High Efficiency Non Ragging Formed Axial Impeller
Abstract: An axial impeller has blades formed from sheet metal blanks that are configured from taking a desired impeller blade and mathematically "unwinding" the blade to its flat counterpart. Preferably the impeller blade is formed from a single rolling operation. The result of a thin elongate blade preferably having a trailing edge that defines a helix with rearwardly skewed forwardly raked blades provides an efficient impeller having good anti ragging properties.
