ZOO Fans and Airius* Performance Comparison

See how ZOO Fans™ Blows Away the Competition

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. Some fan manufacturers only provide performance numbers for the fan motor in free air, not in their fan housing. Watch out for these claims! They neatly side-step the most important information — the impact the fan housing has on 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 do they do it? Maybe it’s because they know that their housing significantly degrades the performance of the fan motor. Or maybe it’s because it sounds better to claim higher performance, even if its not what you end up getting.

At ZOO Fans, we think that you should know what you are buying. Our fans’ performance numbers are tested in an independent, third-party industry certified lab and rate the fans in their housing! Third-party data on things like CFM and throw – that’s the information you really need.

In particular, watch out for fan housings that have nozzles, or a narrowing tail pipe. While this type of design works great with water, 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, can overheat the bearings and shorten the life of the motor. No amount of fins or stators will fix this problem, otherwise there would be no reason for competitors to obscure their fans’ actual performance.

Destratification fans can improve comfort and lower operating costs in just about any type of heated or cooled space. At ZOO Fans, in addition to fans for open ceilings, we also offer fan systems with EnergyStar®-rated fan motors for suspended ceiling (or drop ceiling) spaces. ZOO fans include an air guide, or stator ring that significantly improves the performance of the fan.

So remember, when shopping for destratification fans, make sure you are not comparing an Apple to a Pear — instead, compare apples to apples. To get the facts about the real efficiency of different fan models, be sure to ask for third-party performance data from an industry certified lab for the fans in their housing. Anything else is just marketing “smoke and mirrors.”
