Big Ass Fan Cool-Space 400

A substantial workhorse designed for use in large spaces like gyms, production facilities, and covered outdoor dining areas, the Cool-Space 400 evaporative cooler from Big Ass Fans delivers instant airflow that can lower the air temperature of a space by up to 33 °F (18 °C), offering cooling relief in a powerful but quiet unit.

The 400 model includes a 36” diameter fan (twice the size of the 300 model), a 46-gallon water reservoir, and a direct-drive motor with variable-speed controls, enabling precise cooling for a fraction of the cost of traditional air conditioning. 

Each unit utilizes the industry’s most effective and longest-lasting cooling media. Chemically treated and coated in a thermosetting resin, this media not only evaporates more heat than the competition, but also resists the growth of algae and mold and prevents dirt and other particles from penetrating into the substrate.

To keep the water supply of the Cool-Space 400 filled, all you need is a standard garden hose. The Cool-Space unit is conveniently portable, and its large internal reservoir can help it run for hours without being connected directly to a water source.
