The fan is completely hot dip galvanized. It can easily be installed to the roof construction with chains. Polluted air is removed through the air corridor created inside the barn or in the milking parlor waiting area.
High capacity can be reached by low power consumption and low rpm. This low rpm (340 rpm) also decreases fan blade noise. It is located with intervals of 18-22 meters when minimum expected air speed is 3 meters/second.
