Neptune’s extensive line of portable mixers also include direct drive air-driven mixers. Neptune’s BF Series flange mounted air-driven mixers are available in both single and dual propellers. Single propeller models have one left-handed propeller pumping downward in normal operation. Dual propeller models have one each left-hand and right-hand propellers providing counter flow mixing.
Neptune’s BC Series clamp mounted air-driven mixers feature a knob and handle. The knob allows the clamp to be loosened without tools to adjust the shaft angle and the handle allows a firm grip on the mixer when adjusting the position. The BC Series also features three blade left-hand marine propellers that pump downward in normal operation.
