Heat can cripple your facility’s production and put your people at risk. For a rapid, effective response, rely on Cool-Space evaporative coolers. Combining powerful, quiet direct-drive fan technology with a water supply and saturated cooling medium, Cool-Space delivers instant airflow that lowers the air temperature of your space by up to 33 °F (18 °C), creating comfortable conditions that keep your people safe and productive.

  • Quiet, efficient variable-speed motors
  • Thick, resin-treated cooling media
  • Uses standard 110 V power supply
  • Internal water reservoir supplied by standard garden hose
  • Suitable for indoor and covered outdoor spaces
  • Industry-leading 5-year warranties


Cool-Space coolers are designed with the industry’s most effective and longest-lasting cooling media. Thicker than competing products’, Cool-Space media evaporates more heat from your space for a greater cooling effect. This Green Guard certified media has been chemically treated and coated in a thermosetting resin to resist the growth of algae and mold, hold up to frequent cleanings, and prevent dirt and other particles from penetrating into the substrate.


A standard garden hose is all that’s required for each Cool-Space cooler’s water supply. For facility managers who need maximum portability for immediate spot-cooling, Cool-Space coolers feature large internal reservoirs that can run for hours without being connected to a water source.


Cool-Space features a control panel, premium remote, and occupancy sensor for hands-free operation. The model’s Auto-Dry feature maintains the unit after each use, extending the life of the cooling media and keeping your cooler in peak condition.


Cool-Space coolers feature direct-drive motors and variable-speed controls that allow you to deliver precise cooling throughout your facility for a fraction of the cost of traditional A/C. With a range of sizes and horsepowers, Cool-Space motors offer the perfect combination of power and efficiency to keep your space comfortable, whether you work in a two-car garage or a massive warehouse.

Rated 5 out of 5 by from Amazing Product with better than expected results! We recently expanded from 30k sq/ft to 90k sq/ft warehouse. By June the inside temps were reaching well into the upper 90's inside making it unbearable for our staff to work comfortably. I reached out to Big Ass Fans for a quote and they sent a sales rep. over the next day. They reviewed the area we were wanting to cool and came back with several options. We chose (2) of the Cool-Space 400's to circulate the air. Within hours of installation they had cooled the inside temp dramatically and everyone was happy!!! We could not be more pleased with our purchase! Not to mention their customer service is also A+. I would recommend this product to anyone wanted an instant solution and a cooler work environment!

Rated 5 out of 5 by from Dependable, great service and backing. Here in Arizona fans and swamp coolers are a necessity in the summer. We wouldn't get much production from our welders without them. The amount of cooler air pushed through weld cells and larger projects outside is great. We have overhead ceiling fans and swamp coolers; the backing/follow up and service from Big Ass fans has been phenomenal.

Rated 5 out of 5 by from Nice and Cool! Great addition to the plant! I purchased two of these units for our production facility. The plant is not air conditioned, so hot and humid days can be a bear in the summer. The units were placed to blow cool air on employees and WOW were they super appreciative of the cooling. The first day the team even said they had to turn it down because it was so cold. They mostly ran the fan on low with the water pump on. Direct water hookup ability is nice to ensure the fan always has water. Overall great purchase and improvement for employee well being.

Rated 5 out of 5 by from Big A** Fan Review for Brewery Hold Fast Brewing in Springfield, MO does not have internal air conditioning. With the summer, specially June of 2022, getting SO hot last year it impacted business; we then made the decision to invest in a Big Ass Fan. It was the best thing we could have done, we have a large taproom and it adequately cooled it down a noticeable amount. It’s now a summertime staple that continues to allow us to serve the community year-round. We love it!

Rated 5 out of 5 by from I need cool air! We are very happy with the Cool-Space 400's we ordered for our plant. They lower the temperatures and it spreads out to the extent of our Big Ass Fans capabilities (about 110ft). Staying close to a water source or installing a water line ensures the tanks stay full and works as it should. Great product!

