Big Ass Fans Cool-Space 300 Evaporative Cooler

Beat the Heat with Compact Industrial Cooling

Heat can cripple your facility’s production and put your people at risk. For a fast, effective solution, count on the Cool-Space 300 from Big Ass Fans. This compact yet powerful evaporative cooler uses quiet direct-drive fan technology, a saturated cooling medium, and internal water reservoir to reduce air temperature by up to 33 °F (18 °C)—keeping your workspace safe and productive without the high cost of traditional A/C.

Thicker, More Effective Cooling Media

The Cool-Space 300 features the industry’s most advanced and long-lasting cooling media. Thicker than competitors', the 8-inch evaporative media delivers superior heat absorption and cooling performance. It’s coated with a thermosetting resin and chemically treated to resist mold, algae, and dirt—ensuring optimal operation even after frequent cleanings.

Large Internal Reservoir for Portability

This unit connects easily to a standard garden hose, but also features a 16-gallon internal reservoir for up to 4 hours of stand-alone cooling—perfect for spot-cooling workshops, garages, and small warehouses.

Simple, Safe Operation

The Cool-Space 300 is designed for ease of use with variable-speed control, locking swivel casters for mobility, and an intuitive drain plug. Safety features include automatic low-water shutoff and a GFCI plug with cord wrap for reliable operation indoors or out.

Quiet, Energy-Efficient Performance

Powered by a whisper-quiet 0.5 HP direct-drive motor, this compact cooler moves 2,800 CFM of air to provide targeted cooling where you need it. With significantly lower operating costs than A/C, it’s the ideal solution for small to mid-size commercial spaces.
