Ventilation systems and devices - destratification fans of the HC-3S series are designed for residential premises. Destratification fans, also known as air mixers, are devices that blow warm air from the upper parts of a room into the occupied area. In this way, the heated air is effectively directed downward. Destratification fans are intended for use in industrial premises with a height of min. 4 m, for example warehouses, production halls or shipping centers. Due to their design specifics, these objects are by definition subject to special restrictions in heat distribution.