Rated 5 out of 5 by from Takes the edge off We have been using the product for a year now and the guys love it. We have two units that provide excellent coverage for our shop. On those hot days they put out a nice cool flow of air. Depending on humidity level they drop the air temperature 10-15 degrees. Absolutely takes the edge off.

Rated 5 out of 5 by from More like BAD ASS FANS! Nothing but good things to say about the 3 Cool Space 500's I got....meeting the guys from BAF at the ARA show last year was the beginning of a smooth purchasing experience, followed by a reasonable delivery time and finally a killer product. Customer service/warranty was top notch as well.

Rated 5 out of 5 by from Great for manufacturing production floor. We run a lot of ovens in our production and the facility can get very hot in the summer and still pretty warm in the winter. Our production floor employees were relieved when we purchased a couple of these fans. They really do push cooler air. Our shop employees really do like these and have been a big help on the floor. We had previously purchased another brand and the BAF were a lot more solid and better build to last. Highly recommend and will keep purchasing these from BAF.

Rated 5 out of 5 by from More than expected, great company After searching around online I finally decided to buy the unit and boy I’ll tell you, I made the right decision. If you are considering a portable cooler this is it. One thing that I’ve learned is to be frugal with how much water you put on the pads. Less is more . It will cool better with less water running.

Rated 5 out of 5 by from Big ass fan cooled us down!! We bought the fan to help on job sites to cool us down. It did an amazing job. Customer service was great, they put up with me asking a ton of questions. Delivered safely, well secured for delivery. We have used just the fan, and with water for cooling. Thank you we will buy again from you.

Rated 4 out of 5 by from Cool Space 400 We bought this product in the summer to try and cool our shop down. Product is very well made, but we ended up returning the unit. It just didn't work for our application. The return process was straightforward and I would definitely recommend considering this product if it fits your needs.

Rated 4 out of 5 by from Great for outdoor or less humid spaces I tried this out in my woodshop that didnt have AC. It definitely did what was advertised, however it did cause a rise in humidity which caused an issue with the wood I was working with at the time. It'll be great for me in less humid times of the year though. Well made, easy to use.

Rated 5 out of 5 by from Helps fight Houston humid summers We bought this to help cool down an unconditioned Houston warehouse space in the summer. Combined with the Basic 6 fan it does a great job cooling down our staging area by about 10 degrees. It puts out a nice strong and cool breeze.

Rated 5 out of 5 by from Cool-Space 400 great product with high quality. Our metal door shop fabricators love the Cool-Space 400. It functions flawlessly providing a comfortable working environment for our staff even at 100 degrees. Wish we would have purchased it years ago. Thanks' Big Ass Fans!

Rated 5 out of 5 by from Awesome Fan We're using it at my tire center, in south Texas. It gets over 100 degrees here in the summer so it makes a huge difference. Flows a ton of air and is quiet. Made the working conditions here 10x better. Highly recommend.

Rated 5 out of 5 by from COOL SPACE We bought two of the Cool-Space 300's for our manufacturing floor. In the summer our production floor exceeds 100° on a daily basis. These fans cool down areas for our employees by 15-20°. Our employees love them!

Rated 5 out of 5 by from Kitchen Cool We purchased three of these units to keep in our kitchens and to use on our porch during the summer months to keep our staff and members cool. These fans did a great job and was a huge relief from the summer heat.

Rated 5 out of 5 by from Great product I purchased two of these at the 2021 SEMA show for my team at Winnebago Specialty Vehicles. The two fans along with our AMU cool my shop down noticeably when all doors are left shut.

Rated 5 out of 5 by from Spectacular! We have 2 of these and need 2 more. They move a ton of air, are super quiet while moving a ton of air. So, the cooling extends deep into the shop. We have a 20,000 SQ FT warehouse and these have been working great! Also, you can tell the quality and caring these folks have when you see how they ship these things. Handmade wooden shipping base with heavy duty cardboard box around the whole thing. You can tell they care.

Rated 5 out of 5 by from Great use in our auction warehouse Two of the units were purchased for our auction warehouse. There’s no AC and both units have helped to make summer work more enjoyable. Good quality units.
