Product Details

Heat can cripple production and put your people at risk. Cold Front evaporative coolers, also known as swamp coolers, provide a rapid, effective response. 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. Pair your Cold Front coolers with Big Ass overhead fans to deliver the benefits of powerful spot-cooling and elevated air speed to every corner of your facility. When used in tandem with overhead fans, Cold Front coolers provide maximum cooling and coverage areas, silently delivering comfort and energy savings to your facility without costly A/C use. 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. Cold Front provides a variety of sizes, with the perfect combination of power and efficiency to keep your space comfortable, whether sitting on a patio or working in a massive warehouse.

    Answer This Question

    A:  Hi Lynda! There is no mist that comes from the units. It doesn't add noticeable humidity as long as the space is big enough, or if you have any form of ventilation. The natural humidity within your building at 6 am will be higher than it will be when the units are in use. Please give us a call at 877-BIGFANS if you have any additional questions.

      More like BAD ASS FANS!
      [This review was collected as part of a promotion.] 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.
        Super Cool
        [This review was collected as part of a promotion.] We purchased these fans back in September of 2022. The performance is just outstanding. The best choice we have made for this area of ours.

          Big A** Fan Review for Brewery
          [This review was collected as part of a promotion.] 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!

            Huge difference
            [This review was collected as part of a promotion.] We purchased 3 of these coolers for our weld shop in Phoenix, AZ. Two of them are in an outdoor area where we building a big project. These coolers have allowed our welders to work during the day in temps over 100 degrees. What a difference the cooler air is in this area. The other cooler is in our maintenance shop and has cooled off this area significantly.

              Simple to operate, colder air than an ac unit
              [This review was collected as part of a promotion.] Never imagined an evaporative cooler to cool room efficiently. Minimal noise, low maintenance.

                Fan Tastic
                [This review was collected as part of a promotion.] Very Impressed with this product. Not a joke when you say Big Ass Fan, Working in Arizona 110 degree temps can really slow production down causing us to end the day around 2:00 pm, with this fan we can work until 5:00 and add 15 hours of production per week that results in 8000 per month, Its not about can I afford this fan its about you cant afford not to have this fan. Simple math fan has already paid for itself in first season and will last for many more.

                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.

                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.
