We purchased new in August 2024. Used 5 times in July 2025. Works perfectly. Problem for our business is we make wood furniture and it increases the humidity in our shop. This isn't a problem for many industrial operations or personal ranch use. It cools great and we wish we could use it in this hot CO summer. Current list price $4200 with sale price $3200 at Big Ass Fans. This is a great deal!
The Big Ass Fans Cool-Space 400 evaporative cooler is perfect for production facilities, warehouses, outdoor events and gyms up to 3,600 square feet.
Easily reduce the temperature in your space by up to 33 degrees F to keep your guests or employees comfortable even in harsh summer weather:
Powerful Cooling: Powerful 36-inch fan diameter moves air faster than comparable units. This fan moves air up to 9,700 CFM to maximize spot cooling right where you need it.
Thick Cooling Media: The resin-treated cooling media that cools air is 8 inches thick, making it more effective at evaporating heat and more durable to last longer.
Massive Water Tank & Continuous Fill: Large 46-gallon water reservoir with continuous fill means you’ll enjoy refreshing cool air for hours at a time. Add a hose for continuous use without having to refill the tank.
Adjustable Cooling: Variable speed, totally enclosed 0.75 horsepower motor is tested before sale. Easily adjust the cooling speed with the knob on the control panel.
Affordable to Run: Unlike many cooling options, evaporative coolers are inexpensive to run. They don’t use compressors; simply set it up and add a water source for immediate relief.
Continuous Use
The Big Ass Fans Cool-Space 400 has a large 46-gallon reservoir you can fill up as needed, but you can also attach a standard garden hose for continuous use. It can run for hours without the hassle of re-filling the unit once the hose is attached.
