Make Sure you Aren’t Comparing an Apple to a Pear!
Are you searching for an effective way to improve the heating, cooling and circulation of air in your building? But you’re finding it’s not easy to compare the performance claims of one product to the next? A variety of fans are available and the manufacturers make various claims about how they perform, so it can be a challenge to compare them. Fortunately, much of that work has been done for you through independent, third-party testing.
Not all Destratification Fans are Created Equal
Destratification fans are becoming more and more popular as a means to save energy and noticeably improve comfort by recycling conditioned air and improving circulation. But not all destratification fans are created equal. Watch out for asterisks! *
Some fan manufacturers only provide performance numbers for the fan motor in free air, not in their fan housing. This is done to side-step the most important information — the impact the fan housing has on overall performance.
Free air fan performance is interesting, but not particularly useful when trying to specify the correct number of fans for a job. So why not provide fan performance for a fan in its housing? Because some other fan manufacturers know that their housing significantly degrades the performance of the fan motor. It sounds better to claim higher performance, even if it’s not what you end up getting.
With ZOO Fans our performance is better so you need fewer fans to do a better job. Lower equipment cost, lower installation cost, and lower operating cost—performance counts.
Watch Out for Nozzles
Watch out for fan housings that have nozzles, or a narrowing tail pipe. While a nozzle can be effective with some types of fan design, it is strongly advised against by fan engineers for the small, axial fan motors used in these types of fans. The nozzle causes undesirable turbulence and back pressure that reduces airflow significantly, can overheat the bearings and shorten the life of the motor. No number of fins or stator rings will fix this problem, as some of our competitors may claim.
Our H-Series ZOO Fans have no nozzle. Our fan engineers said to leave the nozzles to big, multi-horsepower fans, or to use rugged mixed-flow impellers, like the ones used in the ZOO Fans IC-Series. ZOO Fans designs don’t choke the motor, instead our motors produce significantly more air, more economically.
The stator-ring used in the ZOO Fans H-Series is a far superior design than the one used by the competition. How do we know? Again, independent third-party testing.
At ZOO Fans, we think that you should know what you are specifying and buying. Reliable data on things like CFM and throw for the fan motor in its housing – that’s the information you need.
So, remember when shopping for destratification fans to be sure you are not comparing an Apple to a Pear — instead, compare Apples to Apples. Get the facts about the real efficiency and performance of different fan models—just ask for fan performance data for the fans in their housing!
Anything else is just marketing “smoke and mirrors.”
