Air RotationJohnson MarCraft Air Rotation Unit

When Johnson MarCraft expanded the air rotation concept from heating to cooling, we found the same air mixing principles held true – the delivery of cooled air, high into the conditioned space, provides for even temperature distribution, low stratification numbers and lowered energy consumption.

The general concept of air rotation is to return all the air in the space to an air rotation unit a sufficient number of times per hour to ensure an even distribution of the cooled air, which results in an even temperature distribution.
