10 or 20 liters, and the 30 doubles the torque
The 15 states 10 L, 15 N·cm and 8000 mPa·s at 100-1500 rpm; the 30 rises to 20 L, 30 N·cm and 16,000 mPa·s while turning slower (50-1200 rpm): it enters liquids twice as viscous in exchange for speed ceiling.
S or Pro: the base and the paddle
The catalog's note is verbatim: the S has an H-base and its paddle cannot pass through the head; the Pro has a non-slip base and the paddle can. The mixing figures are identical between the two.
