The Feature-Packed Swamp Cooler

Like all products that bear the Big Ass Fans name, our newest evaporative cooler is engineered to provide you with top-of-the-line performance and features. That means automatic low-water shutoff for increased longevity, resin-treated cooling media for the prevention of algae growth, and easily accessible reservoir cap for convenient maintenance. Each Cool-Space 350 unit is also equipped with GREENGUARD Gold-certified cooling media for cleaner, safer air.

The Ultimate Cooling Combo: Swamp Coolers and Big Fans

Unlock your evaporative cooler’s maximum cooling potential by pairing it with a large overhead fan. Big Ass fans take the cold air produced by your cooler and circulate it to every corner of your space. And because fans and coolers provide heat relief in two different ways, this pairing is more powerful than the sum of its parts!


“Here in Arizona, fans and swamp coolers are necessary for the summer. We wouldn’t get much production from our welders without them. The cooler air pushed through weld cells and larger projects outside are great. We have overhead ceiling fans and swamp coolers; the backing/follow up and service from Big Ass fans has been phenomenal.”
