Optimal two bladed design creates down flow in the center and up flow at the wall, creating a complete turnover of tank's contents
Provides similar blend time for less power than traditional open impellers (A320, A200) and less torque (lower cost) than traditional close clearance impellers (A400, R400)
Operates at high impeller diameter/tank diameter ratios, which improves heat transfer at the wall
Bolted construction available for tanks with small diameter manways
