15-25: Leveling the Playing Field for Axial Impeller Comparisons and Regulatory Legionella

15-25: Leveling the Playing Field for Axial Impeller Comparisons and Regulatory LegionellaAxial Impellers are integrated as driven impellers in multiple non fan products, including cooling towers. However, there is no common rating standard for axial impellers. That means that a level playing field for axial impeller performance comparisons is absent. No commonly accepted standard for comparing axial impeller data on an apple to apple basis exists. There is no commonly accepted guide for compliance officers to follow to support the
