How to Determine Left Hand vs. Right Hand Propellers

INDCO How to Determine Left Hand vs. Right Hand Propellers

The hand of your impeller and the rotation of your shaft will determine the flow of your material.  A propeller should be mounted to the shaft with the pitch-face in the direction of the flow desired.

When viewing into the container from above with a clockwise rotating shaft, a left hand propeller will direct material to flow down and a right hand propeller will direct material to flow up.  A counter clockwise rotating shaft will produce opposite flow results. With a counter clockwise rotating shaft, a right hand propeller will direct the material to flow down and a left hand propeller will direct the material to flow up.

See our video demonstration at for more details on determining the hand of your propeller.
