Recirculation System
Roof ventilator recirculation are multi-purpose power roof ventilators. They are suggested for use in commercial and industrial applications where there is sufficient ceiling height to create a temperature differential between the floor and ceiling. These applications include factories, warehouses and large commercial buildings. These roof ventilator recalculates function as normal power roof ventilators in warmer weather and as an energy saving recirculation system in cold weather. Each unit is equipped with a reversible fan that redistributes warm ceiling air throughout the plant and reduces the building's heating requirement. With the flip of a switch, it can function as a conventional roof ventilator.
