Heat can cripple your facility’s production and put your people at risk. For a rapid, effective response, rely on Cold Front evaporative coolers. Combining powerful, quiet direct-drive fan technology with a water supply and saturated cooling medium, Cold Front 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 outdoor spaces
  • Industry-leading 5-year warranties


Cold Front coolers are designed with the industry’s most effective and longest-lasting cooling media. Thicker than competing products’, Cold Front’s media evaporates more heat from your space for a greater cooling effect. The 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 Cold Front cooler’s water supply. For facility managers who need maximum portability for immediate spot-cooling, Cold Front coolers feature large internal reservoirs that can run for hours without being connected to a water source.


With Cold Front’s variable-speed controls, maintaining the perfect temperature for your space is as simple as turning a dial. Designed for convenience, all Cold Front models feature locking swivel casters, automatic low-water shutoff, and an easily accessible drain plug, while larger models are equipped with a GFI plug and cord wrap for safe, portable operation.


Cold Front coolers feature virtually silent 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, Cold Front 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 Best Invention of Earth! Even Thomas Edison would be "shocked" at the electrifying results of this amazing weather creator. When paired with the incredible fans we purchased from you previously, this powerful blizzard like air mover actually reduced the air temperature in our facility. It creates tornado like conditions with hot air being pushed down, cold air mixing, and BAM...tornado! Highly recommended for anyone that is looking for a chill in the air.

Rated 4 out of 5 by from Definitely Cool We bought two of these several weeks ago. We heard that they blew cold air. We were skeptical, but once installed... sure enough... they blow distinctly cooler (if operating with water) Variable speed control is a nice feature. It's easy to set up and operate. The employees really like them. I deducted one star due to the size. They require a fairly large area and they drink a good bit of water. Having stated that, once hooked up and operating - they live up to the billing. Of our 2, one is hooked up directly to a faucet. The other is hooked up to a pump & reservoir.

Rated 5 out of 5 by from This WORKs Great! Looks like your engineers were spot on. Two Units can do our job beautifully. We are finally getting some warm weather and had a chance to test them out. They work even better than expected. I was leery of using one in an office environment with people on the phone and working with customers. No problem though. Is it loud? Sort of, I can hear it but, I can use the phone, speak in a normal tone and hear just fine. The big thing is it’s cool. You said it can drop the incoming air temperature 20 degrees, yes it can, we measured the temperature and it went to 22 degrees about 6 feet in front of the outflow. The 300 is more than adequate for our 1100 square foot office and the 500 should handle our 1800 square foot bindery just fine. We did measure a 12% rise in humidity from 24% to 36%. That’s great! We are a print shop and static is an ongoing problem. 40% to 50% is ideal for us but, 36% keeps the static problem in check quite well. Our Big Ass Fans do the job for us and we expect to finally have a comfortable summer.

Rated 5 out of 5 by from Awesome Product Have always been a "fan" of the larger Big A** Fans, didn't know they were selling the swamp coolers until recently. We had a hot spell recently and we were able to buy and receive the 500 Cold Front for our shop in a matter of days. Awesome sales group who recommended the perfect size for what our team needed.

Rated 2 out of 5 by from Not what we expect from BigAss Casters do not go all the way in, so makes it wobbly. Instructions are very bad. To clean you should take out filters, but they are made of paper and they crumble. Impossible to get them out.

Rated 2 out of 5 by from Very Disappointed Extremely loud. I specifically called about the noise level and was advised to purchase the larger motor which I did. On low the noise isn't bad but it barely cools and as you increase the speed the noise increases as well. Not at all what I expected.

Rated 5 out of 5 by from Finishing Touch to Employee Comfort The two Cold Front 400 units we tested were the perfect addition to our assembly operations area in combination with Powerfoil X ceiling fans and a building exhaust fan to keep the area fed with fresh air cooled by the CF 400's. The workforce liked the effect enough that we have ordered six additional Cold Front units for the other work areas.

Rated 1 out of 5 by from Doesn't Work We bought the Evaporative Cooler 200, unboxed it and it didn't work. We requested a new one which was to ship the following week. Then, when we called to check on the ETA, they said it wouldn't ship for several weeks. So, BAF agreed to refund us the money. They would tell us what to do with the new defective cooler that they shipped. Then, the second cooler arrived - this is the cooler that wasn't supposed to ship. Now we have 2 coolers. I asked them to tell us how they want to handle the original cooler return since the packaging was thrown away when we unpacked the original cooler since we expected it to work right off the assembly line. We received a dual RMA, but no instructions on how to ship back the original cooler.Customer service is great when you call them, but there isn't any quality in the follow up on what was agreed upon, time after time.
