Juice losses are minimized as bottom fans do not need work high speeds. To optimize the bottom fan efficiency GT3 is equipped with MAXflow system. 2 trapdoors located each side of main conveyor, underneath bottom fans, adjusts air intake to fans for an optimum MOG extraction. Trapdoor position and air intake can be adjusted in seconds depending of harvest conditions.
