Rated 5 out of 5 by from BAF 400 I lease my building so I wanted something I could take with me when I moved on, I had looked at these a few times but never followed through. I wish I would have bought this years ago it is perfect for our warehouse! I was worried about it actually working, but once you get your fan speed and water flow dialed in it does a great job I would recommend this fan to anyone with warehouse or shop space!

Rated 3 out of 5 by from Loud The fan works well and cools down our space by 10 degrees. The only issue is that it's just really loud at the highest fan speed. Can't hold a zoom meeting at that setting. At the lowest setting, it's much quieter but there's a hum which is annoying.

Rated 5 out of 5 by from Wonderful product We have had the fans for a full year and in Alabama we go from freezing temps to 100 plus temps. The fans are able to cool us in all the metal buildings with no AC assistance and help distribute the heat in the winter months. They are easy to use and the digital pad make it easy to monitor and set patterns. We have loved the product and will continue to be lifelong customers. Thanks

Rated 5 out of 5 by from Amazingly Cool! We purchased two of these for our Coachella location/warehouse. In the dead of summer when it's 120 degrees these things make it feel like its a balmy 75. This allows us to continue to be productive and keeps our associates safe from any heat injuries. The Big Ass Fan team is awesome, they got back to us in a timely manner and our product was delivered right when we needed it.

Rated 5 out of 5 by from Game changer for our barn event venue. We purchased the cool space 500 for our 5,000 sq. ft. Barn wedding venue. Summertime in Maine can be searingly hot. Regular fans were not doing the trick for us at The Barn at Silver Oaks, an upscale event venue where weddings are conducted every Saturday from May through October. Our guests are always in suits, ties, dresses and vests. Keeping these folks cool, especially while dancing, was not easy. After adding the evaporative cooler was the best thing we could have done, and afforded. My HVAC company gave me a quote for $120,000 dollars to cool our space. This unit, while hooked up to a hose runs for 16 hours a day and keeps everything tolerable and we roll it on to the dance floor full blast and everyone loves it. The hardest part about this fan is forcing a smile when the 178th person in a row walks by and says, “that’s a big ass fan!” Gene Carbona, owner The Barn at Silver Oaks Maine

Rated 5 out of 5 by from Well Built! We use it in a fabrication shop in CT. It cools our 5600 square foot shop and makes it comfortable to work during the hot summer months. We have found that it works better with our overhead door open. Fan is very well made. It does use more electricity than we originally thought but still well worth the money. We would purchase this product again if we had to.

Rated 5 out of 5 by from awesome product that delivered as advertised We bought the cool space 400 after a long and hot summer. Our employees loved the cooler temperatures and this big ass fan provided a more pleasant working environment. The order delivered with a reasonable turnaround time and was properly packaged for easy installation and set up. The team at big ass fans is great to work with.

Rated 5 out of 5 by from Keeps us cool! We purchased the 400 model back in the Spring season, and being located in Texas - we were worried it would not keep up during our Texas summers! We use this in an old airplane hanger building, and combined with the fan unit we have hanging from BAF, it easily keeps the temps 10-15 degrees cooler than outside! Worth every penny.

Rated 2 out of 5 by from Falling apart The bolts holding the frame that holds the motor have backed out. We have had to pull the thing apart to re-thread the bolts. We also used a nut outside to solve the bolt from backing out again.

Rated 5 out of 5 by from Cool - Space 400 We bought two of the fans for our shop. They move a lot of cool air and are extremely quiet. They have a large reservoir for water which in our environment last about 6 hours. We are fortunate enough to keep a water hose hooked up directly to the units. I would highly recommend them. Great units and great customer service.

Rated 5 out of 5 by from Great cooler for a large space We received this unit for out large warehouse in CA where it regularly hits almost 100 in the shop. Cools us down as well as gets the air moving. Great unit and would definitely recommend for anyone with a large space and needs to take the edge off. We also love that it has a remote to control it from a distance.

Rated 5 out of 5 by from BAF Cool Space Fan Our company purchased 2 of these BAF cool space evap fans, best decision we have made. We have a warehouse with no central air or way to cool the building.

Rated 5 out of 5 by from They get the job done. We bought several of these for our warehouses in Phoenix. They do a phenomenal job keep the warehouse and staff cool. We also use these in a structural steel plant and like our warehouses it keeps our staff cool while they're welding and fabricating steel in the 100 degree Phoenix temperatures.

Rated 5 out of 5 by from Great Addition to our Facilities The addition of our Cool - Space 400's to our manufacturing facilities has been a great help to reducing the heat in both plants. We can see the results of the lower temperatures in our production numbers during the high heat days. Our production employees really appreciate the investment.

Rated 5 out of 5 by from Great Workmanship The quality of the product is excellent. Having received the unit late in the year, I haven't been able to fully appreciate the capability of the unit. I can vastly tell a difference in the output air temperature when the pump is not running. Looking forward to warm weather!

Rated 5 out of 5 by from Meets our needs - great service We spoke with the team at BAF to select the right number of fans and use for our space. This was the first year in 10 years we've not had a customer complain about heat all summer long. The machine itself is very simple to use and does exactly what we expect of it.

Rated 5 out of 5 by from Drops the temp 20-30 degree!! We bought this for our shop. We have a metal building 60*100 with three bays. In the summer it would get up to 100 degrees in the shop. Using two large ceiling fans and the cool space 400 we dropped the shop temp 20-30 degrees!!! Its like having A/C blowing on you.

Rated 5 out of 5 by from Amazing product to cool the space I bought this for a 10,000 square foot rooftop which did not have any HVAC set up. We were operating events such as weddings and corporate parties and it cooled down our space TREMENDOUSLY. Although the unit is large in size, it is wonderful to cool down a space.
