a. Indicated capacities are typical for normal materials, 0.7 gr./cm3 bulk density

b. Optional, requires hardware modification (revolutions sensor)

c. The low-capacity screw is sensitive to hard flowing material, or electrostatic charge, especially at high revolutions. Therefore, it is not recommended for use when a current of over 60% is required. In this case, it is recommended that you use the medium-capacity screw and not the low-capacity one

d. Extra-capacity screw is recommended for "hard" dispersing (flowing) materials.
