or put away. Confirm that the electrical supply and circuit meet the manufacturer's requirements before operation.

Commercial and Industrial Applications

The Big Ass Fans COOL-SPACE® 300 is designed for well-ventilated indoor and outdoor applications, including workshops, garages, studios, warehouses, and other work areas requiring supplemental cooling. Its portable construction, adjustable airflow, and self-contained water reservoir make it suitable for targeted cooling where installing or extending a permanent air-conditioning system may not be practical. Evaporative cooling is generally most effective in hot, dry conditions; its cooling capacity decreases as ambient relative humidity increases. Adequate ventilation is important because the system adds moisture to the air.

Mobility and Deployment

The Big Ass Fans COOL-SPACE® 300 features a compact, wheeled design with caster wheels for repositioning between work areas. Its approximately 49-inch height, 26-inch width, and 24-inch depth allow the unit to be deployed in a variety of workspace configurations. The 16-gallon internal reservoir provides temporary water-independent mobility, while the standard hose connection supports extended operation when a suitable water supply is available. The onboard cord storage helps keep the power cord organized during transport and storage.

Service and Maintenance

The Big Ass Fans COOL-SPACE® 300 incorporates treated cellulose cooling media designed to resist algae and mold growth and withstand frequent cleaning. Routine maintenance should include inspecting and cleaning the cooling media and water reservoir as directed in the manufacturer's operation and maintenance instructions, checking the water supply and float valve, keeping the drain accessible, and inspecting the power cord and plug for damage. Drain the reservoir and prepare the unit for storage in accordance with the manufacturer's instructions. Always disconnect electrical power before performing maintenance or cleaning components that require access to internal parts.

Warranty

The Big Ass Fans COOL-SPACE® 300 is listed with a manufacturer warranty of five years for the main fan unit and one year for other components in certain product documentation. Warranty terms and component coverage may vary by applicable warranty document, purchase date, and sales region. Consult the warranty supplied with the specific F-EV1-1801 unit and the manufacturer's current warranty terms to confirm coverage, exclusions, and any registration or installation requirements.
